But a religion that values experience as experience (and not as support for this or that theological position) can welcome transcendent experiences of all sorts. There are many well-trod paths that lead to direct experience of the divine: meditation, yoga, fasting, ritual magick, chanting, ecstatic dancing, and a host of others. The next religion will encourage these practices and will not be threatened by what comes of them.
Scientism might ask "Why bother?" but by now the answer should be readily apparent. Whether one believes that divinity is inside us or transcends us, it is the ultimate source of new moral vision and new values. Whatever happened to Moses on Sinai, Buddha beneath the bodhi tree, or Paul on the road to Damascus, it was not the result of rational, scientific reflection. And if it had been, it would not have changed the world.
