荀子所提出的一種用以把握日用倫常之道的心靈狀態(tài)。荀子認(rèn)為，需要通過心的作用才能知“道”。但人心時常處于被遮蔽的狀態(tài)，只有進(jìn)入“虛壹而靜”的狀態(tài)才能發(fā)揮應(yīng)有的作用?！疤摗笔遣皇挂咽詹卦谛闹械闹R妨礙將要接受的東西?！耙肌笔鞘雇瑫r兼得的知識類目分明，彼此無礙?！办o”是不以虛妄而混亂的知識妨礙正常的心靈活動。

This refers to a state of mind Xunzi proposed as a way to master the Dao of general morality. He believed that one gets to know Dao through the action of one's heart and mind. But since the human heart and mind are often closed, they can only function normally when one is open-minded, concentrated, and consequently tranquil. Xu (虛), or open-mindedness, prevents prior knowledge from hindering the acquisition of new knowledge. Yi (壹), or concentration, allows one to assimilate knowledge of different categories while keeping them from interfering with each other. Jing (靜), or tranquillity, is to keep the false and confusing knowledge from obstructing one's normal process of contemplation.
