I offer my respectful obeisances unto all the Vaiṣṇava devotees of the Lord. They can fulfill the desires of everyone, just like desire trees, and they are full of compassion for the fallen souls.
(Bhagavad-Gita--introduction).

I offer my respectful obeisances unto the lotus feet of my spiritual master and unto the feet of all Vaiṣṇavas. I offer my respectful obeisances unto the lotus feet of Śrīla Rūpa Gosvāmī along with his elder brother Sanātana Gosvāmī, as well as Raghunātha Dāsa and Raghunātha Bhaṭṭa, Gopāla Bhaṭṭa, and Śrīla Jīva Gosvāmī. I offer my respectful obeisances to Lord Kṛṣṇa Caitanya and Lord Nityānanda along with Advaita Ācārya, Gadādhara, Śrīvāsa, and other associates. I offer my respectful obeisances to Śrīmatī Rādhārāṇī and Śrī Kṛṣṇa along with Their associates Śrī Lalitā and Viśākhā.
(Bhagavad-Gita--introduction).

One should not become falsely proud. One must be respectful toward a person more elevated than he by birth, education, behavior, caste or spiritual order. If one does not show respect to such highly elevated persons but indulges in false pride, he receives punishment in Kṣārakardama.
(Srimad Bhagavatam-----5:26:30-----purport).

Brahmājī confirms herewith that only persons who have developed the desirable qualities can enter into the kingdom of God. In the Caitanya-caritāmṛta, the devotee's desirable qualities are described to be twenty-six in number. They are stated as follows: He is very kind; he does not quarrel with anyone; he accepts Kṛṣṇa consciousness as the highest goal of life; he is equal to everyone; no one can find fault in his character; he is magnanimous, mild and always clean, internally and externally; he does not profess to possess anything in this material world; he is a benefactor to all living entities; he is peaceful and is a soul completely surrendered to Kṛṣṇa; he has no material desire to fulfill; he is meek and humble, always steady, and has conquered the sensual activities; he does not eat more than required to maintain body and soul together; he is never mad after material identity; he isrespectful to all others and does not demand respect for himself; he is very grave, very compassionate and very friendly; he is poetic; he is expert in all activities, and he is silent in nonsense.
(Srimad Bhagavatam-----3:15:25-----purport).

When Kṛṣṇa was on this planet, He set a practical example. He was a cowherd boy, and He was very respectful to the brāhmaṇas and devotees.
(Srimad Bhagavatam-----3:16:23-----purport).

Śrī Maitreya said: Devahūti was fully faithful and respectful toward the direction of her husband, Kardama, who was one of the Prajāpatis, or generators of human beings in the universe. O great sage, she thus began to worship the master of the universe, the Supreme Personality of Godhead, who is situated in everyone's heart.
(Srimad Bhagavatam-----3:24:5-----purport).

Lord Śiva is described herein as the best of all great souls. Although Satī's body was born of Dakṣa, Lord Śiva used to adore her by sitting her on his lap. This is considered a great token of respect. Thus Satī's body was not ordinary, but still she decided to give it up because it was the source of unhappiness because of its connection with Dakṣa. This severe example set by Satī is to be followed. One should be extremely careful about associating with persons who are not respectful to the higher authorities.
(Srimad Bhagavatam-----4:4:26-----purport).

The word anātmya is significant. Ātmya means "the life of the soul," so this word indicates that although Dakṣa appeared to be living, actually he was a dead body, otherwise how could he neglect Satī, who was his own daughter? It was the duty of Dakṣa to look after the maintenance and comforts of all living entities because he was situated as Prajāpati, the governor of all living entities. Therefore how is it that he neglected his own daughter, who was the most exalted and chaste woman, a great soul, and who therefore deserved the most respectful treatment from her father? The death of Satī because of her being neglected by Dakṣa, her father, was most astonishing to all the great demigods of the universe.
(Srimad Bhagavatam-----4:4:29-----purport).

A Vaiṣṇava is always respectful to everyone.
(Srimad Bhagavatam-----4:12:9-----purport).

The four Kumāras are paramparā spiritual masters of the Vaiṣṇava sampradāya. Out of the four sampradāyas, namely Brahma-sampradāya, Śrī-sampradāya, Kumāra-sampradāya and Rudra-sampradāya, the disciplic succession of spiritual master to disciple known as the Kumāra-sampradāya is coming down from the four Kumāras. So Pṛthu Mahārāja was very respectful to the sampradāya-ācāryas.
(Srimad Bhagavatam-----4:22:4-----purport).

