The affection and the dealings of love that are different branches of the original tree of love precede many varieties of affectionate manifestations that will not be discussed here. These different manifestations have been described by Sanātana Gosvāmī in his Bhāgavatāmṛta. Although the subject of such affections and dealings of love is very confidential, Sanātana Gosvāmī has described them very explicitly.
Śrī Rūpa Gosvāmī thus concludes the first division of the Bhakti-rasāmṛta-sindhu, offering up his treatise for the transcendental pleasure of Sanātana Gosvāmī, who has established the transcendental beauty, and of Gopāla Bhaṭṭa Gosvāmī, Śrī Raghunātha Bhaṭṭa Gosvāmī and Raghunātha dāsa Gosvāmī. It appears from this statement that the great Śrīla Jīva Gosvāmī was not yet active when Bhakti-rasāmṛta-sindhu was written.

In this second division of Bhakti-rasāmṛta-sindhu the author offers his respectful obeisances unto "Sanātana." This Sanātana can be interpreted as either Śrī Kṛṣṇa Himself or as Sanātana Gosvāmī, the elder brother and spiritual master of Rūpa Gosvāmī. In the case where "Sanātana" is accepted to mean Śrī Kṛṣṇa, the obeisances are offered to Kṛṣṇa because He is naturally so beautiful and because He is the killer of the demon Agha. If it is interpreted to mean Sanātana Gosvāmī, then it is because he is so greatly favored by Rūpa Gosvāmī, being always served by him, and because he is the annihilator of all kinds of sinful activities. In this division of Bhakti-rasāmṛta-sindhu the author wants to describe the general symptoms of the transcendental mellow (loving mood) of discharging devotional service.
In this division of Bhakti-rasāmṛta-sindhu there are five general topics: (1) vibhāva—special symptoms or causes of ecstasy, (2) anubhāva—subsequent ecstasy, (3) sāttvika-bhāva—constitutional or existential ecstasy, (4) vyabhicārī-bhāva—aggressive ecstasy and (5) sthāyi-bhāva—fervent or continuous ecstasy.

The word rasa, used in the Bhakti-rasāmṛta-sindhu, is understood by different persons differently because the exact English equivalent is very difficult to find. But as we have seen our spiritual master translate this word rasa into "mellow," we shall follow in his footsteps and also translate the word in that way.

Śrīla Rūpa Gosvāmī gives us a vivid description of Kṛṣṇa as the reservoir of all pleasure in his Bhakti-rasāmṛta-sindhu. Here are some parts of that description.
Kṛṣṇa's kaiśora age may be divided into three parts. In the beginning of His kaiśora age—that is, at the beginning of His eleventh year—the luster of His body becomes so bright that it becomes an impetus for ecstatic love. Similarly, there are reddish borders around His eyes, and a growth of soft hairs on His body. In describing this early stage of His kaiśora age, Kundalatā, one of the residents of Vṛndāvana, said to her friend, "My dear friend, I have just seen an extraordinary beauty appearing in the person of Kṛṣṇa. His blackish bodily hue appears just like the indranīla jewel. There are reddish signs on His eyes, and small soft hairs are coming out on His body. The appearance of these symptoms has made Him extraordinarily beautiful."

When one transcends the status of ecstatic love and thus becomes situated on the highest platform of pure goodness, one is understood to have cleansed the heart of all material contamination. In that pure stage of life, one can taste this nectar, and this tasting capacity is technically called rasa, or transcendental mood.
Thus ends the Bhaktivedanta summary study of the second division of Bhakti-rasāmṛta-sindhu, in the matter of general devotional service.

Srila Rupa Goswami offers his respectful prayers to the eternal Supreme Personality of Godhead, who is always so beautiful and for whom the pure devotees are always engaged in loving transcendental service. This third division of Bhakti-rasāmṛta-sindhu describes the five primary kinds of devotional service—namely neutrality, servitude, fraternity, parenthood and conjugal love. These five items will be very elaborately explained here, and thus they have been figuratively described as the five waves on the western side of this ocean of the nectar of devotion.
When one is actually able to maintain the transcendental position, his stage is called neutrality in devotional service. Some great sages have attained this neutral position by practicing austerity, penance and meditation to control the senses. Such sages are generally called mystic yogīs, and in most cases they are inclined to appreciate the spiritual pleasure of the impersonal feature of the Absolute Truth. They are practically unaware of the transcendental pleasure derived from personal contact with the Supreme Godhead.

The qualifications of a saintly person are described in the Bhakti-rasāmṛta-sindhu as follows. A saintly person is one who understands fully that simply by discharging devotional service he can become confident of liberation. He is always situated in the regulative principles of devotional life and at the same time aspires to be liberated from material entanglement.

