"Think this about the fleeting world: a star at dawn, a bubble in the stream."These falls have been here for many, many years, and yet bubbles on the stream come and go in an instant. So is it permanent, or is it fleeting? Think of it this way:
"One man watches a river flow by. If he does not wish it to flow, to change ceaselessly in accord with its nature, he will suffer great pain. Another man understands that the nature of the river is to change constantly, regardless of his likes and dislikes, and therefore he does not suffer. To know existence as this flow, empty of lasting pleasure, void of self, is to find that which is stable and free of suffering, to find true peace in the world."
