Question: Must a spiritual master be a Vaisnava?
Does a spiritual master need to be a Vaisnava devotee? Some christians I know have what they call a spiritual director. Is this a righteous equivalent of a guru? Thank you once again for your kind service to the Creator's creation.
Answer: How can he not be a Vaisnava?
"Vaisnava" is not a sectarian designation. It means someone who is devoted to the Supreme Person in any one of His multifarious forms. So any bona fide spiritual director or guru must necessarily be a Vaisnava. If someone is not devoted to the Supreme Person how can they be fit to be a bona fide guru or spiritual director? It is not possible.
