Origionally from Bulgaria, a student of the well respected Peter Dunov, he founded the "White Brotherhood" and taught Western mysticism, based on esoteric Christianity, in Europe from 1960(?) until his death in the mid-1980s. The Indian sage Nityananada said on meeting him, "A pure heart, peace in his soul, and all power has been given to him."
Aivanhov speaks:
Purification. "Our nature must become purified so that the divine light which is inside all, can shine through."
