You are repeating yourself unnecessarily. I know what you mean. I simply don’t think it’s relevant. Not only that, but you’re also overshadowing reality by doing so.
A cup is filled with water. It is in a state of being full of water. When you empty it from water, it changes its state to a state of being empty of water. Indeed, we go so far as to say that the cup is completely empty, containing no substance within itself.
This is true but not in the literal sense. If we took a closer look, we could see that there is still something within it e.g. air molecules. Though that is true, it is irrelevant to us. The point is that there is less substance in it (tenuity) than before (density.)
There is no absolute vacuum. In fact, there is no absolute anything.
None of that changes the fact that for all practical purposes the cup is empty.
The same is with nervous system.
Think of nervous system as a kind of plate that can be filled with nervous activity.
When this plate is completely filled with nervous activity, one is maximally motivated. When it is empty, one is at rest (perhaps unconscious.) When its capacity is exceeded, one is overwhelmed.
The brain has the capacity to control the degree of motivation (e.g. how filled, or activated, one’s nervous system is.) You can increase or decrease motivation.
Rest, or not doing, is an absence of nervous activity. Remember, there is no absolute vacuum, so even if there is no nervous energy in one’s nervous system, there is still something in there. But more importantly, it is rare for a man to achieve a state of total absence of nervous activity within one’s nervous system (in the same way that one can achieve a state of total absence of water, or other dense substance, within a cup.) Instead, rest is often associated with a range of lower degrees of nervous activity.
Resting, being a process, refers to a decrease in nervous activity.
Doing qua state refers to a range of higher degrees of nervous activity.
Doing qua process refers to an increase in nervous activity.
You are basically denying all of this by reducing the reality of self-direction to mere “change of orientation”.
