b.) The next level of action is non-egoic action but action born out of an addiction to action. This is the action / movement that stems from the inability to simply sit.
c.) The most refined and highest level of action is that which is non-egoic and that which stems purely for the need of the action and not from an inability to sit silently. This is the level of saints!
In my opinion, enquiry and understanding are needed to transcend the first level. The more we understand why we do things to cater to the egos image, the more we will be liberated from it. The addiction to action requires first a genuine realization of the same followed by frequent periods where we sit down silently and observe the will to move. This is probably the best route to deaddict oneself from action and thereby transcend the second level.
Human society today has an extreme excess of the first level, scarcity at the second level and next to nothing at the third level. An inversion of this ratio would go a long way in establishing a just and non-violent society!
