I spent many hours reviewing as well as studying this book. Its content is extensive and illuminating. The problem with authoritative and even ancient sources is that these "road maps" to Power are best understood for those who have already traveled "these roads". The map is helpful but far from sufficient. The author does a fine job of giving the reader tools as well as a complete overview of the roots of this important and real discipline. The only criticism I have is that the philosophy extolled at the beginning and end of the book fails to drive home one important point, that is, that mind and body are of the same essence. Also, the explanation of the philosophical impetus and practical results lack clarity, noting that it is not always possible to make what is alogical lucid to limited human capacity. To complicate what is in essence simple, the words on the written pages of the sources are not what is always meant, for these words are simply there to "shine light on meaning". Therefore, relax and take your time reading this wonderful book. In any case this book is highly recommended for all serious students of yoga, meditation and the martial arts as well.
Layayoga is one of the four great systems of yoga, the other three being mantrayoga, hathayoga, and rajayoga, which together comprise the four forms of mahayoga. At the heart of Tantra is Kundaliniyoga, and at the core of Kundaliniyoga is Layayoga. Among its central tenets is the notion that the body is not, as taught by more ascetical schools, an obstacle on the path to enlightenment. Rather, it is a manifestation of the ultimate Reality and hence must be fully integrated into one's spiritual aspirations.
This work focuses on the esoteric process by which the ordinary human body is transmuted into a divine body, wherein every cell is suffused with consciousness and endowed with extraordinary capacities. "Laya" in fact refers to the absorption of the elements constituting the body, a process which occurs when the kundalini power rises from the chakra at the base of the spine and ascends toward the chakra at the crown of the head.
Drawing from over 280 Sanskrit texts, the author has achieved a comprehensive and academically rigorous presentation based on actual yogic experimentation and realization, which as such can help to address misconceptions common in Westernized presentations on Kundaliniyoga.