One may engage in any business—material or spiritual—but the purpose should be the satisfaction of the Supreme Personality of Godhead. This verse presents a perfect picture of Vedic civilization. People training to become devotees should be respectful not only to the Supreme Personality of Godhead but also to those who are elderly in knowledge, who are Āryans and actual devotees of the Lord.
(Srimad Bhagavatam-----4:30:39-40-----purport).

This chapter describes how all the planetary systems take shelter of the polestar, Dhruvaloka. It also describes the totality of these planetary systems to be Śiśumāra, another expansion of the external body of the Supreme Personality of Godhead. Dhruvaloka, the abode of Lord Viṣṇu within this universe, is situated 1,300,000 yojanas from the seven stars. In the planetary system of Dhruvaloka are the planets of the fire-god, Indra, Prajāpati, Kaśyapa and Dharma, all of whom are very respectful to the great devotee Dhruva, who lives on the polestar.
(Srimad Bhagavatam-----5:23--summary).

Deity worship is especially meant for purifying the neophyte devotees. Actually, however, preaching is more important. In Bhagavad-gītā (18.69) it is said, na ca tasmān manuṣyeṣu kaścin me priya-kṛttamaḥ: if one wants to be recognized by the Supreme Personality of Godhead, he must preach the glories of the Lord. One who worships the Deity must therefore be extremely respectful to preachers; otherwise simply worshiping the Deity will keep one in the lower stage of devotion.
(Srimad Bhagavatam-----7:14:40-----purport).

After Lord Śiva drank all the poison, both the demigods and demons took courage and resumed their activities of churning. Because of this churning, first a surabhi cow was produced. Great saintly persons accepted this cow to derive clarified butter from its milk and offer this clarified butter in oblations for great sacrifices. Thereafter, a horse named Uccaiḥśravā was generated. This horse was taken by Bali Mahārāja. Then there appeared Airāvata and other elephants that could go anywhere in any direction, and she-elephants also appeared. The gem known as Kaustubha was also generated, and Lord Viṣṇu took that gem and placed it on His chest. Thereafter, a pārijāta flower and the Apsarās, the most beautiful women in the universe, were generated. Then the goddess of fortune, Lakṣmī, appeared. The demigods, great sages, Gandharvas and others offered her their respectful worship.
(Srimad Bhagavatam-----8:8--summary).

Once Mahārāja Ambarīṣa was worshiping the Supreme Personality of Godhead in Vṛndāvana, observing the vow of Dvādaśī. On Dvādaśī, the day after Ekādaśī, when he was about to break his Ekādaśī fast, the great mystic yogī Durvāsā appeared in his house and became his guest. King Ambarīṣa respectfully received Durvāsā Muni, and Durvāsā Muni, after accepting his invitation to eat there, went to bathe in the Yamunā River at noontime.
(Srimad Bhagavatam-----9:4--summary).

Mother Ganges is available to everyone for bathing. Therefore, not only will sinful persons bathe in the Ganges water, but in Hardwar and other holy places where the Ganges flows, saintly persons and devotees will also bathe in the waters of the Ganges. Devotees and saintly persons advanced in the renounced order can deliver even the Ganges. Tīrthī-kurvanti tīrthāni svāntaḥ-sthena gadābhṛtā (S.B.1:13:10). Because saintly devotees always keep the Lord within the core of their hearts, they can perfectly cleanse the holy places of all sinful reactions. Therefore, people in general must always respectfully honor saintly persons. It is ordered that as soon as one sees a Vaiṣṇava, or even a sannyāsī, one should immediately offer respects to such a holy man. If one forgets to show respect in this way, one must observe a fast for that day. This is a Vedic injunction. One must be extremely careful to refrain from committing offenses at the lotus feet of a devotee or saintly person.
(Srimad Bhagavatam-----9:9:6-----purport).

By offering His obeisances to the Māyāvādī sannyāsīs, Śrī Caitanya Mahāprabhu very clearly exhibited His humbleness to everyone. Vaiṣṇavas must not be disrespectful to anyone, to say nothing of a sannyāsī. Śrī Caitanya Mahāprabhu teaches, amāninā māna-dena: one should always be respectful to others but should not demand respect for himself.
(Sri Caitanya Caritamrta----1:7:59----purport).

