1.101

復有五事：一者不得無三法衣入眾僧坐、二者法衣不具不得入寺中止、三者至舍後未淨手不得著衣、四者至舍後未用水不得上塔、五者至舍後當脫袈裟僧迦支。

There are another five matters: first, do not sit in the Saṅgha without the three Dharma robes; second, if the Dharma robes are incomplete, do not dwell in a monastery; third, after going to the latrine, do not put on the robes until your hands are cleansed; fourth, after going to the latrine, do not ascend a stūpa before using water; fifth, when going to the latrine, take off the kāṣāya and the saṃkakṣikā.
