Bardo Thodol
The Liberation Through Hearing During The Intermediate State (Standard Tibetan: bardo "liminality"; thodol as "liberation"), sometimes translated as Liberation Through Hearing or transliterated as Bardo Thodol, is a funerary text. It is often referred to in the West by the more casual title, Tibetan Book of the Dead, a name which draws a parallel with the ancient Egyptian Book of the Dead, another funerary text.
The Tibetan text describes, and is intended to guide one through, the experiences that the consciousness has after death, during the interval between death and the next rebirth. This interval is known in Tibetan as the bardo. The text also includes chapters on the signs of death, and rituals to undertake when death is closing in, or has taken place. It is the most internationally famous and widespread work of Tibetan Nyingma literature.
