Chetsun Nyingtig
Chetsun Nyingtig (lce btsun snying tig). Vimalamitra One of the most important Dzogchen instructions, based on a transmission from Vimalamitra. Jamyang Khyentse had a vision of Chetsun Senge Wangchuk which inspired him to write the precious teaching known as Chetsun Nyingtig. Senge Wangchuk (11th-12th century) is among the lineage gurus in the Nyingtig transmission, which he received from his root guru, Dangma Lhungyal, as well as directly from Vimalamitra. As a result of his high level of realization, his physical body disappeared in rainbow light at the time of death. In a later reincarnation as Jamyang Khyentse Wangpo, he remembered the Dzogchen teachings which Senge Wangchuk had transmitted to the dakini Palgyi Lodro and wrote them down as the terma Chetsun Nyingtig, the 'Heart Essence of Chetsun.’
