The Bhagavata Purana, literally meaning Divine-Eternal Tales of The Supreme Lord, is considered the most important of the Puranas. The Puranas are believed to be compiled by Vyasa, the narrator and Bhagavad Gita, whose birth is dated at 3.374 BC. The Puranas, along with the Vedas and Itihaasas form the massive religious bedrock of the intellectual Hindu tradition.
These literary works of high quality go back in time to perhaps more than five millennia. In The Bhagavata Purana, complex religious and spiritual concepts like Advaita, Yoga, Bhakti, and Dharma are introduced for the first time.
