大比丘三千威儀 2.89

2.89

復有五事：一者不得倚左右人肩、二者不得妄起至上座前邊坐、三者不得妄咄叱摩波利若下坐、四者不得解袈裟著上座舍出、五者不得坐自搖使床有聲。

There are further five matters: first, one must not lean on the shoulders of the persons to one's left or right; second, one must not rise without cause and sit next to the sthavira; third, one must not scold or snap at the vihārapāla or junior monks without cause; fourth, one must not unfasten the kāṣāya, leave it at the sthavira's quarters, and go out; fifth, one must not sway while sitting, making the bed creak.
