bhagavatam

"This Bhagavata Purana is as brillant as the sun, and it has arisen just after the
departure of Lord Krishna to His own abode, accompanied by religion, knowledge, etc.
Persons who have lost their vision due to the dense darkness of ignorance in the age of Kali shall get light from this Purana." (Srimad-Bhagavatam 1.3.43)

The timeless wisdon of India is expressed in the Vedas, ancient Sanskrit texts that touch upon all fields of human knowledge. Originally preserved through oral tradition, the Vedas were first put into writing 5,000 years ago by Srila Vyasadeva, the "literary incarnation of God." After compiling the Vedas, Vyasadeva set forth their essence in the aphorisms know as Vedanta-sutras. Srimad-Bhagavatam (Bhagavata Purana) is Vyasadeva's commentary on his own Vedanta-sutras. Referred to as "the ripened fruit of the tree of Vedic literature," Srimad-Bhagavatam is the most complete and authoritative exposition of Vedic knowledge.
