Virupa (c.7th -8th cce) Dharma brother of Santideva at Nalanda, among the most outstanding of the Mahasiddhas, the first human Vidyadhara of an important Hevajra lineage transmitted by Vajradhara. His teachings were widely disseminated in India and propogated in Tibet during the second wave of transmission. After 12 years of practice he had a vision of Vajravarahi which inspired his eventual realization. Certain episodes in his life are associated with the emanation of Guru Nyima Odzer.
Vajravarahi: Dorje Phakmo, the Diamond Sow, a fierce aspect of Vajrayogini, regarded as the queen of the dancing, wrathful dakinis. Vajravarahi represents passion and compassion, and ignorance as well as the wisdom of the all-encompassing matrix from which all phenomena unfold. She appeared to Padmasambhava in The Rugged Forest of Parushakavana charnel ground, and blessed him.
