#introspection

Talk to yourself once in a day, otherwise you may miss meeting an intelligent person in this world.

No man ever prayed heartily without learning something.

When the mind is concentrated and turned backward on itself, all within us that is stubborn will have to give way.

A man does not gaze into running water to see his face; he gazes into still water.

Thinking is the talking of the soul with itself.

The unexamined life is not worth living.

Look well into thyself; there is a source of strength which will always spring up if thou wilt always look.

Silence is a lesson learned from the many sorrows of life.
