The mystic (yogī) tries to concentrate upon the Supersoul by controlling the senses from all other engagements, and thus he ultimately attains samādhi. A devotee more easily attains samādhi, or trance, by constantly remembering the Lord's personal feature along with His holy name, fame, pastimes, etc. Therefore, the concentration of the mystic yogī and that of the devotee are not on the same level. The concentration of the mystic is mechanical, whereas that of the pure devotee is natural in pure love and spontaneous affection.
(Srimad Bhagavatam----1:9:39----purport).

As it is stated in the previous verse, a person who has once offenselessly chanted the holy name of God becomes immediately eligible to perform Vedic sacrifices. One should not be astonished by this statement of Śrīmad-Bhāgavatam. One should not disbelieve or think, "How by chanting the holy name of the Lord can one become a holy man to be compared to the most elevated brāhmaṇa?" To eradicate such doubts in the minds of unbelievers, this verse affirms that the stage of chanting of the holy name of the Lord is not sudden, but that the chanters have already performed all kinds of Vedic rituals and sacrifices. It is not very astounding, for no one in this life can chant the holy name of the Lord unless he has passed all lower stages, such as performing the Vedic ritualistic sacrifices, studying the Vedas and practicing good behavior like that of the Āryans.
(Srimad Bhagavatam----3:33:7----purport).

One should accept the holy name of Kṛṣṇa to be identical with the Supreme Personality of Godhead, Transcendence Himself.
(Sri Caitanya Caritamrta----2:15:106----purport).

In the scriptures it is said that one can be liberated from the effects of all sinful actions simply by chanting the holy name of the Lord. One who takes advantage of this transcendental method and continues to commit sins on the expectation of neutralizing the effects of sins by chanting the holy name of the Lord is the greatest offender at the feet of the holy name. Such an offender cannot purify himself by any recommended method of purification. In other words, one may be a sinful man before chanting the holy name of the Lord, but after taking shelter in the holy name of the Lord and becoming immune, one should strictly restrain oneself from committing sinful acts with a hope that his method of chanting the holy name will give him protection.
(Srimad Bhagavatam----2:1:11----purport).

All potencies are invested in the holy vibration of the holy name of the Lord. There is no doubt that the holy name of the Lord, or oṁkāra, is the Supreme Personality of Godhead Himself. In other words, anyone who chants oṁkāra and the holy name of the Lord, Hare Kṛṣṇa, immediately meets the Supreme Lord directly in His sound form. In the Nārada Pañcarātra it is clearly said that the Supreme Personality of Godhead Nārāyaṇa personally appears before the chanter who engages in chanting the aṣṭākṣara, or eight-syllable mantra, oṁ namo nārāyaṇāya. A similar statement in the Māṇḍūkya Upaniṣad declares that whatever one sees in the spiritual world is all an expansion of the spiritual potency of oṁkāra.
(Sri Caitanya Caritamrta----1:7:128----purport).

Although sometimes we cannot see the gross body changing, chanting the holy name of the Supreme Lord immediately changes the subtle body, and because the subtle body changes, the living entity is immediately freed from material bondage. After all, changes of the gross body are conducted by the subtle body.
(Srimad Bhagavatam----5:1:35----purport).

One should understand that the name “Kṛṣṇa” and Kṛṣṇa Himself are identical. Any devotee who believes that the holy name of the Lord is identical with the Lord is a pure devotee, even though he may be in the neophyte stage.
(Sri Caitanya Caritamrta----2:15:106----purport).

One should not think that because Śrī Caitanya Mahāprabhu was personally present five hundred years ago, only His associates were liberated. Rather, Śrīla Narottama dāsa Ṭhākura says that anyone is a nitya-siddha if he acts on behalf of Śrī Caitanya Mahāprabhu by spreading the glories of the holy name of the Lord. We should respect those devotees preaching the glories of the Lord as nitya-siddha and should not consider them conditioned.
(Sri Caitanya Caritamrta----2:11:89----purport).

For persons who are not inclined to clean the dust from their hearts and who want to keep things as they are, it is not possible to derive the transcendental result of chanting the Hare Kṛṣṇa mantra. One should, therefore, be encouraged to develop his service attitude toward the Lord, because this will help him to chant without any offense. And so, under the guidance of a spiritual master, the disciple is trained to render service and at the same time chant the Hare Kṛṣṇa mantra. As soon as one develops his spontaneous service attitude, he can immediately understand the transcendental nature of the holy names of the mahā-mantra.
(Nectar of Devotion).

