Vajradhara Niguma

Vajradhara Niguma (born 1025) is the full Tibetan name of the Indian yogini Vimalashri; sister, lover and student of Naropa, a Mahasiddhas and once the head of the famous Nalanda University.

Naropa taught different things to each of his students, and Niguma received the teachings that became known as the Nigu Chos-drug. Once Niguma herself had reached enlightenment, she began to pass her knowledge on to others. Her most famous disciple was the Tibetan yogi and Bönpo Khyungpo Naljor, the only one to whom she imparted her most secret teachings. Therefore, the Shangpa school, although officially founded by Khyungpo Naljor, is in fact based on this transmission from Niguma.
