It is our attitude toward events, not events themselves, which we can control. Nothing is by its own nature calamitous -- even death is terrible only if we fear it.

There is but one way to tranquility of mind and happiness, and that is to account no external things thine own, but to commit all to God.

Man is not fully free unless he is master of himself.

No man is disturbed by things, but by his opinion about things.

What is it that every man seeks? To be secure, to be happy, to do what he pleases without restraint and without compulsion.

Does a man reproach thee for being proud or ill-natured, envious or conceited, ignorant or detracting? Consider with thyself whether his reproaches are true. If they are not, consider that thou art not the person whom he reproaches, but that he reviles an imaginary being, and perhaps loves what thou really art, though he hates what thou appearest to be.

There is nothing good or evil save in the will.
