Water is patient; it can stagnate and let itself be coated with scum if need be. It is as gentle as the morning's dew. It is non-confrontational, even respectful, in circumventing the rocks in a stream. It makes room for everything that enters its pools. It accommodates by assuming the shape of any vessel it is poured into. And it is humble, seeking always the lowest level. Yet along with - or rather because of these adaptive, yielding properties, it is ultimately irresistible; it carves canyons out of stone.

As the twentieth century began, science equaled a materialistic worldview. As the twenty-first century began, the worldview of science, at least of physics and astronomy, may have traded place with that of religion. Consider Einstein's famous equation E = mc2. Nothing of matter dies but continues on in another form, elsewhere. The church divines and theologians for two thousand years have devised arguments and "proofs" of immortality but nothing equal to this.

I don't want to justify religion in terms of its benefits to us. I believe that, on balance, it does a lot of bad things, too - a tremendous amount. But I don't think that the final justification of religion is the good it does for people. I think the final justification is that it's true, and truth takes priority over consequences. Religion helps us deal with what is most important to the human spirit: values, meaning, purpose, and quality.

I grew up taking it for granted that missionaries were what American boys grew up to be.

A religion made up solely of heightened religious experiences would not be a religion at all. ...The major religious traditions address the mysteries (with or without entheogens), but they have other business to do: widen understanding, give meaning, provide solace, promote loving-kindness, and connect human being to human being.

Ancient wisdom and quantum physicists make unlikely bedfellows: In quantum mechanics the observer determines (or even brings into being) what is observed, and so, too, for the Tiwis, who dissolve the distinction between themselves and the cosmos. In quantum physics, subatomic particles influence each other from a distance, and this tallies with the aboriginal view, in which people, animals, rocks, and trees all weave together in the same interwoven fabric.

I've spent the last 50 years or so steeping myself in the world's religions, and I've done my homework. I've gone to each of the world's eight great religions and sought out the most profound scholars I could find, and I've apprenticed myself to them and actually practiced each faith.
