The Gita is an evolving response which deals with the conflicts between Veda and Vedanta and then with the challenge posed to Vedanta by Buddhism. Its shift to Bhakti is the climax of the battle between Brahmanism and Buddhism. There are probably multiple authors of the Gita as shown by stylistic changes and the frequent shift of subject matter. For Meghnad Desai, Gita is a secular text, a result of human creation over several centuries. He also contends that some themes in the Gita reinforce social inequality and lack of concern for the other and to that extent he finds Gita to be toxic.
