Does religion produce unique sensations?

[Nope]

There is only one thing I have seen faith in a deity able to produce that I have not encountered a secular institution capable of doing, and that is ecstasy. I'm not talking about Hitler making people go wild flailing at his rally, I mean genuine absolute conviction, contentment and occasionally even non-stop orgasmic bliss such as the experience several mystics like Teresa of Avila experienced.

I suspect this is because no secular institution has ever made as grandiose a claim as Christianity, so there is a far less tempting reward on offer for most Communists to devout themselves so fully. Even still the works and speeches of the likes of Julian of Norwich, John of the Cross and the two Fatima seers who died as kids are of something I have never seen elsewhere. Could be just hot-house environments leading to their productions, I have noted mystics do not appear outside of convents, monasteries or ultra devout locales but I've never seen a school or a philosophical academy produce something like that.

When I was religious, I experienced a feeling that could be described as ecstasy during prayer. No hallucinations like mystics experience but a definite high just the same. The human mind is amazing. If I had lived in the Middle Ages I might have been a mystic. My guess is that intense prayer is like meditation or maybe a form of mild self hypnosis

It would be interesting to learn how to turn such an experience on and off. Sometimes I get a similar experience when I am outside looking at very beautiful scenery.
