All wrong-doing arises because of mind. If mind is transformed can wrong-doing remain?

There is nothing so disobedient as an undisciplined mind, and there is nothing so obedient as a disciplined mind.

More than those who hate you, more than all your enemies, an undisciplined mind does greater harm.

Be devoted to conscientiousness. Guard your own mind.

The thing to do is to keep your mind when the world around you is losing theirs.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.
