Nyak Luk Phurba
Nyak Luk Phurba (Wyl. gnyags lugs phur ba), or Vajrakilaya of Nyak Lotsawa, is a terma that was revealed by Dilgo Khyentse at Karma Gon. Dilgo Khyentse Rinpoche saw a scroll emerge from the sleeve of a statue of Gonpa Bernakchen (Mahakala of Kamtsang tradition), which contained the Nyak Luk Phurba teachings. Nyak Lotsawa, sometimes known as Nyak Jñanakumara, was one of the nine students closest to Guru Padmasambhava who perfected the practice of Vajrakilaya.
