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.

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.

Walnuts have a shell, and they have a kernel. Religions are the same. They have an essence, but then they have a protective coating. This is not the only way to put it. But it's my way. So the kernels are the same. However, the shells are different.

At the center of the religious life is a peculiar kind of joy, the prospect of a happy ending that blossoms from necessarily painful ordeals, the promise of human difficulties embraced and overcome.

The word translated, koan, it means a problem. But it's a very special problem. And to strip it down to the way it works, you are given a problem which has no rational solution. There is a contradiction built into it. One standard - one is this is the sound of two hands clapping. What is the sound of one hand clapping? And so on. All right, so the first thing is that it brings your rational mind to an impasse.

In India there was a sense of time that does not tick with modern clocks, just as there is a knowledge that is not gained through science and empirical experiments. In the modern West knowledge is of objective, finite particulars in historical time. India recognizes that kind of useful information: it calls it "lower knowledge." Higher knowledge (paravidya) proceeds differently, or rather it doesn't proceed at all but enters history full-blown on the morning of a new creation.

...yesterday and today and tomorrow are not an arrow that shoots from past to present to future; rather all tenses, and sleeping and waking, mix and cohabit in an atemporal duration beyond clocks and calendars. The Aboriginal world began long ago when the Ancestors sang in Dreamtime the cosmic rhythms that give shape to the things we see, and it is the beginning right now, when a living Tiwi sings the Dream songs that continue, or are, the world.
