"A-Tri (A-Khrid), literally “The Guidance of the Primordial State” is one of the three principal Dzogchen (Great Perfection) traditions within Bön. It was founded in the 11th century by Ritro Chenpo (1038-1096), known simply as “the holy man,” who systematized previous teachings and added his own mind-treasures to create a succession of eighty practices. These were later organized into thirty sessions and finally during the 13th century condensed into a practice manual of fifteen sessions by the renowned lama Drugyalwa Yungdrung. Over the next two years Tenzin Wangyal Rinpoche will offer comprehensive teachings and practice instruction from Drugyalwa’s text “The Fifteen Stages of Practice that Guide One to the Primordial State.” These stages begin with preliminary practices to ripen the consciousness and progress through practices to stabilize the mind and directly realize its true nature.".....
There are three requirements before a student may begin a practice:
1. the empowerment (Tibetan: wang)
2. a reading of the text by an authorized holder of the practice (Tibetan: lung)
3. instruction on how to perform the practice or rituals (Tibetan: tri).
An individual is not allowed to engage in a deity practice without the empowerment for that practice. The details of an empowerment ritual are often kept secret as are the specific rituals involved in the deity practice.

The Stages of A-Khrid Meditation (Dzogchen Practice of the Bon Tradition)...by Bru-sgom rGyal-ba g.young-drung, Translated by Per Kvaerne and Thupten K. Rikey...the A-khrid is held to have an historical origin which can be precisely defined, being initiated by the lama known as rMe'u dGongs-mdzod, 'the Great Hermit' of the rMe'u clan, who lived from 1038 to 1096.....A-Khrid was promulgated by the great hermit, dGongs-mdzod (1038-1096). His system is divided into 80 periods called A-khrid thu-mtshams brgyad-cu-pa, each period lasting one or two weeks. After completing this course the adept is qualified and given the title rTogs-ldan. However, the system of 80 periods was reduced to 30 by 'A-aha Blo-gros rgyal-mtshan (1198-1263) and a little later this was further reduced to 15 by Bru Rgyal-ba g. young-drung (1242-1290).

"Publications (other than texts in Tibetan) relevant to the Great Perfection of Bon have not been numerous. Brief excerpts from texts belonging to the Zhang zhung snyan rgyud and the bsGrags paskor gsum traditions were translated by Giacomella Orofino in 1985: Insignamenti tibetani su morte e liberazione. Testi inediti dale piuantiche tradizioni del Tibet, Roma (Edizioni Mediterranee); English revised edition 1990. A short but important contribution was Chap. VIII, "rDzogs chen in the Bonpo Tradition", in Samten G. Karmay, The Great Perfection. A Philosophical and Meditative Teaching of Tibetan Buddhism, Leiden (E.J. Brill), 1988, pp. 201-205.....In 1993 two books on this topic appeared. Tenzin Wangyal, a Geshe from the Bonpo Monastery at Ochghat, Himachal Pradesh, presented the Great Perfection according to his own training and experience in Wonders of the Natural Mind. The Essence of Dzogchen in the Native Bon Tradition of Tibet, Barrytown, N.Y. (Station Hill Press). The other book, entitled Heart Drops of Dharmakaya. Dzogchen Practice of the Bon Tradition, Ithaca, N.Y. (Snow Lion Publications), is a composite volume. The main part of the book is a somewhat free English rendering of a work by the famous Bonpo lama Shar-rdza bKra-shis rgyal-mtshan (1859-1934), with the comments (based on tape-recordings) of Slob dpon bsTan-'dzin rnam-dag, an essay on the phenomenon of the 'rainbow body' ('ja' lus), a short history of Bon, illustrations, Tibetan text, a preface by the editor of the volume, Richard Dixey, and a short Introduction and a Bibliographic Essay by myself. An article on the A-khrid which I published in 1983 is reprinted as the Introduction to the present volume."....http://www.exoticindiaart.com/book/details/stages-of-khrid-meditation-dzogchen-practice-of-bon-tradition-IDK349/
