nightowl You've said it all there. I think most religions have a place for meditation and I suspect it is the act of meditating and its effect on brain waves that gives a "spiritual high"! However one interprets that "high" probably depends on your culture or your particular belief system.
Banning it is horribly dogmatic.
If my musings above are right then all religious beliefs can give this sense of peace, fullfillment, religious ecstasty or whatever you want to call it! If that effect makes people feel well happy, calm and loving why does it matter how people get it.
This is beginning to sounds like the drug MDMA (ectasy. )
