25. Let him who cultivates self-restraint and longs for blessed purity - which could rightly be called dispassion - discipline the flesh and bring it into subjection, with humble thoughts invoking divine grace, and he will achieve the aim he desires. But he who feeds the body intemperately will be tormented by the demon of unchastity. Just as much water puts out a flame, so hunger or self-control combined with humility of soul extinguishes the fever of the flesh and of shameful fantasies.
