Cast off your attachment to the past. There is beauty to be found in change.

Ten thousand flowers in spring, the moon in autumn. A cool breeze in summer, snow in winter. If your mind is not clouded by unnecessary things, this is the best season of your life. — a Chinese poem

This is a first principle of Buddhist psychology: See the inner nobility and beauty of all human beings.

A supple mind accepts change and is not attached to the past. Rather than lamenting change, it finds new beauty and hope in it. That is a life to which to aspire.
