Clear and calm mind is not deadly as you claim. Its just calm and it stresses only when there is a reason when survival is threatened as it is wired to do so. Read my post on the brain and anxiety if you wish. Especially anxiety disorders and emotional proceasing.All i am saying is that we should all learn to be calmer and enjoy our lives more not worrying too much about the future or dwell in the past even though worrying about the future help us to prepare our selves for danger. Our brains become anxious to protect from threats and this is how evolution shaped us. All i am saying is that our brains should be calmer and worry only about objective immediate threats and when there is real danger not worrying for the sake of worrying. That consciousness is an absurdity and an accident of nature together with the whole universe seems to fall in the realm of philosophy mostly and as much as you debate it using scientific evidence it wont get you far.
