The Buddhist doctrine of the two truths (Sanskrit: dvasatya, Wylie: bden pa gnyis) differentiates between two levels of satya (Sanskrit; Pāli: sacca; meaning "truth" or "reality") in the teaching of Śākyamuni Buddha: the "conventional" or "provisional" (saṁvṛti) truth, and the "absolute" or "ultimate" (paramārtha) truth.
The exact meaning varies between the various Buddhist schools and traditions. The best known interpretation is from the Mādhyamaka school of Mahāyāna Buddhism, whose founder was the 3rd-century Indian Buddhist monk and philosopher Nāgārjuna. For Nāgārjuna, the two truths are epistemological truths. The phenomenal world is accorded a provisional existence. The character of the phenomenal world is declared to be neither real nor unreal, but logically indeterminable. Ultimately, all phenomena are empty (śūnyatā) of an inherent self or essence due to the non-existence of the self (anātman), but temporarily exist depending on other phenomena (pratītya-samutpāda).
