Uddhava Gita consists of Krishna's final discourse to Uddhava before Krishna draws his worldly 'descent' to completion. Though the Uddhava Gita is often published singularly as a stand-alone work, it is also evident in the Eleventh Canto of the Bhagavata Purana commencing from verse 40 section 6 through to the end of section 29, comprising more than 1000 'verses' and is considered part of the Purana literature proper.
