The Christian Scientist's constant prayer is to rise above the generally accepted beliefs which compose what Mrs. Eddy has called mortal mind, the fictitious, temporal mind of which she writes in Science and Health (p. 400), "Mortal mind rules all that is mortal."
That which is mortal is that which is believed to be destined to die. Hence mortal mind is simply a term of reference for a mentality receptive to the belief that matter exists in and of itself and is therefore sentient and intelligent; that it is the source of life of all creatures from the amoeba to man himself. Such a theory would disavow and disclaim the great primal fact of one all-embracing creator, God.
There is nothing more heartening than to be assured, as we are in Christian Science, that to understand God as the only Life is to be freed from the mortal belief which asserts that because matter is real, death is unavoidable. To rise above the belief in the inevitability of death through step-by-step demonstration of divine Mind's dominion over what is called matter is to rise above the suffering which belief in matter's reality brings to the human experience.
