Chetsün Sengé Wangchuk
Chetsün Sengé Wangchuk (lce btsun seng ge dbang phyug) (11–12th century) was an important figure in the Nyingtik lineage. Vimalamitra appeared to him and gave him empowerments, guidance and instructions, and at the age of one hundred and twenty-five, he vanished into the sky in a cloud of rainbow light. Before passing away, he gave his last instructions to the dakini Palgyi Lodrö. He was reincarnated as the great nineteenth century master Jamyang Khyentse Wangpo, who, recollecting his past life in a vision and receiving the teaching back from the dakini, brought out the very important cycle of teachings known as Chetsün Nyingtik.
