What is the Three Breathes theory (三氣) ?

[Goaforce]

Hello everyone. 

 

There exists in the Daoist tradition a theory named the Three Breathes theory (三氣) according to which the creation of all things proceed from three breaths, the mystery (玄), the origin (元) and the principle/beginning (始), which can also be found in the human being on the ontological and physical levels. 

I am looking for a detailed explanation of this theory, and would like to understand what are mystery, origin and principle, which are respectively symbolized by the black, white and yellow color.

Can someone help ?

Thank you very much.

Sounds a bit like in Nei Dan litterature, when you merge Nature and Life (Xing and Ming) with the help of the yellow matchmaker. 

 

Wang Mu Foundations of internal alchemy might be helpful as a start, although most of these books tend to obscure the subject.
