2.3
“Bhikkhus, there are these two things that cause regret (torment, cause remorse). What are the two? Here, bhikkhus, a certain person has engaged in bodily misconduct but has not engaged in good bodily conduct; has engaged in verbal misconduct but has not engaged in good verbal conduct; has engaged in mental misconduct but has not engaged in good mental conduct. He regrets, ‘I have engaged in bodily misconduct’; he regrets, ‘I have not engaged in good bodily conduct’; he regrets, ‘I have engaged in verbal misconduct’; he regrets, ‘I have not engaged in good verbal conduct’; he regrets, ‘I have engaged in mental misconduct’; he regrets, ‘I have not engaged in good mental conduct.’ These, indeed, bhikkhus, are the two things that cause regret.”
