Before my presentation of Bhagavad-gita As It Is, almost all the English editions of Bhagavad-gita were introduced to fulfill someone?s personal ambition. . . . Generally the so-called scholars, politicians, philosophers, and svamis, without perfect knowledge of Krsna, try to banish or kill Krsna when writing commentary on Bhagavad-gita. Such unauthorized commentary upon Bhagavad-gita is known as Mayavada-bhasya, and Lord Caitanya has warned us about these unauthorized men.
