3.210

三千威儀經云不得大欬（謦妙）咤（咤字去聲嘆也）噴（噴嚏）㖑（㖑許介切喝也）歎息思念世事。不得倚壁。欲起以時。若意走不定。當自責。即起經行。

The Sūtra of Three Thousand Dignified Manners states: 'One must not cough loudly (qing-he), click the tongue (zha is in the falling tone, meaning to sigh), sneeze, yawn (he, pronounced xu-jie, means to open the mouth wide), sigh, or think about worldly affairs. One must not lean against the wall. One should rise at the proper time. If the mind wanders unsettled, one should reproach oneself and immediately rise to practice walking meditation.'
