The difficulty must have come from distrust and disobedience. For distrust and disobedience are like falsehood (they are themselves a falsity, based on false ideas and impulses), they interfere in the action of the Power, prevent it from being felt or from working fully and diminish the force of the Protection. Not only in your inward concentration, but in your outward acts and movements you must take the right attitude. If you do that and put everything under the Mother’s guidance, you will find that difficulties begin to diminish or are much more easily got over and things become steadily smoother.
In your work and acts you must do the same as in your concentration. Open to the Mother, put them under her guidance, call in the peace, the supporting Power, the protection and, in order that they may work, reject all wrong influences that might come in their way by creating wrong,careless or unconscious movements. Follow this principle and your whole being will become one, under one rule, in the peace and sheltering Power and Light.
