Khunu Lama Tenzin Gyaltsen

Khunu Lama Tenzin Gyaltsen (Wylie: khu nu bla ma bstan 'dzin rgyal mtshan, 1894–1977), known also as Negi Lama Tenzin Gyaltsen (), was born in 1894 in the village of Sunam which lies in the forest-clad Kinnaur district of India in the western Himalayas. Khunu Rinpoche was neither a tulku nor a Buddhist monk but a layman (Wylie: dge bsnyen, Skt. upāsaka) who took the lay practitioner's vows .

He is renowned as one of the influential teachers in the Rimé (non-sectarian) movement within Tibetan Buddhism. A foremost scholar of Sanskrit and Classical Tibetan, Khunu Rinpoche traveled widely in Tibet and India disseminating essential teachings of Buddhist philosophy.

His students Drikung khandro ,Khenpo Konchok Gyaltsen, lamkhen Gyalpo Rinpoche include the 14th Dalai Lama of Tibet. Although the Dalai Lama had other highly qualified teachers and debate partners for religious matters the philosophical concepts which seemed still not clear enough to him he used to discuss with Khunu Lama. Among several teachings that the Dalai Lama received from Khunu Rinpoche was the celebrated Bodhisattvacaryāvatāra of Shantideva. The Dalai Lama called him the “Shantideva of our time”.

His seminal work on bodhicitta was translated and published under the title of "Vast as the Heavens, Deep as the Sea: Verses in Praise of Bodhicitta" by Wisdom Publications in 1999.

He died at Shashur Monastery in Lahaul and Spiti district of Himachal Pradesh at the age of 82 on February 23, 1977.

Two reincarnations of Khunu Lama have been identified, both of whom are teachers in the Buddhist tradition. Jangchhub Nyima was born to a Tibetan father and Danish mother and currently teaches in India and Denmark. Tenzin Priyadarshi was born into a family of Brahmin parents in Bihar, India and is known for his continued interest in Sanskrit Buddhist literature and was the first Buddhist Chaplain at the Massachusetts Institute of Technology.
