I am curious about how theists and former theists intensity of spirituality is/was compared to the average person. While it is impossible to peer into the lived experiences of others I do think we are capable of making some educated guesses.
For me, I was very spiritual since I was 3 or 4. Coincidently a time period where the human brain starts to develop a sense of theory of mind (empathy). The spirituality was a constant onslaught. Sometimes the feelings were so intense they hurt. Suffering was the main framework. Out of the monks and nuns I investigate, the more intense ones are those who seem to also incorporate a sense of suffering into their spiritual framework.
This was when I was not even making any real effort into meditation. It was not until my last few years as a theist that I started to practice mediation and escalating the spiritual feelings to be as strong as possible. Ironically enough, it was also during this time that I slowly started to look at my spirituality through a secular lens. I even started slipping the idea into my thoughts and speech that the spirituality I was feeling were just emotions. A convergence of spirituality and secularity was somewhat molding together.
Unfortunately I soon lost my faith, and was suddenly and violently ripped away from my spiritual feelings. I dealt with what I personally described as severe chemical withdrawals for a few years. Even now ten years later my brain is not the same and life almost feels permanently gray and lifeless.
I am interested in hearing about other people's experiences. This being CF, I suspect a more spiritually intense crowd than the average population. I am also curious about hearing stories from other former theists about experiencing some of the negative effects from losing their faith that I did.
