Our mortal mind develops beliefs within us that attract illness and poverty into our lives. Cady says that our real self is "never sick, never afraid, never selfish." When Dr. Cady first published the articles now known as "Lessons In Truth" in Unity Magazine, she acknowledged that studies at that time had proven that error beliefs—beliefs engendered by the mortal mind—could by persistent effort change the conditions in our bodies and our experiences. In the last 120 years, this has been proven time and again, not just by official studies, but by the demonstrations of thousands upon thousands of people.
In the method suggested by Cady, we should first deny that the erroneous thought and/or feeling has any power to make us unhappy. Second, we should deny that these things exist at all in reality. Consequently, following this train of thought, you can see that denial in this context simply means proclaiming that something is not true.
"The appearances are that our bodies and our circumstances control our thoughts, but the opposite is true. Our thoughts control our bodies and our circumstances." This is the truth that supports the action of denial. If it is our thoughts that determine our experiences, then the only variable affecting our manifestations is what is determining the ideas we accept as true. Are we looking to the world, using our mortal mind, to determine what is possible for us or are we looking to Divine Mind, God, as the Source of all substance? The choice we make here is crucial.
Cady indicates that there are four powerful denials that will take away power from erroneous thoughts that create much suffering in our worlds.
1) There is no evil.
2) There is no absence of life, substance, or intelligence anywhere.
3) Pain, sickness, poverty, old age, and death cannot master me, for they are not real.
4) There is nothing in all the universe for me to fear, for greater is He that is within me than he that is in the world.
In declaring these statements, do not do it with a sense of desperation, for fear is a creation of mortal mind. "Denial brings freedom from bondage, and happiness comes when we can effectually deny the power of anything to touch or to trouble us," says Cady.
Remember: the practice of denial is about recognizing the falsity of a thought or feeling and being willing to declare this in your life. Your persistent effort is akin to drawing the shadows of these erroneous thoughts out into the light.
