Liu explained: "Tranquillity is not the same as silence. The sound of the birds, cicadas, of pines swaying and bamboo creaking in the wind, of rain falling on the roof, of men calling in the mountains, or a bell sounding in the night, these can all give a feeling of tranquillity.
「寧靜並不是無聲」，劉墉說，「蟬鳴、鳥囀、竹韻、松濤、潺潺的流水、點滴的簷雨，乃至空山人語、夜半鐘聲，都能給予人寧靜的感受。
