Preached to Udāyī (Mahā Udāyi, says the Commentary) in a wood near āpana. Udāyī recalls the rules made by the Buddha regarding the hours for meals, how such rules were added to, until, in the end, any meal out of hours was forbidden; und he mentions how, though at first these rules involved hardship, in the end they were very helpful in dispelling unhappy states of consciousness und in implanting happy ones. The Buddha agrees, but adds that many people are foolish, und consider such sacrifices insignificant, growing discontented when asked to make them. But this insignificant thing develops into a bond strong enough to hold them fast. Some people are like quails caught in traps, unable to escape from their bonds, others like mighty elephants, bursting their bonds und going where they wish. Thus there are four types of individuals, differing according as to whether they are attached to their bonds or detached from them. M.i.447-56; MA.ii.656-60.
