凡住持上堂。小參普說入室。並擊之。擊鼓之法上堂時三通（先輕敲鼓磉二下。然後重千徐徐擊之。使其緊慢相參。輕重相應。音聲和暢。起復連環隱隱轟轟　若春雷之震螫。第一通延聲長擊。少歇轉第二通。連聲稍促更不歇聲。就轉第三通一向纏聲擊之侯。住持登座畢方歇聲。雙椎連打三下）小參一通。普說五下。入室三下皆當緩擊。

Whenever the abbot ascends the hall, gives small gatherings, gives general sermons, or conducts private instruction in the abbot's room, it is struck. The method of beating the drum: when ascending the hall, three rounds (first lightly tap the drum rim twice, then beat with heavy strokes slowly, making tight and slow alternate, light and heavy correspond, the sound flowing smoothly, rising and returning in an unbroken ring, rumbling and thundering like the stirring of insects by spring thunder. The first round prolongs the sound with long beats, pauses slightly, and shifts to the second round, which accelerates somewhat in unbroken sound without pausing; it then shifts immediately to the third round, beating throughout in an uninterrupted continuous sound; only after the abbot has completely mounted the seat does the sound cease, with the double mallets striking three times in rapid succession). For small gatherings, one round; for general sermons, five strikes; for private instruction in the abbot's room, three strikes; all should be struck slowly.
