Bardo Thodol or the Tibetan book of the Dead can sometimes be mistaken as a dire and gruesome text. But nothing could be further from the truth.
Bardo Thodol teaches you about the nature of dying so you can understand the nature of life. The book acts as a guide for the dead during the state that intervenes death and the next rebirth. I highly recommend everyone who seeks a higher understanding of life to read it.
