THE EVOLUTION OF MAN IN THE OTHER WORLD
Know that nothing which exists remains in a state of repose, that is to say, all things are in motion. Everything is either growing or declining, all things are either coming from non-existence into being, or going from existence into non-existence. So this flower, this hyacinth, during a certain period of time was coming from the world of non-existence into being, and now it is going from being into non-existence. This state of motion is said to be essential -- that is, natural; it cannot be separated from beings because it is their essential requirement, as it is the essential requirement of fire to burn. (330:2)
