"There are two kinds of educational systems. One deals with transcendental knowledge [parA vidyA] and the other with material knowledge [aparA vidyA]. All the Vedas — the Rg Veda, Yajur Veda, SAma Veda and Atharva Veda, along with their corollaries, known as ZikSA, kalpa, vyAkaraNa, nirukta, chanda and jyotiSa — belong to the inferior system of material knowledge [aparA vidyA]. By parA vidyA one can understand the akSara — Brahman or the Absolute Truth." (MuNDaka UpaniSad 1.1.4–5)
