Pactum serva" - "Keep the faith

Ut haec ipsa qui non sentiat deorum vim habere is nihil omnino sensurus esse videatur."

If any man cannot feel the power of God when he looks upon the stars, then I doubt whether he is capable of any feeling at all.

Pulvis et umbra sumus. (We are but dust and shadow.)

Non est ad astra mollis e terris via" - "There is no easy way from the earth to the stars

Fas est ab hoste doceri.
One should learn even from one's enemies.

A man leaves his great house because he's bored
With life at home, and suddenly returns,
Finding himself no happier abroad.
He rushes off to his villa driving like mad,
You'ld think he's going to a house on fire,
And yawns before he's put his foot inside,
Or falls asleep and seeks oblivion,
Or even rushes back to town again.
So each man flies from himself (vain hope, because
It clings to him the more closely against his will)
And hates himself because he is sick in mind
And does not know the cause of his disease.