In the Narasiṁha Purāṇa it is said that as the hellish inhabitants began to chant the holy name of the Lord they began to be elevated from hell towards heaven.
(Srimad Bhagavatam----2:9:36-----purport).

At the time of death one is certainly bewildered because his bodily functions are in disorder. At that time, even one who throughout his life has practiced chanting the holy name of the Lord may not be able to chant the Hare Kṛṣṇa mantra very distinctly. Nevertheless, such a person receives all the benefits of chanting the holy name. While the body is fit therefore, why should we not chant the holy name of the Lord loudly and distinctly? If one does so, it is quite possible that even at the time of death he will be properly able to chant the holy name of the Lord with love and faith. In conclusion, one who chants the holy name of the Lord constantly is guaranteed to return home, back to Godhead, without a doubt.
(Srimad Bhagavatam----6:2:49-----purport).

A devotee should accept only those things that are favorable for keeping his body and soul together and should reject those things that increase the demands of the body. Only the bare necessities for bodily maintenance should be accepted. By making one's bodily necessities secondary, one can primarily devote his time to the cultivation of Kṛṣṇa consciousness through the chanting of the holy names of God. Pure devotional service means engaging all one's senses in the service of the Lord.
(Teachings of Lord Caitanya).

By offenseless chanting and hearing of the holy name of the Lord, one becomes acquainted with the transcendental form of the Lord, and then with the attributes of the Lord, and then with the transcendental nature of His pastimes, etc. Here it is mentioned that one should constantly chant the holy name of the Lord after hearing it from authorities. This means that hearing from the authorities is the first essential.
(Srimad Bhagavatam----2:1:11-----purport).

Being materially advanced means taking birth in an aristocratic family and possessing great wealth, an education and attractive personal beauty. All materialistic men are mad after possessing all these material opulences, and this is known as the advancement of material civilization. But the result is that by possessing all these material assets one becomes artificially puffed up, intoxicated by such temporary possessions. Consequently, such materially puffed up persons are incapable of uttering the holy name of the Lord by addressing Him feelingly, "O Govinda, O Kṛṣṇa."
(Srimad Bhagavatam----1:8:26-----purport).

That is the special significance of Caitanya Mahāprabhu's movement. He accepted Haridāsa Ṭhākura from born in Muhammadan community and He made him the ācārya, namācārya. The, practically Caitanya Mahāprabhu appeared to glorify the significance of the holy name. He is actually the ācārya, namācārya, but He transferred His namācārya-ship to Haridāsa Ṭhākura.
(Lecture on the Nectar of Devotion).

Śrī Caitanya Mahāprabhu was quite competent enough to spread His name and mission all over the world, but still He depended upon His devotee to do this work.
(Srimad Bhagavatam----6:19:5-----purport).

Śrī Caitanya Mahāprabhu, in His Śikṣāṣṭaka, declares clearly that the holy name of the Lord has all the potencies of the Lord and that He has endowed His innumerable names with the same potency. There is no rigid fixture of time, and anyone can chant the holy name with attention and reverence at his convenience.
(Srimad Bhagavatam----1:2:17-----purport).

By minimizing bodily necessities, one can primarily devote his time to the cultivation of Kṛṣṇa consciousness through the chanting of the holy names of God.
(Teachings of Lord Caitanya).

Sometimes ghosts and evil spirits appear in dreams and cause much perturbation; sometimes they appear as old women and suck the blood of small children, but they can not remain where there is chanting of the holy name of God.
(Krsna Book).

Of late, it has become a popular practise to publicly worship demigods with great pomp. All such worship is unauthorized, therefore intelligent people will follow the process of the congregational chanting of the holy names of God.
(Renunciation Through Wisdom).

Constant chanting of the holy name will make one free of offenses, and then he will gradually be elevated to the transcendental platform on which he can chant the pure holy name and thus become a lover of the Supreme Personality of Godhead.
It is recommended that even if one commits offenses, one should continue chanting the holy name. In other words, the chanting of the holy name makes one offenseless.
(Srimad Bhagavatam----7:5:23-24----purport).

