Know thyself.
–Socrates
The life according to reason is best and pleasantest, since reason more than anything else is man.
–Aristotle
The blessed and immortal nature knows no trouble itself nor cause trouble to any other, so that it is never constrained by anger or favor. For all such things exist only in the weak.
–Epicurus
Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well… The only real thing is, to study how to rid life of (the debilitating affects of) lamentation, and complaint, …and misfortune, and failure…For what else is tragedy, but the dramatized sufferings of men, bewildered by an admiration of the externals?
–Epictetus
What He said:
How blessed are the down and out! For of such of these is the Kingdom of God.
How blessed are those weeping! For they will be comforted.
How blessed are the humble! For they will inherit the Earth.
How blessed are the hungry and thirsty for salvation! For they will be fully satisfied.
How blessed are the merciful! For they will be given mercy.
How blessed are the pure-hearted! For they will behold God.
How blessed are those who pursue peace! For they will be called sons of God.
How blessed are those who pursue redemption! For of such of these is the Kingdom of God.
– Jesus
