Every living entity, beginning from Brahmā, the first-born living being within the material world, down to the insignificant ant, desires to relish some sort of taste derived from sense perceptions. These sensual pleasures are technically called rasas. Such rasas are of different varieties. In the revealed scriptures the following twelve varieties of rasas are enumerated: (1) raudra (anger), (2) adbhuta (wonder), (3) śṛṅgāra (conjugal love), (4) hāsya (comedy), (5) vīra (chivalry), (6) dayā (mercy), (7) dāsya (servitorship), (8) sakhya (fraternity), (9) bhayānaka (horror), (10) bībhatsa (shock), (11) śānta (neutrality), (12) vātsalya (parenthood).
The sum total of all these rasas is called affection or love. Primarily, such signs of love are manifested in adoration, service, friendship, paternal affection, and conjugal love. And when these five are absent, love is present indirectly in anger, wonder, comedy, chivalry, fear, shock and so on. For example, when a man is in love with a woman, the rasa is called conjugal love. But when such love affairs are disturbed there may be wonder, anger, shock, or even horror. Sometimes love affairs between two persons culminate in ghastly murder scenes. Such rasas are displayed between man and man and between animal and animal. There is no possibility of an exchange or rasa between a man and an animal or between a man and any other species of living beings within the material world. The rasas are exchanged between members of the same species. But as far as the spirit souls are concerned, they are one qualitatively with the Supreme Lord. Therefore, the rasas were originally exchanged between the spiritual living being and the spiritual whole, the Supreme Personality of Godhead. The spiritual exchange or rasa is fully exhibited in spiritual existence between living beings and the Supreme Lord.
The Supreme Personality of Godhead is therefore described in the śruti-mantras, Vedic hymns, as "the fountainhead of all rasas." When one associates with the Supreme Lord and exchanges one's constitutional rasa with the Lord, then the living being is actually happy.
These śruti-mantras indicate that every living being has its constitutional position, which is endowed with a particular type of rasa to be exchanged with the Personality of Godhead. In the liberated condition only, this primary rasa is experienced in full. In the material existence, the rasa is experienced in the perverted form, which is temporary. And thus the rasas of the material world are exhibited in the material form of raudra (anger) and so on.
Therefore, one who attains full knowledge of these different rasas, which are the basic principles of activities, can understand the false representations of the original rasas which are reflected in the material world. The learned scholar seeks to relish the real rasa in the spiritual form. In the beginning he desires to become one with the Supreme. Thus, less intelligent transcendentalists cannot go beyond this conception of becoming one with the spirit whole, without knowing of the different rasas.
In this śloka, it is definitely stated that spiritual rasa, which is relished even in the liberated stage, can be experienced in the literature of the Śrīmad-Bhāgavatam due to its being the ripened fruit of all Vedic knowledge. By submissively hearing this transcendental literature, one can attain the full pleasure of his heart's desire. But one must be very careful to hear the message from the right source. Śrīmad-Bhāgavatam is exactly received from the right source. It was brought by Nārada Muni from the spiritual world and given to his disciple Śrī Vyāsadeva. The latter in turn delivered the message to his son Śrīla Śukadeva Gosvāmī, and Śrīla Śukadeva Gosvāmī delivered the message to Mahārāja Parīkṣit just seven days before the King's death. Śrīla Śukadeva Gosvāmī was a liberated soul from his very birth. He was liberated even in the womb of his mother, and he did not undergo any sort of spiritual training after his birth. At birth no one is qualified, neither in the mundane nor in the spiritual sense. But Śrī Śukadeva Gosvāmī, due to his being a perfectly liberated soul, did not have to undergo an evolutionary process for spiritual realization. Yet despite his being a completely liberated person situated in the transcendental position above the three material modes, he was attracted to this transcendental rasa of the Supreme Personality of Godhead, who is adored by liberated souls who sing Vedic hymns. The Supreme Lord's pastimes are more attractive to liberated souls than to mundane people. He is of necessity not impersonal because it is only possible to carry on transcendental rasa with a person.
