五明

pañca-vidyā, the five sciences or studies of India:

(1) śabda, grammar and composition; śilpakarmasthāna, the arts and mathematics; cikitsā, medicine; hetu, logic; adhyātma, philosophy, which Monier Williams says is the 'knoowledge of the supreme spirit, or of ātman', the basis of the four Vedas; the Buddhists reckon the Tripiṭṭaka and the 十二部教 as their 內明, i. e. their inner or special philosophy.
