There are people who decide to put their lives in service of religion, whether secular or monastic. As a result of taking up these responsibilities, they receive the approval of the religious community and the belief that God is also happy with them. As they carry out their religious role and responsibility, they also have engaged certain chemical functions in the brain called the dopamine reward cycle.
So the result of religion is a steady drip of dopamine which provides a sense of well being. Like any addict, the person will defend their religious practices to the death; maybe not even knowing that they are defending an addiction, not anything that really has to do with God.
Wait a second! What did I just say? "...not anything that has to do with God?"
Yep, either God is every where and equally FOR everyone no matter what, or God is a selfish angry bastard which I want nothing to do with. All religions think they are special to god. The bible describes the angry version of god. I studied the bible in various venues from Roman Catholic Seminary to atheist publications to scholars in Ivy League universities. I no longer believe it is 100% true or sacred. While beautiful and containing wisdom, there are plenty of other documents which are beautiful too.
It is very difficult to leave a belief system because you lose the dopamine reward it was providing. To do without the approval and the dopamine is very frightening and depressing. But, to think different thoughts than the main stream of people, you have to step out of the stream. It is difficult to dare to be different. It is difficult to brave the disapproval of the group.
If there is one monastic practice I've kept strongly, it is renunciation of the world. But I live here, so I renounce by taking myself out of the mainstream. There are numerous ways to not-go-along with the group. When you add them up, it produces a different out look on life. To have different thoughts, you have to get away from the main stream thoughts.period.
I don't want my life to be one dopamine reward cycle after another. I don't want my God to be a function of dopamine. In not-going-along, I lose my dopamine rewards. So happiness and life satisfaction has to come some other way. God has to have some other basis for being.
I do study some spiritual material, but it is not an evangelical matter. I can't even explain it here. The text has to be studied and digested. It's thesis is not at all what is taught to most people.
