Separation and Union of Yin Yang
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
A framework from the Suwen, the foundational text of Chinese medicine, describing the yin and yang channels through the paired ideas of separation and union. Each of the three yang and three yin channels is assigned one of three gate functions, opening, closing, or pivoting, with Taiyang as the opening, Yangming as the closing, and Shaoyang as the pivot. Separation means each divides into three; union means all three resolve back to a single yin or yang. The key qualification is that the two terms are complementary rather than opposed, describing a system that is simultaneously differentiated and unified.
SCAFFOLDING EFFECT
Reduce cognitive load
- Gate diagnosis: ask whether a problem is an opening failure, a closing failure, or a jammed pivot. - Fault localization: map symptoms onto specific gate functions before choosing an intervention. - Structural reading: hold division and unity together rather than treating the parts as separate systems.
Anchor fast decisions
A gated system stays stable only if each gate performs its assigned function at the right time. Opening admits, closing retains, and pivoting regulates the transition between them. When one gate fails, the failure propagates to the others, so a symptom appearing at one location often traces back to a gate that has stopped moving.
