Control your own mind, and you may never be controlled by the mind of another.

The mind is the most powerful weapon known to man. It simply cannot be controlled or contained by an outside force, however formidable that force may at first appear. Throughout history, tyrants have tried to control those who opposed them, but eventually these rulers discovered the power of the imagination was far greater than the threat of the sword. As Victor Hugo said, "An invasion of armies can be resisted, but not an idea whose time has come."
