Zhangtön Tashi Dorjé (Wylie: zhang ston bkra shis rdo rje, c. 1097 – 1167) was a Tibetan Buddhist Dzogchen teacher who was an important treasure revealer (terton) in the Menngagde lineage of Dzogchen. He is particularly known for revealing the Vima Nyingthig, a key Dzogchen cycle of teachings which includes the Seventeen tantras of Dzogchen.[1] [2] [3] Zhangton was born in Yamdrok Tonang and was a disciple of Chetsün Sengé Wangchuk.[1] [4]
Traditional Nyingma histories hold that Zhangton had visions of Vimalamitra and discovered the Vima Nyingthig as a hidden treasure (terma) in Chimpu, Central Tibet.[5] Zhangton is also known for his authorship of The Great History of the Dzogchen Nyingtik (rdzogs pa chen po snying thig gi lo rgyus chen mo), a detailed chronological account of the Dzogchen tradition and lineage.[1] [6] Zhangton's main successor was his son Nyibum.
Some modern Tibetologists like David Germano and Christopher Hatchell think that Zhangton may have been the main author of the Vima Nyingthig.
