When the mind is not active one is unaware of its existence--for instance, when attention is wandering or in deep sleep. A study of physiology shows that eye, nerve, and brain must combine to tell a person that he sees something and even then he does not see it until the mind pays attention to it. The truth is that the mind creates its own objects--but not the individual, finite mind; only the Mind which is back of it and which is infinite and common to all individuals. This is difficult to understand, so to make it easier one has to think of dream. In that state he can see cities, men, women, and children, mountains and flowers, hear voices, feel pain, and so forth. What is more, everything is so real then that at the time it is the waking state to him, not dream. Now who created all these scenes and things? Not his finite mind, for he is not conscious of having done so. Hence there is a larger mind within him which has this power of manufacturing scenes, objects, and events so vividly that he takes them to be real. This reality is a myth or, as the Indians call it, Maya.
Mrs. Eddy came extremely close to grasping this point and indeed of all the Western cults Christian Science stands closest to the ultimate teaching. Unfortunately it has mixed much error with truth and is ignorant of other vital teachings which are needed to complete the circle of knowledge. This impurity is due to the ego--the selfish, grasping personality which Mrs. Eddy possessed and which prevented her full initiation. The ego must be utterly yielded if one wants truth.
All this implies that matter is also a myth, unreal. Still more it implies that the ego is a myth, illusory. Here, then, is the first practice of the ultimate path: think constantly of that Mind which is producing the ego, all the other egos around, and all the world, in fact. Keep this up until it becomes habitual. The consequence is that one tends in time to regard his own ego with complete detachment, as though he were regarding somebody else. Furthermore, it forces him to take the standpoint of the all, and to see unity as fundamental being.
Those who have shown the worst features of hate, selfishness brutality, and separateness, are as much productions of this infinite Mind as others--only they have concentrated their full attention on the ego, and they have clouded reason by passion, while submitting to the stronger mental forces which propaganda has hypnotically let loose upon them.
