First off, nowhere does it state that this book is about the Tantra. This book is German Occult Sex Magic at its finest and most practical. It is about magic, about using your sexual energy, releasing it, and bringing about changes.
I grew up reading the likes of Cavendish, Waite, and others, and, personally, I like this book. It's breathing exercises are fantastic, it's sigil magic is great. It's inspiring and never sets on my bookshelf for very long.
I bought this since practical sigil magic was hard to find.
It has the extra specifics & extracurricular activities tied to german sex magic in kind of a handy guide.
I've used the techniques to gain results in doing magic and improving my life.
To those who see it as vile or "black, etc etc"....no duh. This ain't for you. This is not even for people interested in tantra. Sure, it glosses over the tantra subject, but tantra is only a means to an end here. Were here to do MAGIC. Look at your life and see just what kind of MAGIC you've created. Tough to accept, I know.
Anyways, it's a 4 star read since it worked for me. But most of the book's subject matter is extracurricular to the basic sex magic techniques available in practical sigil magic(or on the internet). I just wanted something in my possession.
