If these three, viz., the Vedas, direct perception and behaviour (or mental purity) together form what is to be considered as authority, it can be alleged that there is difference between each. Virtue then becomes really of three kinds although it is one and indivisible.
वेदः प्रत्यक्षमाचारः प्रमाणं तत्रयं यदि। पृथक्त्वं लभ्यते चैषां धर्मश्चैकस्त्रयं कथम्॥
