"There are many different kinds of devotees, but even a Vaisnava coming from a family of mlecchas or yavanas is understood to be a learned scholar, complete in knowledge, if he knows the Vaisnava philosophy. He should therefore be given charity, for such a Vaisnava is as worshipable as the Supreme Personality of Godhead."
