The sacred waterfall of tahe Shuar people of Ecuador is breathtaking and beautiful. Yet standing before it, looking up into the rainbow that arches through the cascading waters, the visitor is struck by a feeling that transcends the magnificence of the landscape. No matter what your religion, you cannot help but sense the spirit of this place. Its power defies any attempt to describe the euphoria by a natural phenomenon so overwhelmingly grand that its voice seems to cross all the bridges of time.
I have learned to understand time and thought as a spiral: neither a straight line that must go always forward, even into a precipice, nor a circle that must remain forever stuck in repeating past experience. Instead, a spiral, which curves always backward in order to curve forward. What makes time and life into a spiral instead of a straight line or an endless circle is setting aside time for reflection, rest, renewal. That renewal time is the curve that moves the spiral onward. This lets us re-view where we have been, so that we can go forward.
