Is what you are referring to here part of what is often classified as internal part of the six harmonies?
The Three Internal Harmonies being:
Your spirit or "emotional mind" (xin) harmonises with your intention (yi)
Your intention harmonizes with your breath and physical momentum ("qi")
Your breath and physical momentum harmonise with your physical strength (li)
Since I have no background in the Chinese art i would hesitate to say that they mean exactly the same thing I am talking about but I would say that these principles are closely related. I didn't really get in to the aspect of how the breath relates to all of this.
