Everything changes! This is not a difficult thing to understand. As nature changes, so do we. A famous Buddhist phrase comes into my mind first: zhū háng wú cháng (諸行無常), which means "all things change." There is nothing that does not change. We exist through change. Life is a change. Our body cells are completely replaced every six years. We eat food and digest it through the process of metabolism. No change, no life.
To our dismay, our culture hardly accepts this very fact that we are to live with change. We often resist aging and dying, casting an unnecessary fantasy into life beyond this world. We don't need a utopia to escape this world.
How can we live a genuine life of a change without fears about the future? More than that, what would be an ideal character of transformation we love to embrace?
