First published in English in 1935, this volume of seven authentic Tibetan yoga texts serves as a companion to The Tibetan Book of the Dead. Illustrated with photographs and reproductions of yoga paintings and manuscripts, this edition contains some of the principal meditations used by illustrious Hindu and Tibetan gurus and philosophers through the ages in attaining Right Knowledge and Enlightenment. Special commentaries precede each carefully-rendered text, and a comprehensive preface contrasts the tenets of Buddhism with European concepts of religion, philosophy, and science.
