律戒本疏 1.71

1.71

[Rule] Eighteen: A monk on an upper story. Two visiting monks were living together in a two-story building. One room was on the upper floor; beneath the upper floor, [the other monk] was sitting in meditation. The monk on the upper floor exerted force when sitting down, so that the bedstead broke, the upper floor collapsed, and it injured the monk below. Whenever one sits or lies down, one should always do so calmly and slowly. Because these are the property of the saṃgha of the ten directions, because they are difficult to obtain, because [damaging them] hinders the practice of the Way, and because one fears disturbing the community, one must be composed and not damage beds or mats. Whoever sits or lies on the communal beddings without care violates this precept. If one supports [a bed] with hard objects such as wood or stone, with each leg [so supported], one commits a pāyattika; if supported with objects that are not hard, there is no offense.
