3.305

二問主人受房等。律云：問舊比丘，我若干歲，有房分不？答言有者，應問有人住不？若無人者，當問有臥具、若被、若利養、若器物、若房衣等？有者當取。至房所，開戶已，出床褥等，淨掃地。若得針線、刀子、乃至一丸藥，舉之；有主識，當與。如是治除屋內已，還內臥具復本處竟。問何處大小行、淨地、不淨地、佛塔、聲聞塔、第一上座房、乃至第四上座房等，一一別問；若不問者，主人一一示語，乃至云此是唾器、小便器等。《五分》：住處窄，不相識者，聽同床坐，不得眠。

Second, inquiring of the host and receiving a room, etc. The Vinaya states: One asks the resident bhikṣu, 'I have so many rains; is there a room allocated for me?' If he answers that there is, one should ask, 'Is anyone residing in it?' If there is no one, one should ask, 'Are there bedding, quilts, material requisites, utensils, room furnishings, and the like?' If there are, one should take them. Arriving at the room, having opened the door, one brings out the bed, mats, and the like, and sweeps the floor clean. If one finds a needle, thread, a small knife, or even a single medicinal pill, one should set it aside; if the owner recognizes it, one should give it to him. Having cleaned and swept the room in this manner, one then returns the bedding to its original place. One inquires where the latrine and urinal are, the clean ground, the unclean ground, the stūpa of the Buddha, the stūpas of the śrāvakas, the room of the first sthavira, down to the room of the fourth sthavira, and so forth, asking about each one separately; if the guest does not ask, the host should point them out and inform him one by one, even down to saying, 'This is a spittoon, this is a chamber pot,' and so forth. The Pañcavargika Vinaya states: If the dwelling place is cramped and the occupants do not know each other, they are permitted to sit on the same bed, but not to sleep [together on it].
