Other-emptiness (shentong): ultimate reality is empty of what is other than itself, Beliefs & Restrictions
Standing
Concerns Point in Dispute
Currently States Proponents hold that a purely negative emptiness cannot account for what the tantras say is realised; opponents hold that the position smuggles a permanent self back in under another name.
Other-emptiness, shentong, the distinctive teaching of the Jonang tradition and read in comparable terms by the Karma Kagyu after the Third Karmapa, holds that ultimate reality, the buddha nature spoken of in the third turning of the wheel of teaching, is empty of the adventitious defilements that are other than it, but is not itself empty of its own luminous nature. Cyrus Stearns's study of the Jonang master Dolpopa Sherab Gyaltsen, who gave the teaching its most developed form in the fourteenth century, records that proponents hold a purely negative account of emptiness cannot explain what the tantras describe as actually realised in meditation, while opponents, chiefly the Gelug tradition, hold that positing a nature not itself empty smuggles a permanent self back into the teaching under another name. The dispute was severe enough that the teaching and its textual tradition were suppressed in central Tibet for centuries, with the Jonang lineage surviving at a distance from the center of Tibetan religious authority. The disagreement remains unresolved because it concerns how to read the same third-turning scriptures both sides accept as authoritative, and neither side's reading has been shown to be textually impossible.
