Ayu Khandro (Long Life Dakini), also known as Dorje Paldrön, lived from 1839 to 1953. She was a practitioner, yogini, and terton of Tibetan Buddhism in Eastern Tibet. An accomplished Dzogchen meditator, she is renowned for her extensive pilgrimages throughout Tibet, long periods of dark retreat[1] practice, the gongter[2] of the practice of the yidam Senge Dongma (the Lion-Faced Dakini), various forms of Chöd,[3] and her lifelong dedication to spiritual practice.

The information we have about Ayu Khandro comes from the oral commentary that she personally gave to Chogyal Namkhai Norbu in Dzongsa, 1951. He wrote her namthar, or spiritual biography, which was later published in Women of Wisdom[4] by Tsultrim Allione.

Ayu Khandro met, and was taught by, many great masters of her day ; Jamyang Khyentse Wangpo,[5] Jamgon Kongtrul the First, Chokgyur Lingpa,[6] Nyala Pema Dündul, Adzom Drukpa,[7] Togden Rangrig and the ninth Tai Situpa, Pema Nyingche Wangpo.

She led the life of a hidden yogini, spending a significant amount of her life in retreat or as a wandering chodma.[8] She was recognised as an emanation of Vajrayogini.
