Pretty much agreed. A calm unworried soul is not particularly interested in the questions religion is positioned to answer. A contradiction pretty directly addressed by a strand of eastern christian mysticism (and others). Where many historical saints were illiterate and essentially ignorant of the fundamentals of their own religion, and this is considered good and correct: they naturally follow god's will and so have no need to learn about it any other way.

And then you get into theory vs practice I guess without a useful distinction either way. The pali canon might be chill, but devout buddhists have still done genocide. The archetypal tolstoyan pious serf might be chill but the russian orthodox church certainly never has been.
