Mātikāvibhaṅga

Vinayapiṭaka · Bhikkhu Vibhaṅga (2) · Vol. 2 · Section 26

[26] A dwelling (vihāra) belongs to a single family and is enclosed: having deposited the robe within the dwelling, one must stay within the dwelling. It is unenclosed: one must stay in that dwelling in which the robe has been deposited, or one must not go beyond arm's reach (hatthapāsa). A dwelling belongs to different families and is enclosed: one must stay in that dwelling in which the robe has been deposited, or at the base of the door, or one must not go beyond arm's reach. It is unenclosed: one must stay in that dwelling in which the robe has been deposited, or one must not go beyond arm's reach.
