| frame | [[Dharmakirti]] Pramana (Skt. pramāṇa; Tib. ཚད་མ་, tsema, Wyl. tshad ma) is a Sanskrit term, the primary meaning and most common translation of which is 'valid cognition', meaning the correct knowledge of a particular object.

The standard definition of pramana is “a non-deceptive cognition” (Skt. avisaṃvādi-jñāna; Tib. མི་བསླུ་བའི་ཤེས་པ་, Wyl. mi bslu ba'i shes pa). There is some debate, particularly amongst Tibetan commentators, as to whether the definition should also specify that a valid cognition realizes something anew (Tib. གསར་དུ་རྟོགས་པ་, Wyl. gsar du rtogs pa).<ref>For more information see Dreyfus (1997), pp. 366-378 passim</ref>

In Mipham Rinpoche's tradition, valid cognition is often divided into conventional valid cognition and absolute valid cognition and these categories are then further subdivided into two:
