Pramāṇa and prameya are two words constantly met with in Hindu epistemo-logy. Pramāṇa is the means of knowledge and prameya is that which is thus known. For instance, when we see a pot, the act of seeing is the ‘pramāṇa’ and the pot itself is the ‘prameya’ (that which is measured or comprehended).

All objects with name, form and qualities can be subject to comprehension and verification through the pramāṇas. However, God the transcendental Being, is beyond all such pramāṇas and hence is termed ‘Apraymeya’ (lit., the immeasu-rable). He is beyond even the śāstra or āgama (the revealed scripture) which helps only in removing our miscomprehension about him and not reveal him directly.

In devotional literature, the word seems to be more commonly applied to Lord Viṣṇu.
