In his purport to Srimad Bhagavatam 2.3.32 Srila Prabhupada writes, “Undoubtedly Bhagavad-gita was spoken by the Lord on the Battlefield of Kuruksetra just to encourage Arjuna to fight, and yet to complete the transcendental knowledge of Bhagavad-gita, the Lord instructed Uddhava. The Lord wanted Uddhava to fulfill His mission and disseminate knowledge which He had not spoken even in Bhagavad-gita.” Chapters 7-29 of the Srimad Bhagavatam’s 11th Canto are known as the “Uddhava Gita.”
