A good disposition is invincible, if it be genuine.
It is in your power to withdraw yourself whenever you desire. Perfect tranquility within consists in the good ordering of the mind, the realm of your own.
Nothing befalls a man except what is in his nature to endure.
The universe is transformation: life is opinion.
Everything that exists is in a manner the seed of that which will be.
Remember: Matter: how tiny your share of it. Time: how brief and fleeting your allotment of it. Fate: how small a role you play in it.
