His students include Drikung Khandro, Khenpo Konchok Gyaltsen, Lamkhen Gyalpo Rinpoche and the 14th Dalai Lama of Tibet.^[3] Although the Dalai Lama had other highly qualified teachers and debate partners for religious matters, he used to clarify philosophical concepts in discussions with Khunu Lama.^[1]Among several teachings that the Dalai Lama received from Khunu Rinpoche was the celebrated Bodhisattvacaryāvatāra or Guide to the Bodhisattva's Way of Life by Shantideva. The Dalai Lama called him the "Shantideva of our time."^[1] and often mentions him when teaching.

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.^[4]

He died at Shashur Monastery in Lahaul and Spiti district of Himachal Pradeshat the age of 82 on February 20, 1977.^[1]