The respectful behavior of Prakāśānanda Sarasvatī toward Śrī Caitanya Mahāprabhu is very much to be appreciated. Such behavior is calculated to be ajñāta-sukṛti, or pious activities that one executes unknowingly. Thus Śrī Caitanya Mahāprabhu very tactfully gave Prakāśānanda Sarasvatī an opportunity to advance in ajñāta-sukṛti so that in the future he might actually become a Vaiṣṇava sannyāsī.
(Sri Caitanya Caritamrta----1:7:65----purport).

Anyone who is a bona fide preacher of the cult of Śrī Caitanya Mahāprabhu must be respectful to the real devotees of Lord Caitanya; one should not be envious, considering one preacher to be very great and another to be very lowly. This is a material distinction and has no place on the platform of spiritual activities. Kṛṣṇadāsa Kavirāja Gosvāmī therefore offers equal respect to all the preachers of the cult of Śrī Caitanya Mahāprabhu, who are compared to the branches of the tree. ISKCON is one of these branches, and it should therefore be respected by all sincere devotees of Lord Caitanya Mahāprabhu.
(Sri Caitanya Caritamrta----1:10:7----purport).

Śrī Caitanya Mahāprabhu went to Gayā to offer respectful oblations to His forefathers. This process is called piṇḍa-dāna. In Vedic society, after the death of a relative, especially one's father or mother, one must go to Gayā and there offer oblations to the lotus feet of Lord Viṣṇu. Therefore hundreds and thousands of men gather in Gayā daily to offer such oblations, or śrāddha. Following this principle, Lord Caitanya Mahāprabhu also went there to offer piṇḍa to His dead father. Fortunately He met Īśvara Purī there.
(Sri Caitanya Caritamrta----1:17:8----purport).

As long as loving service is rendered to the Lord in the master-servant relationship, there is some fear, for the servant is always afraid of the master, despite the intimacy of self-interest. In this stage the servant is always afraid of the master and respectful of Him. When the devotee is further advanced, he has nothing to fear. He considers the Lord and himself on an equal level. At such a time, the devotee is fully convinced that Lord Kṛṣṇa is a friend and cannot at all be dissatisfied if the devotee lives with Him on an equal level. This understanding is called viśrambha, that is, devoid of a respectful attitude. When this attitude is chosen, it becomes sakhya-prema, or love of Godhead in friendship. On this stage there is developed consciousness of equality between the Lord and the devotee.
(Sri Caitanya Caritamrta----2:8:74----purport).

When a devotee, in spite of possessing all the qualities of pure realization, is not proud of his position, he is called prideless. In the Padma Purāṇa it is stated that King Bhagīratha was the emperor above all other kings, yet he developed such ecstatic love for Kṛṣṇa that he became a mendicant and went out begging even to the homes of his political enemies and untouchables. He was so humble that he respectfully bowed down before them.
(Nectar of Devotion).

Once when Kṛṣṇa and His cowherd friends were enjoying friendly conversation, Kṛṣṇa began to address His associates in casual language. At that time Kṛṣṇa's servant Patrī was also enjoying the conversation. But then, remembering his position of servitude, Patrī bowed down before his master, and with great respect and control, he stifled his smiling. This subdued smiling is an instance of concealment caused by a respectful attitude.
(Nectar of Devotion).

Arjuna embraced Kṛṣṇa as a friend of the same age, whereas the two younger brothers, namely Nakula and Sahadeva, touched the lotus feet of Kṛṣṇa to show Him respect. After an exchange of greetings according to the social etiquette befitting the position of the Pāṇḍavas and Lord Kṛṣṇa, Kṛṣṇa was offered an exalted seat. When He was comfortably seated, the newly married Draupadī, young and very beautiful in her natural feminine gracefulness, came before Lord Kṛṣṇa to offer her respectful greetings. The Yādavas who accompanied Kṛṣṇa to Hastināpura were also very respectfully received; specifically, Sātyaki, or Yuyudhāna, was also offered a nice seat. In this way, when everyone else was properly seated, the five brothers took their seats near Lord Kṛṣṇa.
(Krsna Book).

