大比丘三千威儀 1.43

1.43

經行有五事：一者當於閑處、二者當於戶前、三者當於講堂前、四者當於塔下、五者當於閣下。

In caṅkramaṇa, there are five matters: first, it should be in a quiet place; second, it should be in front of the door; third, it should be in front of the lecture hall; fourth, it should be beneath the stūpa; fifth, it should be beneath the upper gallery.
