四分律刪繁補闕行事鈔 1.298

1.298

若作受戒之法，準律界外問難。若至乞受之時，十人叢坐，前結足開一人之分。必半身外界，亦準《十誦》、《善見》之文，足成僧數。此是定義。必依昔用，結界不成，作法非務，一生虛受，疑恒鎮心。所謂無戒滿世，此言驗矣。廣有廢立，如《義鈔》中。

If one performs the ordination procedure, according to the Vinaya, interrogation on impediments takes place outside the boundary. When it comes time to request receipt [of the precepts], the ten people sit gathered closely together, and when demarcating earlier, it was sufficient to leave room for one person. If half the body is outside the boundary, then according to the texts of the Daśādhyāya-vinaya and the Samantapāsādikā, this still suffices to complete the saṃgha quorum. This is the definitive principle. If one follows past practice, the demarcation of the boundary fails, the procedure performed is not a legitimate transaction, one receives [the precepts] in vain for one's whole life, and doubt will perpetually weigh upon one's mind. The saying that 'the entire world is devoid of precepts' is verified by this. Extensive discussions of what to discard and what to establish are as given in the Yichao.
