"When I observed that by the performance of certain actions, unwholesome factors increased and wholesome factors decreased, then that form of bodily action was to be avoided. And when I observed that by the performance of such actions unwholesome factors decreased and wholesome ones increased, then such bodily action was to be followed. ... The same applies to conduct of speech and the pursuit of goals."
