Srimad Bhagavatam

The Bhagavata Purana is considered to be the purest and greatest of all the puranas since it invokes devotion towards Lord Vishnu and his various incarnations, primarily focusing on Krishna since he was the complete incarnation of Lord Vishnu. The Bhagavata Purana truly reveals the means for becoming free from all material work, together with the processes of pure transcendental knowledge, renunciation and devotion to Lord Vishnu and anyone who seriously tries to understand, hears and chants the verses of the Bhagavata Purana with devotion to Lord Vishnu, becomes completely liberated from material bondage and attains moksha or liberation from the cycle of births and deaths in the material world.
