Books that've helped you the most

[Zigzag Idiot]

It's more than just a book. It's an interpretive tool for divination that I consult just about on a daily basis. Modeled after the Original I CHING or Book of Changes which is considered the oldest book on earth.  

Many call it an updated version of the I-CHING in which the oppressive twist of patriarchical ideas have been removed.

From a review:

Removing the Ego as the defining agent of reality releases awareness to reinhabit the natural world. --Jose Cedillos, Ph.D. Prof. of Consciousness and Creativity Studies, The Union Institute.

Anything from Jed McKenna. But be advised, he's a straight-out no-bullshit in-your-face author.
