Yeshe Tsogyal, VIII century, also known as "Victorious Ocean of Wisdom" was the Mother of Tibetan Buddhism or Mother of Knowledge.
Her life story recounts her very tangible struggles on the path and her ultimate victory—overcoming dualistic thought and compassionately benefiting countless beings. As a teacher, she uses her own life story to instruct and nurture her disciples so they can learn how to attain their own enlightenment.
On this portrait she appears as a form of red wisdom.
