Perfection

I would guess that we all have some concept of perfection.  For some maybe it's a view of a physical form, like a spoon, its sense of being just right, feeling just right, looking just right.  Maybe it's the functional value of that object - it gets the job done. Perfect and there you have it.  For some it might be a perception of one's action, or that action within the context of a response, like doing something, the feeling of doing it or the sense of having someone else acknowledge what you're doing.  For some there might be some moral aspect, perfection in the overall goodness of an action or the outcome of an action.  For some it might be something about naturalness, a feeling that something is just as it should be.  For some it might just be a feeling of relief, that you can finally rest, breathe in and relax knowing that you've done the best you can, have gotten as realistically close to perfection as you can ever possibly get, so that's that, enjoy. 

A hand moves along a surface.  An eye moves along a surface.  Breath moves along a surface.  Maybe the surface itself is moving, seeing, breathing back.
