Kundalini's power lies dormant in humans until it is awakened. The awakened Kundalini expresses the primal divine impulse and ultimately joins the individual with the divine. The development of the book parallels the development of the Kundalini within. Part One exposes the awakening and unfolding of the Kundalini; Part Two describes the piercing of the energy centers and the stages of ascent through the body; and Part Three examines Kundalini's relation to sexual expression.

The book provides a deep understanding of Tantra and of the underlying purpose of Tantracism. The author carefully considers the Caryakrama practices of sexual expression as a means of awakening and controlling Kundalini.

Silburn draws together passages from the Trika, Krama, and Kaula systems ranging through Abhinavagupta and Lalla and provides both translation and commentary for them. Chapters on the Chakras, the Nadis, and on mantras further elucidate the topic and lead to a forceful conclusion: Kundalini is the source of ultimate human knowledge and power.
