“Change is the very nature of Nature. if there's one thing that doesn't change, it is the fact that everything changes. In the Korean tradition of Tao, this is called impermanence. The teaching about impermanence can be summarized like this: Anything that has a beginning must have an end. Anything that is created will change. Impermanence is the very nature of things. Realizing that nothing is permanent is the true beginning of enlightenment. Suffering comes from attachment that wants to hold something permanently that is not permanent in its intrinsic nature. Awakening to the truth of impermanence frees you from attachment.”