After rising from bed the next morning, Śrī Caitanya Mahāprabhu visited the local temple, where there was a deity of Hanumān. After offering him obeisances, the Lord departed for South India.
In almost all the cities and towns of India there are temples of Hanumānjī, the eternal servant of Lord Rāmacandra. There is even a temple of Hanumān near Govindajī temple in Vṛndāvana. Formerly this temple was in front of the Gopālajī temple, but the Gopālajī Deity went to Orissa to remain as Sākṣi-gopāla. Being the eternal servant of Lord Rāmacandra, Hanumānjī has been respectfully worshiped for many hundreds and thousands of years. Here even Lord Śrī Caitanya Mahāprabhu set the example in showing how one should offer respects to Hanumānjī.
(Sri Caitanya Caritamrta----2:8:300----purport).

One should be extremely careful about associating with persons who are not respectful to the higher authorities. It is instructed, therefore, in the Vedic literature that one should always be free from the association of atheists and nondevotees and should try to associate with devotees, for by the association of a devotee one can be elevated to the platform of self-realization.
(Srimad Bhagavatam-----4:4:26-----purport).

People will be surprised that Lord Buddha is designated as atheist and still the Vaiṣṇavas, they are offering their respectful prayers to Lord Viṣṇu (Buddha). Why? Because the Vaiṣṇava knows how the God is acting for His different purposes. Others, they do not know.
(Lecture-- Dasavatara-stotra purport).

We offer our respectful obeisances to Vaiṣṇava because Vaiṣṇava is meant for delivering the fallen souls. That is Vaiṣṇava's business. They have taken so much trouble just to deliver the fallen souls from the sinful activities, and those who are being punished, to save them, this is Vaiṣṇava's business.
(Lecture on Srimad Bhagavatam--6:1:6).

The secret of success in spiritual life is in satisfying the spiritual master and thereby getting his sincere blessings. Śrīla Viśvanātha Cakravartī Ṭhākura has sung in his famous eight stanzas on the spiritual master as follows: "I offer my respectful obeisances unto the lotus feet of my spiritual master. Only by his satisfaction can one please the Personality of Godhead, and when he is dissatisfied there is only havoc on the path of spiritual realization." It is essential, therefore, that a disciple be very much obedient and submissive to the bona fide spiritual master.
(Srimad Bhagavatam----1:1:8----purport).

Śrī Caitanya Mahāprabhu accepted this principle and recognized Śrīla Haridāsa Ṭhākura as the ācārya of the holy name, although Ṭhākura Haridāsa appeared in a Mohammedan family. In conclusion, Śrīla Śukadeva Gosvāmī was born a Vaiṣṇava, and, therefore, brahminism was included in him. He did not have to undergo any ceremonies. Any lowborn person—be he a Kirāta, Hūṇa, Āndhra, Pulinda, Pulkaśa, Ābhīra, Śumbha, Yavana, Khasa or even lower—can be delivered to the highest transcendental position by the mercy of Vaiṣṇavas. Śrīla Śukadeva Gosvāmī was the spiritual master of Śrī Sūta Gosvāmī, who therefore offers his respectful obeisances unto Śrīla Śukadeva Gosvāmī before he begins his answers to the questions of the sages at Naimiṣāraṇya.
(Srimad Bhagavatam----1:2:2----purport).

Although Lord Brahmā had received very respectful obeisances from Lord Śiva, he knew that Lord Śiva was in a more exalted position than himself. Lord Śiva's position is described in Brahma-saṁhitā: there is no difference between Lord Viṣṇu and Lord Śiva in their original positions, but still Lord Śiva is different from Lord Viṣṇu. The example is given that the milk in yogurt is not different from the original milk from which it was made.
(Srimad Bhagavatam----4:6:42----purport).

It appears that Lord Viṣṇu is the Supreme Lord even of Lord Śiva and Lord Brahmā, what to speak of the demigods, Gandharvas and ordinary living entities. It is stated in a prayer, yaṁ brahmā varuṇendra-rudra-marutāḥ: all the demigods worship Lord Viṣṇu. Similarly, dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ: (SB 12.13.1) yogīs concentrate their minds on the form of Lord Viṣṇu. Thus Lord Viṣṇu is worshipable by all demigods, all Gandharvas and even Lord Śiva and Lord Brahmā. Tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti sūrayaḥ: Viṣṇu is therefore the Supreme Personality of Godhead. Even though Lord Śiva was previously referred to in prayers by Lord Brahmā as the Supreme, when Lord Viṣṇu appeared, Śiva also fell prostrated before Him to offer respectful obeisances.
(Srimad Bhagavatam----4:7:22----purport).