Devotional service, which begins with chanting of the holy name of the Lord, is so powerful that even if one falls down from the exalted position of a brāhmaṇa through sexual indulgence, he can be saved from all calamities if he somehow or other chants the holy name of the Lord. This is the extraordinary power of the Lord's holy name.
(Srimad Bhagavatam----6:1:63----purport).

While chanting the holy name of the Lord, one should be careful to avoid ten offenses. From Sanat-kumāra it is understood that even if a person is a severe offender in many ways, he is freed from offensive life if he takes shelter of the Lord's holy name. Indeed, even if a human being is no better than a two-legged animal, he will be liberated if he takes shelter of the holy name of the Lord. One should therefore be very careful not to commit offenses at the lotus feet of the Lord's holy name.
(Srimad Bhagavatam----7:5:23-24----purport).

Even if one chants the holy name of the Lord with improper pronunciation, he will achieve relief from material bondage if he chants without offenses. Ajāmila, for example, was extremely sinful, but while dying he merely chanted the holy name, and although calling his son, he achieved complete liberation because he remembered the name of Nārāyaṇa.
(Srimad Bhagavatam----6:3:24----purport).

Everyone should be given the chance to hear the holy names of the Supreme Personality of Godhead, for thus one will gradually come to understand his real position in life and be elevated to the transcendental position above the mode of goodness. Thus all impediments to his progress will be cut to pieces.
(Srimad Bhagavatam----5:1:15----purport).

One must chant God's name, not, as the Māyāvādī philosophers say, any name, such as a demigod's name or the names of God's energies. Only the holy name of the Supreme Lord will be effective. Anyone who compares the holy name of the Supreme Lord to the names of the demigods is called pāṣaṇḍī, or an offender.
(Srimad Bhagavatam----3:33:7----purport).

Haridāsa Ṭhākura, although born in a mleccha or yavana family, became Nāmācārya Haridāsa Ṭhākura because he performed the nāma-yajña a minimum of 300,000 times every day
(Sri Caitanya Caritamrta----3:3:124---purport).

Haridāsa Ṭhākura, however, said that the desired result of chanting the holy name of the Lord is not that one is liberated from material bondage or freed from the reactions of sinful life. The actual result of chanting the holy name of the Lord is that one awakens his dormant Kṛṣṇa consciousness, his loving service to the Lord.
(Srimad Bhagavatam----5:24:20----purport).

The simple process of offenselessly chanting and hearing the holy name of the Lord will gradually promote one very soon to the stage of emancipation.
(Srimad Bhagavatam----2:2:30----purport).

The Lord's holy name is called śravaṇa-maṅgala. This means that one receives everything auspicious simply by hearing the holy name.
(Srimad Bhagavatam----2:7:15----purport).

This Vaikuṇṭha atmosphere is without fear and anxiety. One living entity does not fear another. By hearing the holy names and glories of the Lord, a person executes pious activities.
(Srimad Bhagavatam----4:30:35----purport).

Everyone should be given the chance to hear the holy names of the Supreme Personality of Godhead, for thus one will gradually come to understand his real position in life and be elevated to the transcendental position above the mode of goodness.
(Srimad Bhagavatam----5:1:15----purport).

By constantly chanting and hearing the holy names and pastimes of the Supreme Lord, one certainly becomes purified and becomes a fit candidate for liberation.
(Srimad Bhagavatam----5:8:31----purport).

One may very easily practice chanting and hearing the holy name of the Lord and thus become ecstatic in spiritual life.
(Srimad Bhagavatam----6:3:32----purport).

As stated in the Śrīmad-Bhāgavatam: simply by hearing the holy name of the Lord, one is immediately purified.
(Srimad Bhagavatam----6:16:44----purport).

The lowest of men, who are called caṇḍālas, are less than śūdras, but they also can be purified simply by hearing the holy name of the Lord, not to speak of personally seeing the Lord.
(Srimad Bhagavatam----6:16:44----purport).

Thinking of Kṛṣṇa, hearing the holy name of Kṛṣṇa or hearing the pastimes of Kṛṣṇa will make one pure, and then he will become a devotee.
(Srimad Bhagavatam----7:1:28-29----purport).

