The brain is there for thinking and it is there for not thinking.
In modern humans, so it seems to me, thinking has crossed borders and it is operating in fields where it doesn't belong.
We just have to find out where thinking is justified and where not.
Thinking can just see things, compared to other things, but then the things are not unique anymore, they are seen through another, different thing.
"Your brain is not for thinking", sounds to authoritarian to me. Like we have to fight thinking, push it away, but that is a act of violence.
Only insight on how our brain is working, and what thinking is doing to us, allows us to raise our consciousness.
I hope that works for me one day.
