Lovely painting, @harj in my own way of interpretation, I think the circles (Rings) represents Power/ Authority/Governments in cadre. The balls represents humans. In every sphere of our existence, we are never free. Watch closely there is some amount of freedom the balls have that is, they can roll to stretch out but at the end they are still held in the circle. Some balls escapes a certain ring but not two rings at a time, it tells us that some people are even bigger than a certain government at some point in time. In conclusion, someone’s master is another man’s slave.
