The famous magician and mystic Aleister Crowley speaks in simple and understandable language about these ancient spiritual, mental and physical practices, which not only give the power and energy necessary for magical operations, but also lead to connection with the Divine world. There is more nonsense told or written about yoga than anything else in the world. Most of this nonsense, which is encouraged by charlatans, is based on the idea that there is something mystical or oriental about it. Does not exist. Do not look in me for odalisks or obelisks, rahat-lukums or any other images of the ostentatious brilliance of his merchants . I'm talking about it, not about it......................................... There is nothing mystical or oriental about anything, as anyone who has spent a reasonable amount of time on the continents of Asia and Africa knows. But now I'm going to shed a pure light on this subject - the light of common sense. This is not a book to be read while standing or on the run. This is a masterpiece of high trial, combining all the achievements of a person who has experienced in practice and mastered almost all known methods of spiritual development. This book, full of humor, wisdom and useful advice, is an indispensable guide for every student who considers yoga his "path".
