The tendency to be worried over nothing, to become anxious about little things, to be fidgety and restless, to be afraid, to be confused, the tendency of moving about without any reason, the tendency of speaking without purpose, the tendency of being sad without any motive, all these things come through lack of control over the mind. Have they also any other effect besides the effect that is made upon one's own personality? Yes; all weaknesses, errors, and mistakes that man makes against his own wish, all these come from lack of control over his own mind. And if there is a secret of success the key to it is the control of mind. Intuition, inspiration, revelation, all come when the mind is controlled. And all worries, anxieties, fears, and doubts come from lack of control.
