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

Everything that happens happens as it should, and if you observe carefully, you will find this to be so.

You are a little soul carrying about a corpse, as Epictetus used to say.

If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.

Such as are your habitual thoughts, such also will be the character of your mind; for the soul is dyed by the thoughts

Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.
