6.8

tisro vṛttaya iti prayoktavye trīṇi vṛttaya iti cchāndasaḥ prayogaḥ/ tatra vidhīyamānam upāyaphalaṃ lābhaḥ/ jñānatapodevanityatvasthitiśuddhibhedāt pañcavidhaḥ/ tad āha haradattācāryaḥ —

The employment in the above line of the neuter numeral three (trīṇi), instead of the feminine three (tisraḥ), is a Vedic construction.

(a.) Acquisition is the fruit of an expedient while realising, and is divided into five members, viz., knowledge, penance, permanence of the body, constancy, and purity. Thus Haradattācārya says: Knowledge, penance, permanence, constancy, and purity as the fifth.
