飯上有十事，左右顧視無不有罪：一者當視上座受案未；二者當視上座前具未；三者視下座亦爾；四者人皆飯，當復視之，上座前少，何等有盡者為呼益；五者視下座亦爾；六者飯未已，當復中止視，上座欲得何等；七者視下座亦爾；八者當視上座已未，設自先已，以手持前所有，不得坐視人；九者視下座亦爾；十者不得先取案，當排之、當持待人。

During meals there are ten matters where looking left and right is without offense: first, one should look to see whether the sthavira has received the table or not; second, one should look to see whether the utensils in front of the sthavira are ready or not; third, looking at the junior monks is also like this; fourth, when everyone is eating, one should look again, and if there is little before the sthavira or anything has run out, call for more to be added for him; fifth, looking at the junior monks is also like this; sixth, before the meal is finished, one should stop midway and look again to see what the sthavira wishes to have; seventh, looking at the junior monks is also like this; eighth, one should look to see whether the sthavira is finished or not, and if oneself has finished first, hold what is before oneself with the hands and not sit looking at people; ninth, looking at the junior monks is also like this; tenth, one must not take the table first, but should push it aside and hold it waiting for others.
