Purely in an attempt to satisfy my own desire to understand what it is exactly you are saying, could I paraphrase your idea of neutrality being active as the well known concept of water finding it's way down a mountain stream?
Yes you could if you so wish for the water through neutrality, through little resistance, thus follows and flows according to the natural laws of nature.
Physically that is an analogy. Looking at a physical thing, water on a physical thing, a mountain.
Spiritually the rules are different. That is why trying to translate spirit or Ki in a physical manner leads to lots of people coming up with physical, logical sounding explanations, way off the mark.
