We know that all is impermanent; we know that everything wears out. Although we can buy this truth intellectually, emotionally we have a deep-rooted aversion to it. We want permanence; we expect permanence. Our natural tendency is to seek security; we believe we can find it. We experience impermanence at the everyday level as frustration. We use our daily activity as a shield against the fundamental ambiguity of our situation, expending tremendous energy trying to ward off impermanence and death. We don’t like it that our bodies change shape. We don’t like it that we age. We are afraid of wrinkles and sagging skin. We use health products as if we actually believe that OUR skin, OUR hair, OUR eyes and teeth, might somehow miraculously escape the truth of impermanence.
The Buddhist teachings aspire to set us free from this limited way of relating. They encourage us to relax gradually and wholeheartedly into the ordinary and obvious truth of change. Acknowledging this truth doesn’t mean that we’re looking on the dark side. What it means is that we begin to understand that we’re not the only one who can’t keep it all together. We no longer believe that there are people who have managed to avoid uncertainty.
