Editing Bon (section)

=== Termas ===
The largest part of the Bon canon is made up of numerous [[Terma (religion)|termas]] (treasure texts), which were believed to have been hidden away during the period of persecution and to have begun to be discovered during the 10th century.<ref name=":14"/> Bonpos hold that their termas were hidden by masters like [[Drenpa Namkha]] during the period of decline and persecution under [[King Trisong Detsen]], and then were rediscovered by later Bon tertons (treasure discoverers).<ref name="Powers 2007, p. 510"/>

The three principal terma of Yungdrung Bon are:<ref name="google171">M. Alejandro Chaoul-Reich (2000). "Bön Monasticism". Cited in: [[Will Johnston|William M. Johnston]] (author, editor) (2000).

Three Bon scriptures—''mdo <nowiki>'</nowiki>dus'', ''gzer mig'', and ''gzi brjid''—relate the mythos of [[Tonpa Shenrab Miwoche]]. The Bonpos regard the first two as ''[[terma (religion)|gter ma]]'' rediscovered around the tenth and eleventh centuries and the last as ''nyan brgyud'' (oral transmission) dictated by Loden Nyingpo, who lived in the fourteenth century.<ref>[[Samten Karmay|Karmay, Samten G]].

''A Cavern of Treasures'' ({{bo|t=མཛོད་ཕུག|w=mdzod phug}}) is a Bon [[terma (religion)|terma]] uncovered by Shenchen Luga ({{bo|t=གཤེན་ཆེན་ཀླུ་དགའ|w=gshen chen klu dga'}}) in the early 11th century which is an important source for the study of the [[Zhang-Zhung language]].<ref>{{cite book|last=Berzin|first=Alexander|url=http://studybuddhism.com/en/advanced-studies/abhidharma-tenet-systems/comparison-of-buddhist-traditions/the-four-immeasurables-in-hinayana-mahayana-and-bon|title=The Four Immeasurable Attitudes in Hinayana, Mahayana, and Bon|website=studybuddhism.com|year=2005|access-date=June 6, 2016}}</ref>

The main Bon great perfection teachings are found in terma texts called ''The Three Cycles of Revelation''. The primary Bon Dzogchen text is ''The Golden Tortoise'', which was revealed by Ngödrup Drakpa (c. 11th century). According to Samten Karmay, these teachings are similar to those of the [[Semde]] class in Nyingma.<ref>Powers 2007, p. 510.</ref> According to Jean Luc Achard, the main Dzogchen cycle studied and practised in contemporary Bon is ''The Oral Transmission of the Great Perfection in Zhangzhung'' (''rDzogs pa chen po zhang zhung snyan rgyud'')'','' a cycle which includes teachings on the Dzogchen practices of [[Trekchö|trekcho]] and [[Tögal|thogal]] (though it uses different terms to refer to these practices) and is attributed to the Zhangzhung sage [[Tapihritsa]].<ref>Achard, Jean-Luc (2017).
