"This book is an extremely lucid overview of the generation and completion stages of Highest Yoga Tantra." —The Middle Way

"This book deserves to be a most popular book on Tantra. It captures both the essence and detail that bring these esoteric topics to life." —Jeffrey Hopkins, University of Virginia

"The best introduction to the subject, well-written and authoritative." —John Powers, Australian National University

"Although the Kalachakra Tantra contains unique qualities not found elsewhere in Indo-Tibetan Buddhism, it is essential to understand that it also exemplifies the category of practices referred to as Anuttara Yoga tantra (highest yoga tantra). Cozort's now-classic text is peerless as an introduction to the theoretical and practical underpinnings of highest yoga tantra and to the relationship of this level of practice to sutra traditions and the Buddhist path as a whole. A special section comparing the completion stage in the Kalachakra to that of Guhyasamaja will be especially informative and helpful for the aspiring student and practitioner." —Mandala: A Tibetan Buddhist Journal

"Professor of religion Daniel Cozort offers the fruits of his studies with numerous Tibetan lamas. . . . Highly recommended for anyone interested in learning more about or personally experiencing the highest tantras." —Wisconsin Bookwatch
