It’s not impermanence per se, or even knowing we’re going to die, that is the cause of our suffering, Rather, it’s our resistance to the fundamental uncertainty of our situation. Our discomfort arises from all of our efforts to put ground under our feet, to realize our dream of constant okayness. When we resist change, it’s called suffering.
As human beings we share a tendency to scramble for certainty whenever we realize that everything around us is in flux. In difficult times the stress of trying to find solid ground—something predictable and safe to stand on—seems to intensify. But in truth, the very nature of our existence is forever in flux. Everything keeps changing, whether we’re aware of it or not.
