I've always been scientifically-minded. What's changed is that I've realized the absurdity of trying to cram Eastern (or Western, for that matter) supernaturalism into a scientific worldview.
For example, when I was a devotee of an India-based spiritual group, Radha Soami Satsang Beas, I wrote a book for RSSB called "Life is Fair." It set forth a karmic justification for vegetarianism.
Much of the book talked about the positive health effects of being a vegetarian rather than a meat eater. But some of the book discussed karmic theory in which causes and effects carry over from one life to another via reincarnation.
Discarding that unproven speculative stuff leaves us with determinism.
Causes produce effects, which produce more causes, in an unbroken chain of causes and effects that goes all the way back to the Big Bang some 14 billion years ago. So nothing valuable was lost when I gave up a belief in the supernatural side of karma.
Because I'm left with determinism, the aspect of karmic theory that makes sense.
Likewise, I used to have faith in God, a guru who was God in human form, soul, spirit, life after death, and journeying through higher supernatural realms of creation.
I enjoyed believing in these entities, even though there was zero demonstrable evidence that any of them actually existed. I had faith that one day all would be revealed to me through copious meditation, adhering to certain ethical vows enjoined by Radha Soami Satsang Beas, and the grace of the Guru/God.
Now I've come to realize that faith is foolish.
People have faith in all sorts of mutually incompatible things. Christians have faith in God, Muslims in Allah. Members of opposing football teams each have faith that a divinity is on their side. Religious adherents have faith that their own peculiar rituals and theologies will lead to eternal salvation.
I much prefer hope in my current churchless frame of mind.
Hope is faith shorn of supernaturalism. Hope recognizes that almost always in everyday life the future can't be predicted with 100% accuracy. Yes, determinism rules. But often, if not usually, life is so complex some form of chaos theory comes into play, where small causes can have big effects.
Or, known causes can have unknown effects.
Either way, hope springs eternal, as the saying goes. Even when things look really dismal, and no way out seems apparent, there's the possibility of something unexpected happening.
Being found when you're lost in a wilderness. Recovering after a dismal diagnosis. Feeling better even though depression seems like it will be with you forever. Finding a true love after many years of loneliness.
Hope is realistic. Faith isn't. Just as determinism is, and karmic theory isn't.
