[257] Bhikkhus, there are these two powers. What two? The power of reflection (paṭisaṅkhānabala) and the power of development (bhāvanābala).
And what, bhikkhus, is the power of reflection? Here, bhikkhus, someone reflects thus: 'Misconduct by body (kāyaduccarita) has an evil result both in this very life and in the life to come; misconduct by speech (vacīduccarita) has an evil result both in this very life and in the life to come; misconduct by mind (manoduccarita) has an evil result both in this very life and in the life to come.' Having reflected thus, he abandons misconduct by body and develops good conduct by body; he abandons misconduct by speech and develops good conduct by speech; he abandons misconduct by mind and develops good conduct by mind; he maintains himself in purity. This, bhikkhus, is called the power of reflection.
And what, bhikkhus, is the power of development? Therein, bhikkhus, the power of development is a power of one in training (sekha). For, bhikkhus, relying on that trainee's power, one abandons lust (rāga), abandons hatred, abandons delusion. Having abandoned lust, having abandoned hatred, having abandoned delusion, one does not do what is unwholesome (akusala), one does not resort to what is evil. This, bhikkhus, is called the power of development. These, bhikkhus, are the two powers.
