Yeshe Tsogyal (757–817), was the consort of the great Indian tantric teacher Padmasambhava, the founder-figure of the Nyingma tradition of Tibetan Buddhism. Nyingma tradition considers her equal in realization to Padmasambhava himself. The meditational practices related to her, stress her enlightened aspect, and are similar in form to tantric deity practices in general. She is variously equated with Vajravārāhī, Tārā or Sarasvatī.
Both the Nyingma and Karma Kagyu schools of Tibetan Buddhism recognize Yeshe Tsogyal as a female Buddha. The translators of Lady of the Lotus-Born, the namthar or spiritual biography that Yeshe Tsogyal left as a terma observe:
As Dodrup Tenpai Nyima makes clear, beings able to reveal Termas must have at least the realization of the Perfection Stage practices. On the other hand, the one who originates the Treasures must have the supreme attainment of Buddhahood. Lady of the Lotus-Born is thus a testimony of Yeshe Tsogyal's enlightenment.
