Pramāṇa is a central concept of Indian epistemology: a source of true knowledge. The schools accept different numbers, from perception alone to six, including perception, inference, comparison, testimony, postulation and non-apprehension. Vedānta holds that Brahman is known through the testimony of scripture, which then becomes direct.
