Mayavadis are demons

Krsna states in the Bhagavad-gita (15.15), vedais ca sarvair aham eva
vedyah. When Krsna says aham, He says “I am,” which means “I,” the person.
He adds the word eva, which is used for conclusive verification. Thus by
studying Vedanta philosophy one must come to know the Supreme Person.
Whoever describes Vedic knowledge as impersonal is a demon.
