While Tantra has mystical, philosophical, and religious aspects it is, above all, a technique of action -- a system of physical, mental, and spiritual discipline incorporating meditation, yoga, and sacramental worship in the widest sense of the phrase. Tantra for Westerners is a complete theoretical and practical guide to the Way of Action, covering concepts of pleasure and pain, power and passivity, esoteric physiology, Tantra and Qabalism, right-hand and left-hand Tantra, tantric rituals for westerners, and the arousal of kundalini -- the serpent power.
