Dilgo Khyentse Rinpoche was a brilliant practitioner and teacher. He spent years in Tibet many of it in retreat in caves and escaped to Nepal in the 1960s. In Nepal he built a monastery with his wife and son (both also great practioners) and began teaching and giving empowerments from Remi Buddhist movement (the move to unify all major lineages of Tibet) to thousands of high lamas, monks, laypersons, and westerners. He was so prominent that when Dudjom Rinpoche passed away, he was asked to head the Nyingma Lineage. A 97 minute video of his life can be viewed on YouTube.com (under Dilgo Khyentse) showing his amazing life.

This book Brilliant Moon is the book that the video was based on.
