Commentary on the Essence Manual of Instructions

from The Light of Wisdom (ISBN 9627341371), vol.1, pp. xvi-xvii:

One of the principle recipients of the Lamrim Yeshe Nyingpo was the second prince, known variously under the names Yeshe Rolpa Tsal, Munrub Tseypo, or Mutri Tsyepo. An untitled and unpublished manuscript written by His Holiness Dilgo Khyentse Rinpoche explaining the Sheldam Nyingjang, herein called Commentary on the Essence Manual of Instructions, contains sme background information on this prince:

• The single father, King Trisong Deutsen, had three sons of which the middle one was called Munrub Tseypo, a lord of the tenth bhumi who actually and visibly had achieved the noble qualities of abandonment and realization. Also known as the Prince Translator, he reached perfection in learning. At the end, his bodily form vanished into the body of light, and he attained the supreme accomplishment of perceiving the primordial wakefulness. It is his magical reincarnation who appeared during this age of degeneration, renowned worldwide under the title Orgyen Chokgyur Dechen Shikpo Lingpa, the universal ruler over an ocean of accomplished revealers of Dharma treasures (terton).
