Yin-Yang
Definition:
A foundational theory of universal law in Chinese philosophy, Yin-Yang expresses the fundamental distinctions that permeate all existence. It recognizes that everything is distinct—not only in relation to other things but also within itself—and is constantly shifting from moment to moment.
These distinctions are symbolized by the contrast between Yin, often associated with softness, passivity, or smallness, and Yang, linked with strength, activity, or largeness.
This general framework is also applied in Taijiquan: upward movement is generally categorized as Yang, and downward movement as Yin, and so on.
Usage:
- As a noun: “In Taijiquan, Yin-Yang defines forward movement as Yang and backward movement as Yin.”
Additional Notes:
In Taijiquan, Yin-Yang manifests as the coexistence of two opposing yet interdependent states throughout movement. This interplay operates on three levels: physical motion, muscular activity, and intention （Yi）. Forward movement is generally Yang, while backward movement is Yin; muscle tightening is Yang, while Relaxation （or the reduction of tension） is Yin—and mental intentions follow the same relational pattern.