By hearing the holy name of the Lord, one comes to the platform of understanding the personal form of the Lord.
(Srimad Bhagavatam----7:5:23-24----purport).

The only method of controlling the senses is to chant and hear the holy name of the Lord; otherwise, one will always be disturbed, as a householder with more than one wife would be disturbed by them for sense gratification.
(Srimad Bhagavatam----7:9:40----purport).

A pure devotee who has been trained in the practice of chanting and hearing the holy name of the Lord and His fame, qualities, form, paraphernalia and so on is never interested in elevation to the heavenly planets, even though such places are extremely dear even to the demigods.
(Srimad Bhagavatam----9:4:24---purport).

Those who are already liberated chant and hear the holy name of the Lord, knowing perfectly that to glorify the Lord is the only way to keep oneself in a transcendental position.
(Srimad Bhagavatam----10:1:69----purport).

Animal hunters cannot enter into the transcendental pleasure of chanting and hearing the holy name of the Lord.
(Srimad Bhagavatam----10:1:69----purport).

While chanting and dancing or hearing the holy name of the Lord, one automatically remembers the Supreme Personality of Godhead, and because there is no difference between the holy name and Kṛṣṇa, the chanter is immediately linked with Kṛṣṇa.
(Sri Caitanya Caritamrta----1:7:83----purport).

As he read the thousand names of the Lord, in due course the holy name of Lord Nṛsiṁha appeared. When Caitanya Mahāprabhu heard the holy name of Lord Nṛsiṁha, He became fully absorbed in thought.
(Sri Caitanya Caritamrta----1:17:91----purport).

One may be the lowest of the low—a caṇḍāla, or dog-eater—but if he takes to chanting and hearing the holy name of the Lord, he is immediately eligible to perform Vedic sacrifices.
(Sri Caitanya Caritamrta----2:16:186----purport).

Unless one follows the spiritual master's instructions concerning the regulative principles and chanting and hearing the holy name of the Lord, one cannot become a pure devotee.
(Sri Caitanya Caritamrta----2:19:157----purport).

Śrīla Sanātana Gosvāmī has forbidden us to hear the holy name of Kṛṣṇa chanted by non-Vaiṣṇavas, such as professional actors and singers, for it will have no effect.
(Sri Caitanya Caritamrta----3:1:101----purport).

After sowing this seed, one has to water it in the form of chanting and hearing the holy name of the Supreme Lord or by taking part in discussions about the science of devotional service in a society of pure devotees.
(Teachings of Lord Caitanya).

By chanting and hearing the holy names of Kṛṣṇa, a person can remember the forms and qualities of Kṛṣṇa.
(Teachings of Lord Caitanya).

Those who are rich men in society should construct beautiful temples and arrange for the worship of Viṣṇu, so that people may be attracted to visit such temples and thereby be offered the opportunity of dancing before the Lord or chanting the holy name of the Lord, or else of hearing the holy name of the Lord.
(Nectar of Devotion).

If one only chants, with some slight faith, the holy names of Lord Caitanya and Nityānanda, very quickly he is cleansed of all offenses. Thus as soon as he chants the Hare Kṛṣṇa mahā-mantra, he feels the ecstasy of love for God.
(Sri Caitanya Caritamrta----1:8:31----translation).

Utterance of the holy name while one engages in sense gratification is an impediment on the path toward achieving ecstatic love for Kṛṣṇa. On the other hand, if one who is eager for devotional service utters the holy name even partially or improperly, the holy name, which is identical with the Supreme Personality of Godhead, exhibits its spiritual potency because of that person's offenseless utterance. Thus one is relieved from all unwanted practices, and one gradually awakens his dormant love for Kṛṣṇa.
(Sri Caitanya Caritamrta----3:5:59----purport).

If one who is embarrassed by hunger or who falls down or stumbles chants the holy name of the Lord even once, willingly or unwillingly, he is immediately freed from the reactions of his past deeds. Karmīs entangled in material activities face many difficulties in the practice of mystic yoga and other endeavors to achieve that same freedom.
(Srimad Bhagavatam----5:24:20----translation).

One who is not self-controlled and whose mind is not undisturbed cannot practice meditation. Therefore, in the Bṛhan-nāradīya Purāṇa it is said that in Kali-yuga (the present yuga, or age), when people in general are short-lived, slow in spiritual realization and always disturbed by various anxieties, the best means of spiritual realization is chanting the holy name of the Lord.
(Bhagavad-Gita----6:11-12----purport).

