Mortal mind counterfeits the real consciousness. Every conclusion or inference it predicates is dependent upon the perceptions of the physical senses. These conclusions, having no other basis than the testimony of the material senses, are not susceptible of proof and must therefore be classified as unreal because untrue. On page 9 of "Unity of Good" Mrs. Eddy writes: "Material and sensual consciousness are mortal. Hence they must, some time and in some way, be reckoned unreal."
Christian Science teaches that as there is only one God, one infinite Mind, there can be but one consciousness. The real consciousness knows only truth; and all that is true can be traced to its source in this consciousness. The omnipotent Mind is the permanent dwelling place of the real man of God's creation, hence we can only behold the image and likeness of God in consciousness.
Through the understanding of God, or spiritual discernment, man reflects the divine consciousness. This spiritualization of consciousness not only clears the vision as to the allness of God, the only cause and Principle of being, but reveals man to be the perfect manifestation or embodiment of Spirit, not of matter. Through a logical process of reasoning it becomes clear that the transient, mortal concept of man as matter has nothing to support its claim to a place in this purely spiritual creation. The real consciousness must invalidate all false impressions that have no permanency or Principle in the realm of the real. When every doubt on this point is destroyed, it will be seen that not only mortal mind, counterfeiting the divine Mind, but the mortal body, the phenomenon of this so-called mind, is also a false presentment of the real man. On page 409 of Science and Health Mrs. Eddy writes, "mortal mind and body combine as one." This combination having no foundation to rest upon, its evanescent, fictitious testimony consists in certain human beliefs having no claim to causality, from which the inevitable conclusion is reached that they have no reality in fact.
