Xitro

In Tibetan Buddhism and Bön, Zhitro (Tibetan; Wylie: zhi khro, alternate phonetic transcription: shitro, xitro) or Karling Zhitro (kar gling zhi khro, after Karma Lingpa, the treasure-revealer who (re)discovered it) is the name of a genre of scripture and associated tantric practices primarily concerned with the "Hundred Peaceful and Wrathful Deities". The best-known (though by no means only) example of this genre is "The Great Liberation by Hearing in the Intermediate State," better known in the west as "The Tibetan Book of the Dead".
