Marcus Aurelius: “Let then the reason itself not trouble itself.”

If then there is an invincible necessity, why dost thou resist?

That which is from fortune is not separated from nature or without an interweaving and involution with the things which are ordered by providence.

Begin the morning by saying to thyself, I shall meet with the busybody, the ungrateful, arrogant, deceitful, envious, unsocial.

In the application of thy principles thou must be like the pancratiast, not like the gladiator; for the gladiator lets fall the sword which he uses and is killed; but the other always has his hand, and needs to do nothing else than use it.
