punyam

As the verb â-kar takes karman for its object (punyam karmâ karati, &c.), and as the separate denotation (i.e. the use of apparently equivalent words, viz. âkar and karman) can be accounted for on the ground that one of them refers to works established by manifest texts, and the other to texts inferred from actually existing rules of good conduct; and as, when the primary meaning is possible, no secondary meaning must be adopted; nothing else but good and evil works (in the Vedic sense) are denoted by the word karana: such is the opinion of the teacher Bâdari.