Prahlāda Mahārāja is the topmost example of a Vaiṣṇava, who is always compassionate toward sinful persons suffering a hellish life within this material world. Kṛṣṇa is therefore known as para-duḥkha-duḥkhī kṛpāmbudhiḥ, or one who is compassionate toward others' suffering and who is an ocean of mercy. Like Prahlāda Mahārāja, all pure devotees of the Lord come to this material world with full compassion to deliver the sinful. They undergo all kinds of tribulations, suffering them with tolerance, because that is another qualification of a Vaiṣṇava, who tries to deliver all sinful persons from the hellish conditions of material existence. Vaiṣṇavas are therefore offered the following prayer:
vāñchā-kalpatarubhyaś ca
kṛpā-sindhubhya eva ca
patitānāṁ pāvanebhyo
vaiṣṇavebhyo namo namaḥ
(I offer my respectful obeisances unto all the Vaiṣṇava devotees of the Lord. They can fulfill the desires of everyone, just like desire trees, and they are full of compassion for the fallen souls.)
The chief concern of a Vaiṣṇava is to deliver the fallen souls.
(Srimad Bhagavatam----4:21:47----purport).

The form of the Lord as worshiped in the temples is called arca-vigraha or arcāvatāra, the worshipable form, the Deity incarnation. This facility is offered to neophyte devotees so that they can see the real form of the Lord face to face and offer their respectful obeisances and sacrifices in the form of arcā. Through such facilities the neophytes gradually invoke their original Kṛṣṇa consciousness. Deity worship in the form of temple worship is the most valuable benediction given by the Lord to beginners. All neophytes must therefore engage in the worship of the Lord by keeping the arcā-vigraha (arcāvatāra) at home or in the temple.
(Srimad Bhagavatam----4:30:27----purport).

When a saintly person wants to see his kinsmen, he has no material desire to see them. He simply wants to give them some instructions so that they can benefit. Vidura belonged to the royal family of the Kauravas, and although he knew that all the family members were destroyed at the Battle of Kurukṣetra, he nonetheless wanted to see his elder brother, Dhṛtarāṣṭra, to see if he could deliver Dhṛtarāṣṭra from the clutches of māyā. When a great saintly person like Vidura sees his relatives, he desires only to deliver them from the clutches of māyā. Vidura thus offered his respectful obeisances to his spiritual master and departed for the city of Hastināpura, the kingdom of the Kauravas.
(Srimad Bhagavatam----4:31:30----purport).

Yamarāja has specifically described the qualities of the Viṣṇudūtas to convince his own servants not to be envious of them. Yamarāja warned the Yamadūtas that the Viṣṇudūtas are worshiped with respectful obeisances by the demigods and are always very alert to protect the devotees of the Lord from the hands of enemies, from natural disturbances and from all dangerous conditions in this material world.
(Srimad Bhagavatam----4:3:18----purport).

Śrīla Viśvanātha Cakravartī Ṭhākura says in this regard that when a president or king is sitting on his throne, he does not need to show respect to everyone who comes within his assembly, but he must show respect to superiors like his spiritual master, brāhmaṇas and Vaiṣṇavas. There are many examples of how he should act. When Lord Kṛṣṇa was sitting on His throne and Nārada fortunately entered His assembly, even Lord Kṛṣṇa immediately stood up with His officers and ministers to offer respectful obeisances to Nārada. Nārada knew that Kṛṣṇa is the Supreme Personality of Godhead, and Kṛṣṇa knew that Nārada was His devotee, but although Kṛṣṇa is the Supreme Lord and Nārada is the Lord's devotee, the Lord observed the religious etiquette. Since Nārada was a brahmacārī, a brāhmaṇa and an exalted devotee, even Kṛṣṇa, while acting as a king, offered His respectful obeisances unto Nārada.
(Srimad Bhagavatam----4:7:13----purport).

If one desires he can subdue all the material activities of his senses, and the Lord, by manifesting His spiritual energy, can reveal Himself to the pure devotee. When the Supreme Personality of Godhead reveals Himself to the pure devotee, the devotee has no other duty than to offer Him respectful obeisances.
(Srimad Bhagavatam----4:3:23----purport).
