四分律刪繁補闕行事鈔 2.487

2.487

律云：彼行覆藏者，應日三時，見清淨比丘。應作者，一切如法作，不應違逆。至布薩日，應掃灑布薩處，供給調度。乃至自在小房中住；有客來，遣出者，答云：不得二人共宿故。若眾僧分衣物，隨次取之。身在下行，坐在沙彌上。不得與清淨比丘共住、經行，同一床、一版；長床長版，作隔斷然後坐。乃至供給清淨比丘，如和尚法，文同故不出。《十誦》：極少四清淨比丘作別住。二別住人不得同一床坐。不得在屏處使，以客比丘來不見故。

The Vinaya states: That practitioner of [penance for] concealment should, at the three periods of the day, visit pure bhikṣus. Whatever is to be done, he must do entirely according to the Dharma, and must not disobey. When it comes to the day of the poṣadha, he should sweep and sprinkle the poṣadha site and supply necessary utensils. He may dwell freely in a small room; if a guest comes and sends him out, he replies: “Because two persons are not permitted to spend the night together.” If the Saṃgha distributes robes and goods, he takes them in turn. Physically he sits in the lower row, but sits above śrāmaṇeras. He is not permitted to dwell together with, perform walking meditation with, or share a bench or plank with pure bhikṣus; on a long bench or long plank, he must set up a partition before sitting. Up to serving pure bhikṣus like the protocol for an upādhyāya, because the text is identical, it is not set forth here. The Daśādhyāya-vinaya states: A minimum of four pure bhikṣus constitutes a parivāsa. Two persons undergoing parivāsa may not sit on the same bench. He must not be sent on errands in secluded places, lest a visiting bhikṣu arrives and does not see him.
