As Chogyam Trungpa writes in his foreword: "It is in the flow of karma that this book materialized in 1959 on the very eve of the destruction of the spiritual land of Tibet. Professor Guenther was instrumental in making available the only commentary and guide in English to the bodhisattva tradition of Tibet, Japan, and China. The book remains the classic text of all Buddhists."
