According to Srila Sridhara Svami, the Supreme Lord has briefly described to Uddhava the essential wisdom of all the Upanishads, with the conclusion that pure devotional service to the Lord is the real means of ultimate liberation. In this regard Srila Bhaktisiddhanta Sarasvati Thakura emphasizes that although hatha-yogis and raja-yogis try to make progress along their prescribed paths, they confront obstacles and often fail to achieve their desired goals. However, one who surrenders to the Supreme Lord will certainly be victorious on his spiritual path back home, back to Godhead.
Thus end the purports of the humble servants of His Divine Grace A. C. Bhaktivedanta Swami Prabhupada to the Eleventh Canto, Twenty-eighth Chapter, of the Srimad-Bhagavatam, entitled "Jnana-yoga."
