"Perspiration, trembling, standing on end of one"s bodily hairs, tears, faltering voice, fading complexion, madness, melancholy, patience, pride, joy and humility—these are various natural symptoms of ecstatic love of Godhead, which causes a devotee to dance and float in an ocean of transcendental bliss while chanting the Hare Kṛṣṇa mantra.
(Sri Caitanya Caritamrta------1:7:89-90------translation).

"My dear Lord, I have no problems and want no benediction from You because I am quite satisfied to chant Your holy name. This is sufficient for me because whenever I chant I immediately merge in an ocean of transcendental bliss. I only lament to see others bereft of Your love. They are rotting in material activities for transient material pleasure and spoiling their lives toiling all day and night simply for sense gratification, with no attachment for love of Godhead. I am simply lamenting for them and devising various plans to deliver them from the clutches of māyā."
(Sri Caitanya Caritamrta------1:7:92------purport).

“Compared to the ocean of transcendental bliss that one tastes by chanting the Hare Kṛṣṇa mantra, the pleasure derived from impersonal Brahman realization (brahmānanda) is like the shallow water in a canal.
In the Bhakti-rasāmṛta-sindhu (1.1.38) it is stated:
brahmānando bhaved eṣa cet parārdha-guṇī-kṛtaḥ
naiti bhakti-sukhāmbhodheḥ paramāṇu-tulām api
"If brahmānanda, the transcendental bliss derived from understanding impersonal Brahman, were multiplied a million times, such a quantity of brahmānanda could not compare with even an atomic portion of the pleasure relished in pure devotional service."
(Sri Caitanya Caritamrta------1:7:97------translation and purport).

The brāhmaṇa begged Lord Caitanya Mahāprabhu, "My dear Lord, kindly show me favor and let me go with You. I can no longer tolerate the waves of misery caused by materialistic life."
This statement is applicable for everyone, regardless of how rich or prosperous one may be. Narottama dāsa Ṭhākura has confirmed this statement: saṁsāra-viṣānale, divā-niśi hiyā jvale. He states that the materialistic way of life causes a burning in the heart. One cannot make any provisions for the troublesome life of the material world. It is a fact that one may be very happy as far as riches are concerned and one may be very opulent in every respect, yet one has to manage the viṣayas to meet the demands of the body and of so many family members and subordinates. One has to take so much trouble to minister to others. Narottama dāsa Ṭhākura therefore prays: viṣaya chāḍiyā kabe śuddha ha’be mana. Thus one must become freed from the materialistic way of life. One has to merge himself in the ocean of transcendental bliss. In other words, one cannot relish transcendental bliss without being freed from the materialistic way of life. It appears that the brāhmaṇa named Kūrma was materially very happy, for he expressed his family tradition as janma-kula-dhana. Now, being glorious, he wanted to leave all these material opulences. He wanted to travel with Śrī Caitanya Mahāprabhu. According to the Vedic way of civilization, one should leave his family after attaining fifty years of age and go to the forest of Vṛndāvana to devote the rest of his life to the service of the Lord.
(Sri Caitanya Caritamrta------2:7:126------translation and purport).

Glory to the Śrī Kṛṣṇa saṅkīrtana, which cleanses the heart of all the dust accumulated for years and extinguishes the fire of conditional life, of repeated birth and death. This saṅkīrtana movement is the prime benediction for humanity at large because it spreads the rays of the benediction moon. It is the life of all transcendental knowledge. It increases the ocean of transcendental bliss, and it enables us to fully taste the nectar for which we are always anxious.
(Teachings of Lord Caitanya).

A similar verse is found in the Eighth Canto, Third Chapter, of Śrīmad-Bhāgavatam, verse 20. Gajendra says there, "My dear Lord, I have no experience of the transcendental bliss derived from Your devotional service, so therefore I have asked from You some favor. But I know that persons who are pure devotees and have, by serving the lotus feet of great souls, become freed from all material desires, are always merged in the ocean of transcendental bliss and, as such, are always satisfied simply by glorifying Your auspicious characteristics. For them there is nothing else to aspire to or pray for."
(Nectar of Devotion).

