Jetsunma Tenzin Palmo, one of the foremost living Buddhist nuns known for having lived twelve years in a remote Himalayan cave, discusses Reflections on a Mountain Lake: Teachings on Practical Buddhism. Jetsunma Tenzin Palmo is a bhikṣuṇī in the Drukpa Lineage of the Kagyu school of Tibetan Buddhism. At the age of twenty she traveled to India, becoming one of the first Westerners to be ordained as a Buddhist nun. The international bestseller Cave in the Snow chronicles her twelve years of seclusion in a remote cave. Deeply concerned with the plight of Buddhist nuns, she established Dongyu Gatsal Ling Nunnery in India. In 2008 His Holiness the Twelfth Gyalwang Drukpa, head of the Drukpa Kagyu lineage, gave her the rare title of Jetsunma (Venerable Master).
