First published in 1927, The Tibetan Book of the Dead, or the Bardo Thodol, has since been revised and repreinted in several editions; for the Galaxy Books edition, Dr. Evans-Wentz has prepared a special Preface. Although the Bardo Thodol is used in Tibet as a breviary, and read or recited on the occasion of death, it was originally conceived to serve as guide not only for the dying and the dead, but for the living as well. As a contribution to the science of death and of existence after death, and of rebirth, The Tibetan Book of the Dead is unique among the sacred books of the world.
