[295] A bhikkhu arranging to share a sleeping place (sahaseyya) with one not fully ordained (anupasampanna) for more than two or three nights commits two offenses (āpatti): while in the act of lying down, there is an offense of wrong-doing (dukkaṭa); when he has lain down, there is an offense entailing expiation (pācittiya).
