You have power over your mind - not outside events. Realize this, and you will find strength.

Observe the movements of the stars as if you were running their courses with them, and let your mind constantly dwell on the changes of the elements into each other. Such imaginings wash away the filth of life on the ground.

Thou sufferest justly: for thou choosest rather to become good to-morrow than to be good to-day.

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.

Does a man shrink from change? Why, what can come into being save by change?

Nowhere can man find a quieter or more untroubled retreat than in his own soul.
