The external features exhibited on the bodies of devotees are called udbhāsvara. The vyabhicārī symptoms are thirty-three in number, and they primarily involve words uttered by the devotee and various bodily features. Different bodily features—such as dancing, trembling and laughing—sometimes mix with the vyabhicārī symptoms, which are also called sañcārī. When bhāva, anubhāva and vyabhicārī symptoms are combined, they make the devotee dive into the ocean of immortality. That ocean is called thebhakti-rasāmṛta-sindhu, the ocean of the pure nectar of devotional service, and one who is merged in that ocean is always rapt in transcendental pleasure on the waves and sounds of that ocean.
(Teachings of Lord Caitanya).

The supreme lover is Kṛṣṇa in Vṛndāvana, and the supreme beloved is Rādhārāṇī. Kṛṣṇa has sixty-four main qualities, and His devotee takes transcendental pleasure in hearing of them. As explained in the Bhakti-rasāmṛta-sindhu, the characteristics are as follows: (1) His body is well constructed; (2) His body is full of auspicious symptoms; (3) His body is beautiful; (4) He is very glorious; (5) He is very strong; (6) He always looks like a boy of sixteen; (7) He is well versed in various languages; (8) He is truthful; (9) He is decorated with pleasing words; (10) He is expert in speaking; (11) He is very learned; (12) He is very intelligent; (13) He is influential; (14) He is joyful; (15) He is cunning; (16) He is expert; (17) He is grateful; (18) He is firmly convinced; (19) He knows how to deal with different circumstances; (20) He is always conversant with scriptural injunctions; (21) He is clean; (22) He is controlled by His devotees; (23) He is steady; (24) He is self-controlled; (25) He is forgiving; (26) He is grave; (27) He is self-satisfied; (28) He is fair in His dealings; (29) He is magnanimous; (30) He is religious; (31) He is a great hero; (32) He is merciful; (33) He is respectful; (34) He is competent; (35) He is gentle; (36) He is modest; (37) He is the protector of the souls surrendered unto Him; (38) He is the deliverer; (39) He is the friend of the devotees; (40) He is submissive to love; (41) He is all-auspicious; (42) He is most powerful; (43) He is famous; (44) He is devoted to all living entities; (45) He is worshipable by everyone; (46) He is very attractive to all women; (47) He is partial to His devotees; (48) He is full of all opulence; (49) He is the supreme controller; (50) He possesses all honor.
(Teachings of Lord Caitanya).

Thus Kṛṣṇa and Rādhārāṇī are both transcendentally qualified, and They attract one another. But Rādhārāṇīs transcendental attractiveness is greater than Kṛṣṇa's, for Her attractiveness is the transcendental taste in conjugal love. Similarly, there are transcendental tastes in servitorship, friendship and other relationships with Kṛṣṇa. These can be described with reference to the context of the Bhakti-rasāmṛta-sindhu.
(Teachings of Lord Caitanya).

Persons who have been thoroughly cleansed by devotional service and are always joyful, being situated in elevated consciousness, who are very much attached to studying Śrīmad-Bhāgavatam, who are always cheerful in the association of devotees, who have accepted the lotus feet of Kṛṣṇa as the ultimate shelter of their lives, and who are pleased to perform all details of devotional service—such devotees have in their pure hearts the transcendental ecstasy of attachment, which has been developed through old and new reformatory practices. That ecstatic state of being, enriched with love of Kṛṣṇa and transcendental experience, gradually develops into the mature bliss of spiritual life. Tasting such spiritual bliss is not possible for those who are not situated in Kṛṣṇa consciousness and devotional service. This fact is further corroborated in the Bhakti-rasāmṛta-sindhu (2.5.131), where it is said: "It is very difficult for the nondevotee to understand the taste of devotional service. Only one who has completely taken shelter of the lotus feet of Kṛṣṇa and whose life is merged in the ocean of devotional service can understand this transcendental pleasure."
(Teachings of Lord Caitanya).

In other words, self-realization with a sense of servitude for the Lord is certainly transcendental, but when a sense of fraternity is added the relationship develops, and as affection increases, this relationship develops into parenthood and conjugal love. Rāmānanda Rāya then quoted a verse from the Bhakti-rasāmṛta-sindhu (2.5.38) stating that spiritual affection for the Supreme Lord is transcendental in all cases, but that the individual devotee has a specific aptitude for a particular relationship, and that relationship is more relishable for him than the others.
Such transcendental relationships with the Supreme Lord cannot be manufactured by the mental concoctions of pseudo-devotees. In this connection, Rūpa Gosvāmī has stated in his Bhakti-rasāmṛta-sindhu (1.2.101) that devotional service which makes no reference to the Vedic scriptures and which does not follow the principles set forth therein can never be approved. Śrīla Bhaktisiddhānta Sarasvatī Gosvāmī Mahārāja has also remarked that professional spiritual masters, professional Bhāgavatam reciters, professional kīrtana performers and those engaged in devotional service according to their own mental concoctions cannot be accepted.

(Teachings of Lord Caitanya).

The different kinds of devotees of the Supreme Lord have different aptitudes and relationships with Him. Any relationship with the Lord is as good as any other because the central point is Kṛṣṇa. In this connection there is a nice verse in the Bhakti-rasāmṛta-sindhu that states: "Kṛṣṇa is the reservoir of all pleasures, and He is always attracting the gopīs by the spiritual luster of His body. He especially attracts Tārakā, Pāli, Śyāmā and Lalitā. Kṛṣṇa is very dear to Rādhārāṇī, the foremost gopī." Like Kṛṣṇa, the gopīs are glorified by Kṛṣṇa's pastimes. There are different kinds of relationships with Kṛṣṇa, and anyone who is attracted to Kṛṣṇa in a particular mellow is glorified.

