“A deck of Tarot cards is a magick temple (indeed, an entire universe) in a box. Each card represents a particular facet of the magickal universe around us and within us. The deck is the ultimate pantacle - organized upon the purest of qabalistic principles. There is no aspect of consciousness that cannot be located on or represented by one or more Tarot cards. Even ‘nothingness’ can be found in the formless inscrutability of the Tarot.
