interesting on how the same thing can be used for different purposes:
Your use of the yi (intention) is to let go of all attachments and cultivate stillness through allowing change to happen, our method is to use the intention to actively bring together, balance and harmonize to create a dynamic neutral space (point of stillness). Many of us HAVE developed the cauldron through this method.
Seems to me that the term “stagnation” can be broadened to include stuckness at any level, form~energy~formlessness (or however you want to slice it up), and that different approaches apply to different levels (ex. physical work-out, energy work, deep-center stillness).
