Sorcerer Richard Eldritch's Number One Book Recommendation

The sorcerer supreme of the internet, the glorious Richard Eldritch, resident wizard on the lunatic outpost conspircay board and my friend and colleague, and I were chatting a couple of weeks about the best books on sorcery as Richard likes to call it.  We both picked the same Castenada book as of vital importance to understanding how the universe works, Journey to Ixtlan.  Read it.  It will do you good.
