I am still working on one of the very first exercises (which seems to be one of the hardest ones), and am not a heavy practioner of the occult, but from my intuitions and experiences with the book so far, it definitely seems to hold an endless store of wisdom. I really wish I had had the opportunity to meet the author so I could see what he was really like. If he was like all those who talk like they know so much, but have nothing to show for all their "knowledge", or if he was truly accomplished. I half expect I might have been quite surprised if I'd actually had a chance to meet the guy and get to know him. This isn't your typical occult book full of endless exposition, rambling, and psychological points of view. It is very direct and to the point. I haven't yet even breached the surface with this book (which seems a very difficult thing to do indeed), and already the very first simple exercises have accomplished wonders for me. The one where you impregnate your food with your wishes accomplished something I was unable to accomplish for years and the shower thing where you use a brush to open your pores every day in the shower and take cold ones also seemed to somehow open up my senses. The time that I stuck to that every day was a very weird time with all kinds of syncronycities and supernatural seeming things happening to me... Unfortunately, the things this book asks of one are not the easiest things to stick to (or even do at all) in the world, but I would recommend it as one of the rare books on the occult that actually seems to have some real substance, and if it draws you, you should buy it. I almost don't want to tell you this; almost want to hoard this secret wisdom for myself...
