Such unauthorized commentary upon Bhagavad-gītā is known as Māyāvāda-bhāṣya, and Lord Caitanya has warned us about these unauthorized men. Lord Caitanya clearly says that anyone who tries to understand Bhagavad-gītā from the Māyāvādī point of view will commit a great blunder. The result of such a blunder will be that the misguided student of Bhagavad-gītā will certainly be bewildered on the path of spiritual guidance and will not be able to go back to home, back to Godhead.
