“Bhagavad-gita is the narration or the philosophy or the science of God, spoken by Krishna Himself. Shrimad-Bhagavatam is the narration about the activities and transcendental pastimes of Krishna. Both are Krishna-katha. It is the order of Lord Chaitanya that Krishna-katha should be spread all over the world, because if the conditioned souls, suffering under the pangs of material existence, take to Krishna-katha, then their path of liberation will be open and clear.” (Shrila Prabhupada, Krishna, The Supreme Personality of Godhead, Vol 1, Introduction)
