Doctors keep their scalpels and other instruments handy, for emergencies. Keep your philosophy ready too - ready to understand heaven and earth. In everything you do, even the smallest thing, remember the chain that links them. Nothing earthly succeeds by ignoring heaven, nothing heavenly by ignoring earth.
Marcus AureliusThere is change in all things. You yourself are subject to continual change and some decay, and this is common to the entire universe.
Marcus Aurelius