"All glories to the Śrī Kṛṣṇa saṅkīrtana, which cleanses the heart of all the dust accumulated for years and extinguishes the fire of conditional life, of repeated birth and death. This saṅkīrtana movement is the prime benediction for humanity at large because it spreads the rays of the benediction moon. It is the life of all transcendental knowledge. It increases the ocean of transcendental bliss, and it enables us to fully taste the nectar for which we are always anxious."
Not only is the chanter of the mahā-mantra purified, but the heart of anyone who happens to hear the transcendental vibration of Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare is also cleansed. Even the souls embodied in lower animals, insects, trees and other species of life also become purified and prepared to become fully Kṛṣṇa conscious simply by hearing the transcendental vibration.
(Nectar of Instruction).

(Srimad Bhagavatam------introduction).

"If brahmānanda, the bliss of merging in the Brahman effulgence, were multiplied one hundred trillion times, it would still not equal even an atomic fragment of the ocean of transcendental bliss felt in devotional service."
(Srimad Bhagavatam-------7:7:37------purport).

Unalloyed devotees, who have no desire other than to serve the Lord, worship Him in full surrender and always hear and chant about His activities, which are most wonderful and auspicious. Thus they always merge in an ocean of transcendental bliss. Such devotees never ask the Lord for any benediction. I, however, am in danger. Thus I pray to that Supreme Personality of Godhead, who is eternally existing, who is invisible, who is the Lord of all great personalities, such as Brahmā, and who is available only by transcendental bhakti-yoga. Being extremely subtle, He is beyond the reach of my senses and transcendental to all external realization. He is unlimited, He is the original cause, and He is completely full in everything. I offer my obeisances unto Him.
(Srimad Bhagavatam-------8:3:20-21------translation).

Lord Brahmā said: Although You are never born, Your appearance and disappearance as an incarnation never cease. You are always free from the material qualities, and You are the shelter of transcendental bliss resembling an ocean. Eternally existing in Your transcendental form, You are the supreme subtle of the most extremely subtle. We therefore offer our respectful obeisances unto You, the Supreme, whose existence is inconceivable.
(Srimad Bhagavatam-------8:6:8------translation).

A devotee is always merged in the ocean of the transcendental bliss of rendering service to the Lord. Therefore he is not at all afraid of any adverse situation in the material world. The Lord also promises, kaunteya pratijānīhi na me bhaktaḥ praṇaśyati: "O Arjuna, you may declare to the world that the devotees of the Lord are never vanquished." For the protection of the devotees, Kṛṣṇa's disc, the Sudarśana cakra, is always ready. This disc is extremely fearful to the nondevotees (pratyanīka-bhayāvaham). Therefore although Mahārāja Ambarīṣa was fully engaged in devotional service, his kingdom was free of all fear of adversity.
(Srimad Bhagavatam-------9:4:28------purport).

As a fatigued man feels refreshed by dipping into a reservoir of water, so the conditioned soul who is very much disgusted with material activities becomes refreshed and forgets all the fatigue of material activities simply by dipping into the transcendental ocean of Your pastimes. And eventually he merges into the ocean of transcendental bliss.
(Krsna Book).

People in general have a natural inclination to read narrations in which ordinary jīvas are glorified, but when they become attracted by the Vedic scriptures which delineate Your eternal pastimes, they actually dip into the ocean of transcendental bliss.
(Krsna Book).

The personified Vedas continued: “Dear Lord, it is very difficult to achieve perfect knowledge of the Absolute Truth. Your Lordship is so kind to the fallen souls that You appear in different incarnations and execute different activities. You appear even as a historical personality of this material world, and Your pastimes are very nicely described in the Vedic literature. Such pastimes are as attractive as the ocean of transcendental bliss.
(Krsna Book).

Vṛndāvana was always absorbed in the thought of Kṛṣṇa. Everyone remembered His pastimes and was constantly merged in the ocean of transcendental bliss. But the material world is so contaminated that even in Vṛndāvana the asuras, or demons, tried to disturb the peaceful situation.
(Krsna Book).
