SB 1.1 - The mature fruit of the desire tree
Śrīmad Bhāgavatam is 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 (rasam ālayam) was already relishable for all, including liberated souls. Thus the Bhāgavatam is not only a superior literature, being transcendental to all mundane activities and knowledge, but it is the ripened fruit of all Vedic literatures. With great respect and attention, one should receive the message and lessons imparted by Śrīmad Bhāgavatam. Having described the powers of Bhāgavatam to capture the Lord in the heart, this verse describes the sweetness of Bhāgavatam.
The Vedas are compared to the desire tree because they contain all things knowable by man. They deal with mundane necessities as well as spiritual realization. They deal with regulated principles of knowledge covering social, political, religious, economic, military, medicinal and all that is necessary to keep body and soul together. The Vedas give fruit in the form of the four puruṣārthas, which are desired by those who resort to it. However, the fulfillment of material desires is not the ultimate purpose of the Vedas. Rather, the Vedas gradually encourages spiritual advancement, and thus they are divided into sections, each of which emphasizes appropriate practices for individuals at different levels of advancement. The eighteen Purāṇas, for example, are divided into three divisions for people influenced by each of the three modes of nature. One Purāṇa may therefore appear to contradict another in its instructions and emphasis. Even after compiling all Vedic literature, Vyāsa was dissatisfied till he compiled the Bhāgavatam. The Veda also gives the fruit known as Bhāgavatam because some people desire that.
