Shelkar Dorje Tso

Shelkar Dorje Tso (Tib. ཤེལ་དཀར་རྡོ་རྗེ་མཚོ་) was one of Guru Rinpoche‘s primary Tibetan consorts.

According to Tulku Thondup, she crossed the Tsangpo river standing on a bamboo walking stick. She is counted among the previous incarnations of Sera Khandro, Khandro Tsering Chödrön, and Jetsun Jampa Chökyi.

In Pema Lingpa’s Lama Jewel Ocean collection there is an account of Namkhé Nyingpo meeting Dorje Tso as a result of a prophecy, taking her from her homeland in Shang Tanak, introducing her to the practice of Yangdak Heruka and offering her to Guru Rinpoche as a consort before she eventually attains realization through the practice of Yangdak and is able to fly through the sky.
