School of the Prophets (or something like that). A flavor of Sufis.

A dear friend was, if not a follower, at least quite friendly to sufism.

I found her points about it intriguing and worthy of contemplation. If I was going to join a cult then that might be the one to join ;-).

Of course there's a significant difference between a belief system and a group that practices that belief under a charismatic and dogmatic leader....
