In a flower…
In a flower, there are two constituents: one that is constantly changing — the body part, the form. And then, hidden behind the form, the formless, which is unchanging.
Flowers come and go, but their beauty remains. Sometimes it is manifested in a form, sometimes it dissolves back into the formless. Again there will be flowers, and beauty will assert itself. Then the flowers will fade, and the beauty will move into the unmanifest. And the same is happening with human beings, with birds, with animals, with everything.
Always remember that you are not the momentary, but the eternal; not the changing, but the unchanging.
