1-12.
The Twelve Discourses Beginning with Strenuous Deeds
673-684. "Just as, monks, whatever activities requiring strength are done, all of them are done in dependence on earth, established upon earth, thus these activities requiring strength are done; just so, monks, a monk, in dependence on morality, established upon morality, develops the four right strivings, cultivates the four right strivings. And how, monks, does a monk, in dependence on morality, established upon morality, develop the four right strivings, cultivate the four right strivings? Here, monks, a monk generates desire for the non-arising of unarisen evil unwholesome mental states, he strives, arouses energy, exerts the mind, and strives, etc. he generates desire for the presence, non-decay, increase, expansion, development, and fulfilment of arisen wholesome mental states, he strives, arouses energy, exerts the mind, and strives. Thus, monks, a monk, in dependence on morality, established upon morality, develops the four right strivings, cultivates the four right strivings." The twelfth.
