Every instant of time is a pinprick of eternity. All things are petty, easily changed, and vanishing away. — Marcus Aurelius. Roman emperor from 161 to 180
In the life of a man, his time is but a moment...his sense, a dim rushlight. All that is body is as coursing waters...all that is of the soul, as dreams, and vapors.
I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinion of himself than on the opinion of others.
Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe love nothing so much as to change. The Universe is change.