""In this age of quarrel and hypocrisy, the only means of deliverance is the chanting of the holy names of the Lord. There is no other way. There is no other way. There is no other way.""
(Sri Caitanya Caritamrta----2:6:242----translation).

Intelligent people will follow the process of the congregational chanting of the holy names of God and in this way worship Lord Gaurāṅga who is Kṛṣṇa Himself with a golden complexion. Worshiping Lord Kṛṣṇa is not an expensive affair, and worshiping Lord Caitanya is even easier and less expensive than worshiping Lord Kṛṣṇa.
(Renunciation Through Wisdom).

Kṛṣṇa consciousness is a very simple process. One need only chant the holy names of the Lord and strictly follow the principles forbidding sinful activity.
(Sri Caitanya Caritamrta----2:8:36----purport).

In the Caitanya-bhāgavata, Madhya-khaṇḍa, First Chapter, there is a statement about the method by which Lord Śrī Caitanya Mahāprabhu taught grammar. Lord Caitanya Mahāprabhu explained the aphorisms of grammar to be eternal, like the holy name of Kṛṣṇa.
(Sri Caitanya Caritamrta----1:13:29----purport).

Lord Caitanya never tried to be the master of the holy name; rather He taught us how to be servants of the holy name. If one chants the holy name of the Lord just to make a show, not knowing the secret of success, he may increase his bile secretion, but he will never attain perfection in chanting the holy name.
(Sri Caitanya Caritamrta----1:7:95-96----purport).

"'My dear Lord, when will My eyes be beautified by filling with tears that constantly glide down as I chant Your holy name? When will My voice falter and all the hairs on My body stand erect in transcendental happiness as I chant Your holy name?'"
(Sri Caitanya Caritamrta----3:20:36----translation).

The form of the Lord is beyond the jurisdiction of material form and is therefore inconceivable. A devotee prays, however, "My dear Lord, be pleased with me so that I may very easily see Your transcendental form and potency." Nondevotees try to understand the Supreme Brahman by discussions of neti neti. Niṣedha-nirvāṇa-sukhānubhūtiḥ: a devotee, however, simply by chanting the holy name of the Lord, avoids such laborious speculations and realizes the existence of the Lord very easily.
(Srimad Bhagavatam----6:4:27-28----purport).

three words oṁ tat sat are uttered in conjunction with the holy name of the Supreme Lord, e.g., oṁ tad viṣṇoḥ. Whenever a Vedic hymn or the holy name of the Supreme Lord is uttered, oṁ is added. This is the indication of Vedic literature.
(Bhagavad-Gita----17:23----purport).

It is an offense to preach the glories of the holy name among persons who have no intelligence or no faith in the subject matter. Such people should be given the chance to hear the chanting of the Hare Kṛṣṇa mantra, but in the beginning they should not be instructed about the glories or the spiritual significance of the holy name. By constant hearing of the holy name, their hearts will be purified, and then they will be able to understand the transcendental position of the holy name.
(Sri Caitanya Caitamrta----1:8:24----purport).

The Lord definitely says that no one is more dear to Him than one who is always engaged in the preaching work of the Lord's name and fame all over the world.
(Srimad Bhagavatam----1:5:36----purport).

In this age, when everything is polluted by the contamination of Kali, it is instructed in the scriptures andpreached by Lord Śrī Caitanya Mahāprabhu that by chanting the holy name of the Lord, we can at once be free from contamination and gradually rise to the status of transcendence and go back to Godhead.
(Srimad Bhagavatam----1:16:32-33----purport).

The name Kṛṣṇa appears with both Lord Kṛṣṇa and Lord Caitanya Kṛṣṇa. Lord Śrī Caitanya Mahāprabhu is the Supreme Personality of Godhead, but He always engages in describing Kṛṣṇa and thus enjoys transcendental bliss by chanting and remembering His name and form. Lord Kṛṣṇa Himself appears as Lord Caitanya to preach the highest gospel.
(Sri Caitanya Caitamrta----1:3:52----purport).

