Chetsun Senge Wangchuk
Chetsun Senge Wangchuk is counted among the lineage gurus in the transmission of Nyingtig which he received from his root guru Dangma Lhungyal as well as from Vimalamitra directly. As a result of his high level of realization, his physical body disappeared in rainbow light at the time of death. Before passing away, he uttered this last song. His later reincarnation as Jamyang Khyentse Wangpo remembered the Dzogchen teachings which Senge Wangchuk had transmitted to the dakini Palgyi Lodro and wrote them down as the terma Chetsun Nyingthig, one of the most important Dzogchen instructions based on the transmission from Vimalamitra.