In the Bhakti-rasāmṛta-sindhu it is stated that all those who attended the pious meeting held by Lord Brahmā for the study of Vedic literature like the Upaniṣads became overwhelmed with ecstatic love for Kṛṣṇa, the chief of the Yadu dynasty. Actually, the result of studying the Upaniṣads is to understand the Supreme Personality of Godhead. Negation of material existence is only one of the subjects of the Upaniṣads. The next subject concerns becoming situated in the impersonal realization. And then, after penetrating through the impersonal Brahman, when one comes to the platform of associating with the Supreme Personality of Godhead, one reaches the ultimate goal in studying the Upaniṣads.

Regarding concentration of the eyesight on the tip of the nose, there is a statement in the Bhakti-rasāmṛta-sindhu by a devotee who observed this being performed by a yogī. He remarked, "This great sage is concentrating his eyesight on the tip of his nose, and from this it appears that he has already realized the eternal form of the Lord within himself."
(Nectar of Devotion).

In the Bhakti-rasāmṛta-sindhu it is said that when Lord Kṛṣṇa was blowing His conchshell known as Pāñcajanya, many great sages who were living in the caves of the mountains immediately reacted, being awakened from their trance of meditation. They immediately saw that the hairs of their bodies were standing. Sometimes devotees in śānta-rasa become stunned, peaceful, jubilant, deliberate, reflective, anxious, dexterous and argumentative. These symptoms indicate continuous ecstasy, or established emotion.

In the fourth division of Bhakti-rasāmṛta-sindhu, Śrīla Rūpa Gosvāmī has described seven kinds of indirect ecstasies of devotional service, known as laughing, astonishment, chivalry, compassion, anger, dread and ghastliness. In this portion, Śrīla Rūpa Gosvāmī further describes these ecstasies of devotional feelings, some being compatible and others incompatible with one another. When one kind of ecstatic devotional service overlaps with another in a conflicting way, this state of affairs is called rasābhāsa, or a perverted presentation of mellows.

One should accept this opportunity to return home, back to Godhead, very enthusiastically. Without enthusiasm, one cannot be successful. Even in the material world one has to be very enthusiastic in his particular field of activity in order to become successful. A student, businessman, artist or anyone else who wants success in his line must be enthusiastic. Similarly, one has to be very enthusiastic in devotional service. Enthusiasm means action, but action for whom? The answer is that one should always act for Kṛṣṇa—kṛṣṇārthākhila-ceṣṭā (Bhakti-rasāmṛta-sindhu).

Avyabhicāriṇī bhakti means unalloyed devotion. A person engaged in devotional service must be free from material motives. In this Kṛṣṇa consciousness movement, one's consciousness must be changed. If consciousness is aimed toward material enjoyment, it is material consciousness, and if it is aimed toward serving Kṛṣṇa, it is Kṛṣṇa consciousness. A surrendered soul serves Kṛṣṇa without material considerations (anyābhilāṣitā-śūnyam (Bhakti-rasāmṛta-sindhu 1.1.11)). Jñāna-karmādy-anāvṛtam: unalloyed devotional service, which is transcendental to the activities of the body and mind, such as jñāna (mental speculation) and karma (fruitive work), is called pure bhakti-yoga. Bhakti-yoga is the proper activity of the soul, and when one actually engages in unalloyed, uncontaminated devotional service, he is already liberated (sa guṇān samatītyaitān (B.G.14:26). Kṛṣṇa's devotee is not subjected to material condition, even though his bodily features may appear materially conditioned.

One krośa equals two square miles. When one makes Vṛndāvana his residence, he should take shelter of an advanced devotee there. In this way one should always think of Kṛṣṇa and His pastimes. This is further elucidated by Śrīla Rūpa Gosvāmī in his Bhakti-rasāmṛta-sindhu (1.2.294):
kṛṣṇaṁ smaran janaṁ cāsya
preṣṭhaṁ nija-samīhitam
tat-tat-kathā-rataś cāsau
kuryād vāsaṁ vraje sadā
"A devotee should always reside in the transcendental realm of Vraja and always engage in kṛṣṇaṁ smaran janaṁ cāsya preṣṭham, the remembrance of Śrī Kṛṣṇa and His beloved associates. By following in the footsteps of such associates and by entering under their eternal guidance, one can acquire an intense desire to serve the Supreme Personality of Godhead."

(Nectar of Instruction).

Again Śrīla Rūpa Gosvāmī states in Bhakti-rasāmṛta-sindhu (1.2.295):
sevā sādhaka-rūpeṇa
siddha-rūpeṇa cātra hi
tad-bhāva-lipsunā kāryā
vraja-lokānusārataḥ
"In the transcendental realm of Vraja (Vraja-dhāma) one should serve the Supreme Lord, Śrī Kṛṣṇa, with a feeling similar to that of His associates, and one should place himself under the direct guidance of a particular associate of Kṛṣṇa and should follow in his footsteps. This method is applicable both in the stage of sādhana (spiritual practices executed while in the stage of bondage) and in the stage of sādhya (God realization), when one is a siddha-puruṣa, or a spiritually perfect soul."
