Jonangpa (Tibetan, jo nang pa). The Tibetan Buddhist school expounding the view of extrinsic emptiness, which was founded by Yumo Mikyo Dorje (Tibetan, Yu-mo mi-bskyod rdo-rje) in the 11th century, named after the location of its chief monastery. Subsequent lineages developed through Dolpopa Sherap Gyeltshen (Tibetan, Dol-po-pa shes-rab rgyal-mtshan), Tāranātha, and others. The Jonangpa were often viewed with suspicion by adherents of the other schools for their controversial theories, such as their interpretation of the embryonic tathāgata (tathāgata-garbha) as a real essence enjoying a form of self-established being like a permanent self (atman). Remnants of the Jonangpa school still survive in Tibet today although they were severely suppressed during the reign of Dalai Lama V.
