1. In Hinduism, proof, the means for attaining true knowledge.
2. In Buddhism generally, a school of thought established by Dignāga. In its more technical sense, however, pramāṇa refers to differing means of knowledge.
The Pramāṇa school appears to have centred on Nālandā; its other important exponent, a pupil of Dignāga, was Dharmakīrti. The works of both authors are still studied by Tibetan Buddhists.
