Just got the book through the post, and started reading straight away.
The sub title is, "The Way of the Secret Lover"
It's an old and small book written in 1990s, but feels so fresh new for some reason. It disects tarot cards logically, and talks about the significance of Holy Gourdian Angel. Sex magic and tantra seems bonus addendum in later part of the book, which makes the book even more interesting.
Highly recommended.
