"The Qabalah is a system of relationships among mystical symbols which can be used, as was said by Paracelsus, to open up access to the hidden reaches of the mind—beyond the frontiers of reason. The Qabalah gives the means to penetrate behind symbolism. It is the mystical process in reverse. The Tree of Life is a comprehensive symbol encompassing other symbol systems, religious beliefs, mythologies, and provides a means of interpreting them based on abstract and universal principles.”
Some people spend half their lives in the pentagram (...you know who you are). Me, i'm happiest when i'm outside the pentagram... well and truly outside. Despite my lack of interest in all things pentagram and its ilk, I do know a number of people who are involved in the esoteric metaphysical arts. I was even once asked if I was interested in joining a small group of believers. I politely declined explaining that as an atheist it's wasn't something I could reasonably be involved with, particularly since most of my time was being spent looking out for the Invisible Pink Unicorn.
Books on the occult or any other forms of mysticism associated with the Hermetic Order of the Golden Dawn, are something that I rarely find any of. I did find a copy of Ordines Descendens a while ago and still have it sitting on the shelf waiting for someone to step out of the pentagram long enough to place an order. Unfortunately this hasn't happened as of yet and i'm hoping for a wrong alignment of the stars in the near future. When this happens, i'm sure there will be a smell of sulpher in my paypal account (?).
