[203] "'Bhikkhus, I say that verbal conduct (vacīsamācāra) is twofold: that which should be cultivated and that which should not be cultivated; and the one is verbal conduct distinct from the other' — thus indeed was this said by the Blessed One. And in dependence on what was this said? Venerable sir, such verbal conduct as, when one cultivates it, causes unwholesome states (akusalā dhammā) to increase and wholesome states (kusalā dhammā) to diminish — verbal conduct of such a kind should not be cultivated. But such verbal conduct as, when one cultivates it, causes unwholesome states to diminish and wholesome states to increase — verbal conduct of such a kind should be cultivated."
