四分律比丘含注戒本 3.442

3.442

佛在釋翅瘦國。時，象力釋子善能論議，得外道切問，前後相違，僧中亦爾。比丘以事白佛，佛言：「僧應白四與彼羯磨，治取本罪，奪三十五事。若伏首本罪者，應白四羯磨如法為解。」故立此法。有本為「覓罪相」者，意同如上。而次第六，滅覓諍上品藥故。

The Buddha was in the country of the Śākyas. At that time, the Śākyan Hastibala was skilled at debate. Receiving sharp questioning from non-Buddhists, his earlier and later statements contradicted each other, and it was also like this within the Saṃgha. The bhikṣus reported the matter to the Buddha, and the Buddha said, “The Saṃgha should carry out a karman with one motion and three announcements against him, dealing with him on the basis of his original offense, and depriving him of thirty-five privileges. If he admits his original offense, one should carry out a karman with one motion and three announcements to resolve it in accordance with the Dharma.” Therefore this rule was established. Some texts have ‘seeking the marks of guilt’; the meaning is the same as above. It is sixth in sequence because it is the supreme medicine for settling disputes of investigation.
