四分律刪繁補闕行事鈔 1.332

1.332

二擯出者。謂對俗人倒說四事，廣如律文；又如〈隨戒〉中污家惡行。倒亂佛法，污他俗人淨善之心，以非為是。故須遣出本處，折伏治之。使世俗識非達正，無復疑惑。此之過罪，人多有之，特須禁斷。若論治法，隨順及以解辭，略同上法。然初擯中，牒其過已，離此住處為異。律本委具。若隨順乞解，不得輒來；當在界外遣信來請。《僧祇》云：不得共諸比丘語論。若有咨請，推屬本師。

Second, banishment. This refers to expounding the four matters perversely in front of laypeople, as detailed in the Vinaya text; or like corrupting households with bad conduct in the 'Subsequent Precepts'. Subverting and disrupting the Buddha's Dharma, defiling the pure and good minds of other laypeople, taking what is wrong to be right. Therefore, he must be dispatched out of his original dwelling and brought under discipline to subdue him, so that laypeople may recognize wrongs, understand what is correct, and have no further doubts. This transgression is committed by many people and especially must be prohibited. Regarding the disciplinary procedure, compliance, and words of revocation, they are roughly the same as the method above. However, in the initial banishment, after citing his fault, making him leave this dwelling is what is different. The Vinaya root text contains it in detail. If he complies and requests revocation, he must not come unannounced; he should remain outside the boundary and send a messenger to request it. The Mahāsāṃghika-vinaya states: He must not discuss or converse with the bhikṣus. If he has inquiries or requests, refer them to his original preceptor.
