四分律行事鈔資持記 1.1246

1.1246

難事小界。如〈結界〉中已明。難名通漫，略為簡示。受說安恣，竝以王賊水火等八難餘緣為難；增減說恣，即因他界鬪諍，來此為難；三小開者，竝以當界不和為難；緣相各別，不可混濫。（人多錯用，故此示之。）

A small boundary for difficult situations has already been clarified in the chapter on 'Establishing Boundaries.' The term 'difficulties' is broad and vague, so it is briefly distinguished here. The reception [of ordination], poṣadha, retreat, and pravāraṇā all take the eight difficulties of king, thieves, water, fire, etc., and other conditions as difficulties. The addition and reduction of poṣadha and pravāraṇā are difficulties caused by quarrels in another boundary coming here. The three small boundaries take disharmony within the boundary as the difficulty. The characteristics of the conditions are distinct and must not be confused. (Many people use them incorrectly, which is why this is shown.)
