(i. e . Song of Krishna), a poem introduced into the Mahâbhârata, divided into three sections, and each section into six chapters, called Upanishads; being a series of mystical lectures addressed by Krishna to his royal pupil Arjuna on the eve of a battle, from which he shrunk, as it was with his own kindred; the whole conceived from the point of view or belief, calculated to allay the scruples of Arjuna, which regards the extinction of existence as absorption in the Deity.
