“All things change; nothing perishes.”
“Omnia mutantur, nihil interit (everything changes, nothing perishes).”
“Let nothing perturb you, nothing frighten you. All things pass. God does not change. Patience achieves everything.”
“If you realize that all things change, there is nothing you will try to hold on to. If you are not afraid of dying, there is nothing you cannot achieve.”
“Visible objects therefore do not perish utterly, since nature repairs one thing from another and allows nothing to be born without the aid of another's death.”
“If nothing ever changed, there would be no such things as butterflies.”