Kṛṣṇadāsa Kavirāja Gosvāmī explains, kṛṣṇa-śakti vinā nahe tāra pravartana: unless one receives special power of attorney from the Supreme Personality of Godhead, he cannot preach the glories of the Hare Kṛṣṇa mahā-mantra. As devotees propagate the Hare Kṛṣṇa mahā-mantra, the general population of the entire world gets the opportunity to understand the glories of the holy name. While chanting and dancing or hearing the holy name of the Lord, one automatically remembers the Supreme Personality of Godhead, and because there is no difference between the holy name and Kṛṣṇa, the chanter is immediately linked with Kṛṣṇa.
(Sri Caitanya Caitamrta----1:7:83----purport).

At the beginning of every function in preaching, especially before chanting the Hare Kṛṣṇa mahā-mantra—Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare—we must chant the Pañca-tattva's names and offer our respects to them.
(Sri Caitanya Caitamrta----1:8:4----purport).

The Kṛṣṇa consciousness devotees must always desire to remain in the society of devotees. Bhakta-sane vāsa: they cannot go outside the Kṛṣṇa consciousness society or movement. Within the society we must try to serve the predecessors by preaching Caitanya Mahāprabhu's cult and spreading His name and fame all over the world. If we attempt this seriously within the society, it will be successfully done. There is no question of estimating how this will happen in the mundane sense. But without a doubt, it happens by the grace of Kṛṣṇa.
(Sri Caitanya Caitamrta----2:4:79----purport).

One cannot become an ācārya simply by mental speculation. The true ācārya presents Kṛṣṇa to everyone by preaching the holy name of the Lord throughout the world. Thus the conditioned souls, purified by chanting the holy name, are liberated from the blazing fire of material existence. In this way, spiritual benefit grows increasingly full, like the waxing moon in the sky. The true ācārya, the spiritual master of the entire world, must be considered an incarnation of Kṛṣṇa's mercy.
(Sri Caitanya Caitamrta----3:7:12----purport).

For iron to be attracted by a magnet is natural. Similarly, for all living entities to be attracted toward Kṛṣṇa is natural, and therefore the Lord's real name is Kṛṣṇa, meaning He who attracts everyone and everything. The typical examples of such attraction are found in Vṛndāvana, where everything and everyone is attracted by Kṛṣṇa. The elderly persons like Nanda Mahārāja and Yaśodādevī, the friends like Śrīdāmā, Sudāmā and the other cowherd boys, the gopīs like Śrīmatī Rādhārāṇī and Her associates, and even the birds, beasts, cows and calves are attracted. The flowers and fruits in the gardens are attracted, the waves of the Yamunā are attracted, and the land, sky, trees, plants, animals and all other living beings are attracted by Kṛṣṇa. This is the natural situation of everything in Vṛndāvana.
(Srimad Bhagavatam----7:5:14----purport).

The demons are not clean, either externally or internally. One should always be careful to keep his body clean by bathing, brushing teeth, shaving, changing clothes, etc. As far as internal cleanliness is concerned, one should always remember the holy names of God and chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. The demons neither like nor follow all these rules for external and internal cleanliness.
(Bhagavad-Gita----16:7----purport).

The only business is to chant and remember the holy name, fame and pastimes of the Lord and, according to personal capacity, to distribute the message for others' welfare without motive of material gain.
(Srimad Bhagavatam----1:6:26----purport).

Ajāmila remembered the holy name of the Lord, Nārāyaṇa, by merely calling the name of his son Nārāyaṇa, and that gave him a complete opportunity to achieve the highest perfection of life.
(Srimad Bhagavatam----3:9:15----purport).

The real success in life is ante nārāyaṇa-smṛti—remembering the holy name, attributes, activities and form of the Lord at the time of death. Although we may be engaged in the Lord's devotional service in the temple, material conditions are so tough and inevitable that we may forget the Lord at the time of death due to a diseased condition or mental derangement. Therefore we should pray to the Lord to be able to remember His lotus feet without fail at the time of death, when we are in such a precarious condition.
(Srimad Bhagavatam----5:3:12----purport).

The process of devotional service entails hearing, chanting and remembering the holy name, form, pastimes, qualities and entourage of the Lord, offering service according to the time, place and performer, worshiping the Deity, offering prayers, always considering oneself the eternal servant of Kṛṣṇa, making friends with Him and dedicating everything unto Him.
(Sri Caitanya Caritamrta----2:15:107----purport).

