Real austerity is based upon these three principles:
- First, take refuge in the truth. Truth is the pillar to which you must always hold while performing any action.
- Second, conquer lust.
- Third, renounce all cravings.
Observe these three principles. That is real austerity, and the greatest of these is to conquer lust.
