The Discourse on Making an Ardent Effort
50.
"Monks, ardour is to be done in three states.
With which three?
Ardour is to be done for the non-arising of unarisen evil unwholesome mental states, ardour is to be done for the arising of unarisen wholesome mental states, ardour is to be done for the endurance of arisen bodily feelings that are painful, sharp, rough, severe, disagreeable, unpleasant, and life-threatening.
Monks, ardour is to be done in these three states.
"When, monks, a monk makes ardour for the non-arising of unarisen evil unwholesome mental states, makes ardour for the arising of unarisen wholesome mental states, makes ardour for the endurance of arisen bodily feelings that are painful, sharp, rough, severe, disagreeable, unpleasant, and life-threatening. This is called, monks, a monk who is ardent, prudent, mindful, rightly for the making an end of suffering." The tenth.
