"Whenever you want to perform a verbal act, you should reflect on it: 'This verbal act I want to perform — would it lead to self-affliction, to the affliction of others, or to both? Is it an unskillful verbal 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 verbal act with painful consequences, painful results, then any verbal 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 verbal action with happy consequences, happy results, then any verbal act of that sort is fit for you to do.
"While you are performing a verbal act, you should reflect on it: 'This verbal act I am doing — is it leading to self-affliction, to the affliction of others, or to both? Is it an unskillful verbal act, with painful consequences, painful results?' If, on reflection, you know that it is leading to self-affliction, to the affliction of others, or to both... you should give it up. But if on reflection you know that it is not... you may continue with it.
"Having performed a verbal 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 verbal 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 verbal action with happy consequences, happy results, then you should stay mentally refreshed and joyful, training day and night in skillful mental qualities."