One may be a sinful man before chanting the holy name of the Lord, but after taking shelter in the holy name of the Lord and becoming immune, one should strictly restrain oneself from committing sinful acts with a hope that his method of chanting the holy name will give him protection.
(Srimad Bhagavatam----2:1:11----purport).

One who has taken shelter of the holy name of the Lord, which is identical with the Lord, does not have to study Vedānta philosophy, for he has already completed all such study.
(Sri Caitanya Caritamrta----1:7:72----purport).

A well-to-do householder Vaiṣṇava cannot live like a person in the renounced order who completely takes shelter of the holy name. Such a householder should chant the holy name of Kṛṣṇa in the morning, at midday and in the evening.
(Sri Caitanya Caritamrta----3:6:223----purport).

The more one is freed from material identification, the more one can realize that the spirit soul is qualitatively as good as the Supreme Soul. At such a time, when one is situated on the absolute platform, one can understand that the holy name of the Lord and the Lord Himself are identical. At that stage of realization, the holy name of the Lord, the Hare Kṛṣṇa mantra, cannot be identified with any material sound. If one accepts the Hare Kṛṣṇa mahā-mantra as a material vibration, he falls down. One should worship and chant the holy name of the Lord by accepting it as the Lord Himself. One should therefore be initiated properly according to revealed scriptures under the direction of a bona fide spiritual master. Although chanting the holy name is good for both the conditioned and liberated soul, it is especially beneficial to the conditioned soul because by chanting it one is liberated. When a person who chants the holy name is liberated, he attains the ultimate perfection by returning home, back to Godhead.
(Sri Caitanya Caritamrta----2:15:108----purport).

The holy name and the Lord are identical. One who is completely free from the clutches of māyā can understand this fact. This knowledge, which is achieved by the mercy of the spiritual master, places one on the supreme transcendental platform. Śrī Caitanya Mahāprabhu presented Himself as a fool because prior to accepting the shelter of a spiritual master He could not understand that simply by chanting one can be relieved from all material conditions. But as soon as He became a faithful servant of His spiritual master and followed his instructions, He very easily saw the path of liberation. Śrī Caitanya Mahāprabhu's chanting of the Hare Kṛṣṇa mantra must be understood to be devoid of all offenses. The ten offenses against the holy name are as follows: (1) to blaspheme a devotee of the Lord, (2) to consider the Lord and the demigods to be on the same level or to think that there are many gods, (3) to neglect the orders of the spiritual master, (4) to minimize the authority of scriptures (Vedas), (5) to interpret the holy name of God, (6) to commit sins on the strength of chanting, (7) to instruct the glories of the Lord's name to the unfaithful, (8) to compare the chanting of the holy name with material piety, (9) to be inattentive while chanting the holy name, and (10) to be attached to material things in spite of chanting the holy name.
(Sri Caitanya Caritamrta----1:7:73----purport).

“"The holy name of Kṛṣṇa is transcendentally blissful. It bestows all spiritual benedictions, for it is Kṛṣṇa Himself, the reservoir of all pleasure. Kṛṣṇa"s name is complete, and it is the form of all transcendental mellows. It is not a material name under any condition, and it is no less powerful than Kṛṣṇa Himself. Since Kṛṣṇa's name is not contaminated by the material qualities, there is no question of its being involved with māyā. Kṛṣṇa's name is always liberated and spiritual; it is never conditioned by the laws of material nature. This is because the name of Kṛṣṇa and Kṛṣṇa Himself are identical.’
(Sri Caitanya Caritamrta----2:17:133----translation).

The holy name, character, pastimes and activities of Kṛṣṇa are all transcendentally sweet like sugar candy. Although the tongue of one afflicted by the jaundice of avidyā (ignorance) cannot taste anything sweet, it is wonderful that simply by carefully chanting these sweet names every day, a natural relish awakens within his tongue, and his disease is gradually destroyed at the root.
(Nectar of Instruction).

The powerful holy name of the Lord can certainly deliver one from sinful effects, but one who desires to utilize this transcendental potency of the holy name of the Lord in one's sinister activities is the most degraded person in the world. Such persons are never excused by the Lord or by any agent of the Lord.
(Srimad Bhagavatam----2:1:12----purport).
