Kalasiddhi was one of the five principal consorts of Guru Rinpoche, an emanation of Vajravarahi‘s enlightened qualities. She was born in Nepal into the family of weavers. Her parents, Bhadana and Nagini, named their child Dakini, as she was endowed with all the signs of a khandro. When her mother died, her father abandoned her in the charnel ground. There she was discovered by Mandarava, who, in the form of a tigress, suckled her and kept her alive.
She grew up and managed to earn her living as a spinner and weaver of cotton. When Yeshe Tsogyal was on her second visit to Nepal, she came across the fourteen-year old girl, took her as her disciple and gave her name Kalasiddhi (kala meaning “humors” or “bodily essences”), because she was indeed a dakini of the “Body lineage” and was to attain accomplishment in the Mantrayana. In Mangyul, across the Tibetan border upstream of the Trisuli-kola, Kalasiddhi received initiation into the Tantra Lama Mandala and after extensive meditation gained siddhi.
Later she accompanied Yeshe Tsogyal to Tibet’s first Buddhist monastery, Samye, and to the Guru Pema’s retreat place at Chimphu. There she became his consort to further the diffusion of Mantrayana in Tibet. When Guru Pema left for the Southwest, Kalasiddhi was left in Yeshe Tsogyal’s care and received transmission of her final profound Mantrayana instruction.
