In Tibetan Buddhism and Bön, Zhitro () or Shitro zab-chos zhi khro dgongs pa rang grol, also known as kar-gling zhi-khro refers to a cycle of teachings revealed by the terton Karma Lingpa and traditionally believed to have been written by Padmasambhava. The practices involve a mandala of 100 peaceful (zhi) and wrathful (khro) tantric deities and associated teachings and tantric practices which focus on those deities which represent the purified elements of the body and mind. These hundred peaceful and wrathful deities are believed to manifest to a deceased person following the dissolution of the body and consciousness whilst they are in the intermediate state, or bardo, between death and rebirth. The Bardo Thodol, commonly known in the West as "The Tibetan Book of the Dead", forms one section of Karma Lingpa's Zhitro cycle. The Zhitro teachings are closely related to the Guhyagarbha Tantra and are considered an Inner Tantra.

The Zhitro mandala teachings were found in the same terma collection as the Bardo Thodol, a text well known in the West as The Tibetan Book of the Dead. The Dzogchen practice of Zhitro involves viewing the body as a mandala of both peaceful and wrathful deities, the inclusivity promoting awareness in the practitioner of the universality of Buddha-nature. As a subtle body practice using yogic practices to manipulate the lung, or subtle-winds, of the body, this is a completion stage practice of the Inner Tantras. The Lion's Roar Tantric Glossary describes the Zhitro mandala practice: Zhi-khro is a practice of Tibetan Buddhism involving visualizing the body as a composite of the 100 peaceful and wrathful deities. In the practice, the deities are first visualized in mandalas of 42 peaceful and 58 wrathful deities centered in the heart, throat and crown chakra, and then in all the channels and nadis of the body. Shugchang, et al. (2000) define and frame the Zhi-khro teachings in relation to the Inner Tantras, Anuyoga, Atiyoga, Guhyagarbha tantra, rigpa, Śūnyatā, non-duality, kye-rim, dzog-rim and bardo: The zhi-khro, which translates as the peaceful and wrathful deities, is considered part of the inner tantra.
