Rahula: For reflection, sir.

The Buddha: In the same way, Rahula, bodily acts, verbal acts, and mental acts are to be done with repeated reflection.

Whenever you want to perform a bodily act, you should reflect on it: 'This bodily act I want to perform-would it lead to self-affliction, to the affliction of others, or to both? Is it an unskillful bodily act, with painful consequences, painful results?' If, on reflection, you know that it would lead to self-affliction, to the affliction of others, or to both; it would be an unskillful bodily act with painful consequences, painful results, then any bodily act of that sort is absolutely unfit for you to do. But if on reflection you know that it would not cause affliction...it would be a skillful bodily act with happy consequences, happy results, then any bodily act of that sort is fit for you to do.
(Similarly with verbal acts and mental acts.)

While you are performing a bodily act, you should reflect on it: 'This bodily act I am doing-is it leading to self-affliction, to the affliction of others, or to both? Is it an unskillful bodily act, with painful consequences, painful results?' If, on reflection, you know that it is leading to self-affliction, to affliction of others, or both...you should give it up. But if on reflection you know that it is not...you may continue with it.
(Similarly with verbal acts and mental acts.)

Having performed a bodily act, you should reflect on it....If, on reflection, you know that it led to self-affliction, to the affliction of others, or to both; it was an unskillful bodily act with painful consequences, painful results, then you should confess it, reveal it, lay it open to the Teacher or to a knowledgeable companion in the holy life. Having confessed it...you should exercise restraint in the future. But if on reflection you know that it did not lead to affliction...it was a skillful bodily act with happy consequences, happy results, then you should stay mentally refreshed and joyful, training day and night in skillful mental qualities.
(Similarly with verbal acts.)

Having performed a mental act, you should reflect on it....If, on reflection, you know that it led to self-affliction, to the affliction of others, or to both; it was an unskillful mental act with painful consequences, painful results, then you should feel horrified, humiliated, and disgusted with it. Feeling horrified... you should exercise restraint in the future. But if on reflection you know that it did not lead to affliction...it was a skillful mental act with happy consequences, happy results, then you should stay mentally refreshed and joyful, training day and night in skillful mental qualities.

Rahula, all the priests and contemplatives in the course of the past who purified their bodily acts, verbal acts, and mental acts, did it through repeated reflection on their bodily acts, verbal acts, and mental acts in just this way.

All the priests and contemplatives in the course of the future...All the priests and contemplatives at present who purify their bodily acts, verbal acts, and mental acts, do it through repeated reflection on their bodily acts, verbal acts, and mental acts in just this way.
Therefore, Rahula, you should train yourself: 'I will purify my bodily acts through repeated reflection. I will purify my verbal acts through repeated reflection. I will purify my mental acts through repeated reflection.' Thus you should train yourself.
That is what the Blessed One said. Pleased, Ven. Rahula delighted in the Blessed One's words.
