Luminous Emptiness: Understanding the Tibetan Book of the Dead, by Francesca Fremantle.
From my capsule review in a Vacation Reading roundup:
- Excellent book! The first section of the book discusses the philsophical, spiritual, historical and sometimes philological background; the second half's a commentary on "Liberation through Hearing", whose first English translation was given the title "Tibetan Book of the Dead" in a (successful) attempt to leverage the marketing buzz of the Egyptian Book of the Dead. Very clearly and beautifully written.
