English: The ancient and medieval Indian schools of philosophy call epistemology as Pramanas.

Different schools consider different number of epistemic means to correct knowledge, between one of Charvaka school to six of Advaita Vedanta: Pratyakṣa (perception), Anumāṇa (inference), Upamāṇa (comparison and analogy), Arthāpatti (postulation, derivation from circumstances), Anupalabdi (non-perception, negative/cognitive proof) and Śabda (word, testimony of past or present reliable experts).
