The twenty-first sutta of the Majjhima Nikáya, preached to Moliya-Phagguna, who was reported to the Buddha for frequenting the society of nuns and losing his temper when reproached therefor. A monk should not give way to anger even though he be sawn limb from limb with a two-handed saw (ubhatodandakena kakacena). The name of the sutta was given by the Buddha himself (M.i.122ff).
The sutta contains the story of the lady of Sávatthi, called Videhiká, who had a reputation for gentleness until tested by her servant girl and found wanting. The saw is only one of numerous similes which occur in the discourse. It is quoted in the Maháhatthipadopama Sutta (M.i.189), and is elsewhere (E.g., DA.i.123) given as an example of a sutta preached on account of someone's lack of patience.