(Teachings of Lord Caitanya).

After hearing Rāmānanda Rāya speak of the qualities of Śrīmatī Rādhārāṇī and Kṛṣṇa, Lord Caitanya desired to hear from him about the reciprocal exchange of love between Them. Rāmānanda Rāya described Kṛṣṇa as dhīra-lalita, a word indicating a person who is very cunning and youthful, who is always expert in joking, who is without anxiety, and who is always subservient to his girlfriend. Kṛṣṇa is always engaged in loving affairs with Rādhārāṇī, and He takes to the bushes of Vṛndāvana to enjoy His lusty activities with Her. Thus He successfully carries out His lusty instincts. In the Bhakti-rasāmṛta-sindhu it is stated: “By His impudent and daring talks about sex indulgence, Kṛṣṇa obliged Śrīmatī Rādhārāṇī to close Her eyes, and taking advantage of this, Kṛṣṇa painted many pictures on Her breasts. These pictures served as subject matter for Rādhārāṇī’s friends to joke about. Kṛṣṇa was always engaged in such lusty activities, and thus He made His youthful life successful.”

(Teachings of Lord Caitanya).

In this connection, Śrīla Rūpa Gosvāmī states in his Bhakti-rasāmṛta-sindhu that the person whose only desire is to serve the Supreme Personality of Godhead may be situated in any condition in the material world, but he is to be understood as jīvan-mukta; that is to say, he is to be considered liberated while living within the body or the material world. The conclusion, therefore, is that a person fully engaged in Kṛṣṇa consciousness is a liberated person. Such a person actually has nothing to do with his material body or the material world. Those who are not in Kṛṣṇa consciousness are called karmīs and jñānīs, and they hover on the bodily and mental platforms and thus are not liberated. This situation is called kaivalya-nirasta-yoni. But a person situated on the transcendental platform is freed from the repetition of birth and death. This is confirmed in the Bhagavad-gītā, Fourth Chapter: "Simply by knowing the transcendental nature of the Supreme Personality of Godhead, Kṛṣṇa, one becomes free from the chains of the repetition of birth and death, and after quitting his present body he goes back home, back to Godhead." This is the conclusion of all the Vedas. Thus after understanding the prayers offered by the personified Vedas, one should surrender unto the lotus feet of Lord Kṛṣṇa.
(Krsna Book).

There is no material means of counteracting these sinful reactions. Administering a pain-killer provides temporary relief but cannot remove the root cause of a disease. Similarly, no materialistic effort aimed at counteracting sinful reactions can provide ultimate relief. One obtains maximum only by surrendering to the Supreme Lord. TheBhakti-rasāmṛta-sindhu (The Nectar of Devotion) supplies us with numerous proofs of how devotional service to the Lord destroys sinful reactions, and ignorance, the root of all sin. Hence we see that pious men depend solely on the Supreme Lord in moments of distress.

(Renunciation through Wisdom).

They fail to comprehend that the Supreme Lord is known as Hṛsīkeśa, "the supreme master of the senses." Sometimes a jñānī (a seeker of knowledge) or a practitioner of mystic yoga will also worship the Lord, but they also are merely interested ultimately in sensual pleasures. The only way these adulterated devotees can become pure devotees is if they read Śrīla Rūpa Gosvāmī's Bhakti-rasāmṛta-sindhu. This book is an authority on the science of devotional service.

(Renunciation through Wisdom).

The first word in devotional service is surrender. The only meaning of surrender is to accept that one is a servant of God. Even great scholars and philosophers like Dr. Radhakrishnan will have to perform heaps of austerities and penances before they will yield to the process of surrender. This is the conclusion of Bhagavad-gītā. Dr. Radhakrishnan's explanation of the six limbs of surrender is superficial. Originally defined in a Vaiṣṇava text, these six limbs of surrender pertain to Lord Viṣṇu, or Kṛṣṇa. Ānukūlya means "loving devotion to Lord Kṛṣṇa." The Bhakti-rasāmṛta-sindhu states, ānukūlyena-kṛṣṇānuśīlanaṁ bhaktir uttamā: (CC.2:19:167) "One should render transcendental loving service to Lord Kṛṣṇa favorably. That is called pure devotional service."

(Renunciation through Wisdom).

There is a wide gulf between superficial dabbling in philosophy to impress people with a few stock phrases, and a sincere search for knowledge of the Absolute. Through the speculative process it is impossible to fathom the inconceivable topics concerning the Absolute Truth, for they can be understood only through the science of devotion. As Śrīla Rūpa Gosvāmī writes in his Bhakti-rasāmṛta-sindhu, quoting from the Mahābhārata:
acintyāḥ khalu ye bhāvā
na tāṁs tarkeṇa yojayet
prakṛtibhyaḥ paraṁ yac ca
tad acintyasya lakṣaṇam
Anything transcendental to material nature is inconceivable and thus cannot be grasped through mundane arguments. Therefore one should not try to understand transcendental subjects in this way.

(Renunciation through Wisdom).

The guaranteed path to the aim of vidyā is described by Śrīla Rūpa Gosvāmī in his Bhakti-rasāmṛta-sindhu, which we have presented in English as The Nectar of Devotion. The culture of vidyā is summarized in Śrīmad-Bhāgavatam (1.2.14) in the following words:
tasmād ekena manasā
bhagavān sātvatāṁ patiḥ
śrotavyaḥ kīrtitavyaś ca
dhyeyaḥ pūjyaś ca nityadā
"Therefore, with one-pointed attention one should constantly hear about, glorify, remember and worship the Personality of Godhead, who is the protector of the devotees."

(Sri Isopanishad).
