SB 1.1.3: O expert and thoughtful men, relish Śrīmad-Bhāgavatam, the mature fruit of the desire tree of Vedic literatures. It emanated from the lips of Śrī Śukadeva Gosvāmī. Therefore this fruit has become even more tasteful, although its nectarean juice was already relishable for all, including liberated souls.
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.
