“In its physiological prayerful state, noetic energy moves cyclically like an axle turning within the heart. In its ailing state, noetic energy does not turn like an axle cyclically, but while being rooted in the heart, it unfolds and cleaves to the brain and creates a short-circuit between the brain and the heart. So, the concepts of the brain that are all from the environment become concepts of noetic energy always rooted in the heart. So, the sufferer becomes a slave of his environment … The undefeatable weapon against the devil is the healing of this short circuit between the heart’s noetic energy and the brain’s reason. The healing consists of the limitation of all concepts in the brain, whether they be good or bad, which is achieved only when the noetic energy of the heart returns to its physiological cyclical movement by means of unceasing noetic prayer. Those who maintain that it is possible to cast out bad concepts and keep only good ones in the brain are naïve. One must know the concepts of the devil with precision to defeat him. This is achieved by means of the cyclical movement of prayer in the heart … noetic prayer. “
