In Tibetan Buddhism, Vajravārāhī ("The Diamond Sow", Tibetan: ་རྡོ་རྗེ་ཕག་མོ, Wylie: rdo rje phag mo Dorje Pakmo) is a wrathful form of Vajrayogini associated particularly with the Cakrasaṃvara Tantra, where she is paired in yab-yum with the heruka Cakrasaṃvara. Judith Simmer-Brown writes that "Vajravārāhī's iconography is very similar to that of Vajrayoginī, but she often has more prominent fangs and a more wrathful expression, and she prominently displays a sow's head above her right ear."
