Bardo Thodol
The effect of a life review is often a strongly transformative experience. Experiencers describe them as extremely unpleasant from the perspective of the unhappiness they had inflicted on others, including feelings they had never dreamed of as resulting, and equally pleasant from the perspective of the good feeling they had brought to others' lives, extending to the littlest forgotten details. To some extent, this experience resembles purgatory. The Tibetan Buddhist understanding can be found in The Tibetan Book of The Dead, and is known as "Bardo Thodol" (the stage between life and afterlife).
