“体用”有三种不同含义：其一，形体、实体为“体”，形体、实体的功能、作用为“用”。其二，事物的本体为“体”，本体的显现、运用为“用”。其三，行事、行为的根本原则为“体”，根本原则的具体施用为“用”。在“体用”对待的关系中，“体”是基础，“用”是依赖于“体”的。Ti (体) and yong (用) can be understood in three different ways: 1) a physical thing and its functions or roles; 2) the ontological existence of a thing and its expression and application; and 3) the fundamental code of conduct, and its observance. In any ti–yong relationship, ti provides the basis on which yong depends.
显微无间。体用一源，至著者象也。至微者理也，
程颐︽程氏易传︾
◎ 最隐微的是理，最显著的是象。作为本体的理和作为现象的象出自同一来源，显著与隐微之间没有差别。
◎ What is most subtle is li (理), while what is most conspicuous is xiang (象). Li as the ontological existence and xiang as its manifestation are of the same origin; there is no difference between them. (Cheng Yi: Cheng Yi’s Commentary on The Book of Changes)
