I do not think we have any control except the control we are given. And the control we are given is a chance affair.
Our minds work in defined manners. We are floating on the stream of chaos. It is only the truth in us that keeps us afloat. We contain truths that cannot be annihilated. Truth is eternal. So is chaos. Truth is passive. Chaos active. Chaos initiates us but truth preserves us.
The only hope we have is that this chaos and this truth when they form us, that they bestow free will. That your wishes and intentions, and their fulfillment, are a part of it. This may be so.
There is no God but what there is, that void, that nothing, is the cause of your freedom absolutely and totally.
You are animated matter. Matter that behaves like a free individual. But if you looked too closed at yourself you would see the mechanism of neurons which create your every impulse and every thought or dream, They are very good artists.
Consciousness is a blank nothing, an absence of anything, until these neurons supply the content. You are death. Your body is death. But together life is made. Life is the ceremony, in the marriage of many totally chaotic elements.
