“Acquaint thyself with God.”

“Know thyself, and thou shalt know the universe and God.”

“Know thyself and thou shall know all the mysteries of the gods and the universe.”

“Know thyself, presume not God to scan;The proper study of mankind is man.”

“If we wished to gain contentment, we might try such rules as these: 1. Allow thyself to complain of nothing, not even of the weather. 2. Never picture thyself to thyself under any circumstances in which thou art not. 3. Never compare thine own lot with that of another. 4. Never allow thyself to dwell on the wish that this or that had been, or were, otherwise than it was, or is. God Almighty loves thee better and more wisely than thou dost thyself. 5. Never dwell on the morrow. Remember that it is God's, not thine. The heaviest part of sorrow often is to look forward to it. "The Lord will provide.”

“Know thyself,’ said Socrates.Know thyself,’ said Sappho, ‘and make sure that the Church never finds out.”
