Think of the universe and what a small part of it thou art

Think of the universal substance, of which thou hast a very small portion; and of universal time, of which a short and indivisible interval has been assigned to thee; and of that which is fixed by destiny, and how small a part of it thou art.  Marcus Aurelius.  Meditations.  Book 5.
