Chapter 17: The Divisions of Faith
sraddhaya paraya taptam
tapas tat tri-vidham naraih
śraddhayā—with faith; parayā—transcendental; taptam—executed; tapaḥ—austerity; tat—that; tri-vidham—three kinds; naraiḥ—by men; aphala-ākāṅkṣibhiḥ—without desires for fruits; yuktaiḥ—engaged; sāttvikam—in the mode of goodness; pari-cakṣate—is called.
This threefold austerity, practiced by men whose aim is not to benefit themselves materially but to please the Supreme, is of the nature of goodness.
