僧羯磨 1.32

1.32

難結小界授戒法（時有欲受戒者至界外，六群比丘往遮。佛言：「汝等善聽！自今已去，不同意者未出界，聽在界外疾疾一處集結小界。」應如是作。）

The procedure for demarcating a small sīmā in times of hardship to bestow the precepts. (At that time, there was one who wished to receive the precepts and arrived outside the sīmā, but the ṣaḍvargika-bhikṣus went to obstruct it. The Buddha said: "Listen well, all of you! From this day forth, if those of differing views have not yet left the sīmā, I allow you to gather swiftly in one place outside the sīmā and demarcate a small sīmā." It should be performed thus.)
