Leave other people's mistakes where they lie.

The soul becomes dyed with the color of its thoughts.

A man's happiness,-to do the things proper to man.

Your time has a limit set to it. Use it, then, to advance your enlightenment; or it will be gone, and never in your power again.

When men are inhuman, take care not to feel towards them as they do towards other humans.

Because your own strength is unequal to the task, do not assume that it is beyond the powers of man; but if anything is within the powers and province of man, believe that it is within your own compass also.

It is the duty of men to love even those who injure them.
