Religious and so-called spiritual people use uniquely person methods of
controlling their moods and perceptions. They may pray for guidance or sit in meditation or any other number of methods. Either way they seek a certain satisfaction in life and they have found a reliable means of delivering it to themselves.

Religious life in no way validates religious perceptions or beliefs, but it does make up a working-model.

From these people and their practices, we can poach.

Great explanations do not make for a rich life. As humans we are fated to play out a very limited set of human possibilities. However, within this limited set we can find satisfaction. Our freedom lies in embracing the human model with all its limits.

The brain is intimately connected to the body and to our outside environment via the body. So it does not ever exist by itself (unless removed from a deceased person). So when we speak of the brain, we don't mean a brain in a jar, but instead a brain fully clothed with receptors intimately linked to the body, its sense and organs and the surrounding environment.

Still, without the brain there is no typical perception. So however limited we are by language and no matter how reliable our understanding is of our universe, we are still locked into a completely human brain. We are brain-centric. And the brain
is a complex web which can never be unravelled. The course of our understanding will never be complete.

When one is heartsick a scientific explanation will give you no peace, but a loving gesture may.- Witgenstein
