The deepest esoteric mystery involves taking one headless Osiris and replacing it with the head of one's own choice, the Sethian Ass, the magic involved will lead to others seeing one as Osiris incarnate, bringer of love, peace and light, whereas one is simply a Sethian Ass.
This ritual is first credited to Moses and all teachers subsequently within Abrahamic tradition have been complete Asses albeit with much pretentiousness.
