Mortal mind is a term used in Christian Science to sum up all that would oppose God.
For success in spiritual healing, it’s important to understand that mortal mind possesses no power, influence or sway. It might look like it has power, at times, to the ignorant material senses, but it never does. Divine Mind is the only power.
When a patient expressed worry to me “that mortal mind was holding her down from making progress,” I replied, “Mortal mind can’t hold you down any more than a feather landing on your cap could weigh you down from walking across a room.”
She told me later that she got a hearty laugh out of picturing a feather on her cap trying to weigh her down and prevent her from moving ahead. The mesmerism broke.
God is the only power. There is no other. Understanding this truth enables us to love God more and fear mortal mind less, to the point of never fearing it!
“As named in Christian Science, animal magnetism or hypnotism is the specific term for error, or mortal mind. It is the false belief that mind is in matter, and is both evil and good; that evil is as real as good and more powerful. This belief has not one quality of Truth” Mary Baker Eddy, Science and Health, p. 103.
