A legendary semi-historical figure who lived from CE 757 to CE 817, Yeshe Tsogyal (Tibetan, "Victorious Ocean of Wisdom") (Sanskrit, Jnanasagara), is considered to be one of the founders of Tibetan Buddhism. As a young girl, she is supposed to have prayed for the happiness of all sentient beings. At the age of sixteen, she was initiated into Buddhism by Guru Padmasambhava. Although she was originally one of the queens of Trisong Detsen , she was given to Padmasambhava and became his main spiritual consort. After many years of diligent study she achieved a level of enlightenment equal to his. Yeshe Tsogyal was the main compiler of Padmasambhava's teachings, and it was she who concealed most of the termas.
