Niguma is considered as one of most important and highly appreciated tantric yogini or Vajrayana Buddhist lady- teachers (dakinis). Only few facts are known about her life. She was born into a rich Brahmin family in Kashmir in the 10th century and according to different sources was the sister or consort of Naropa. It is said that her Buddhist realization originates directly from Buddha Vajradhara. Her main student was the Tibetan meditation master Khyungpo Naljor, who traveled to India to receive transmission of her teachings. Later on he became the founder of the Shangpa Kagyu lineage.
