His official web site has a photo section, 7 different close ups, all available for purchase, certainly looks to me that they are intended for devotion/reverence/meditation.
He does have official disciples, that term "disciple" used, Katie Davis is one.
His story is included in the book Mystics, Masters, Saints, and Sages: Stories of Enlightenment by Robert Ullman and Judyth Reiche
