External control helps internal control in many ways. To succeed in external controls is more difficult than to achieve success in controlling the internal! A turn of the steering wheel in one's hand in any direction makes the wheels of the car, which are not in one's hand, move in the same direction. The wheels won't turn in one direction when the steering is turned in another; this is the natural. But sometimes, when the steering is turned one way, the wheels may drag another way, but this is due to the giving up of the natural characteristic. The internal wheels, if they have no air, which is the true essence, may behave as if there is no relationship with the steering. But they can't go beyond the bounds of steering; the steering in the hand is related to the wheels below. If there is no such relation, the journey becomes impossible. Therefore for the one who has struggled with and conquered the external tendencies, the internal tendencies become easily controllable.
