“A bona fide spiritual master is in the disciplic succession from time eternal, and he does not deviate at all from the instructions of the Supreme Lord as they were imparted millions of years ago to the sun-god, from whom the instructions of Bhagavad-gita have come down to the earthly kingdom. One should, therefore, follow the path of Bhagavad-gita as it is expressed in the Gita itself and beware of self-interested people after personal aggrandisement who deviate others from the actual path.”

Srila Prabhupada [B.G. 4.42]
