Creatures..........................

32.  Many of the anxieties that harass you are superfluous:  being but creatures of your own fancy, you can rid yourself of them and expand into an ampler region, letting your thought sweep over the entire universe, contemplating the illimitable tracts of eternity, marking the swiftness of change in each created thing, and contrasting the brief span between birth and dissolution with the endless aeons that precede the one and the infinity that follows the other.


-Marcus Aurelius,  Meditations,  Book IX
