I've thought a few things.
(1) The Cabbalists cum numerologists have spent centuries praying and rearranging the order of the letters in the Torah ~ in search of the correct, the ultimate name of God! The I Ching is a comprehensive book of wisdom, which you approach by reading passages (somewhat) randomly. The Tarot is a similar fixed set of symbols which you rearrange and ask a question of. These are all holy books, the Book of Life in its many manifestations. The search is not for truth in an ontical sense ~ nor in a universal objective sense (for, of course, these views are incorrect). Rather, it is for the world of the reading individual. Only Dasein can read the Truth. And, the set of symbols which forms that Truth for Dasein A is likely to not be the same set of symbols in the Truth of Dasein B. Okay, this is obvious, but only because I'm articulating it.
(2) Nihilism. My letter to Mango about nihilism miscarried its message. But I know why. He looks at the world ontically. The nihilist is not transformed from Lion to Horus when he decided what he wants. It is when he realizes his (to paraphrase Crowley paraphrasing Nietzsche) one true Will. The Great Work begins then. It is the realization of the failure of its burden to explain / solve existence which transforms Camel into Lion. It can only be learning the "secret of the universe," the One True Will, attaining the "knowledge and conversation of the Holy Guardian Angel" which transforms the Lion into the Child. Om Mani Padme Hum.
