i'm almost finished the very brilliant illuminating and enjoyable book called 'the magical universe of william burroughs' which i've devoured with a lot of pleasure. 
if you feel inclined to hack yourself, and then make several excursions into hacking  this reality thang, this is a great primer and a good place to start. of course the concepts and ideas are much more sophisticated these days, but in these pages one is presented with an organic version of what most magickians would know and use.
