If you want to get back your faith and keep it, you must first quiet your mind and make it open and obedient to the Mother’s Force. If you have an excited mind at the mercy of every influence and impulse, you will remain a field of conflicting and contrary forces and cannot progress. You will begin to listen to your own ignorance instead of the Mother’s knowledge and your faith will naturally disappear and you will get into a wrong condition and a wrong attitude.
