A system of Denials and Affirmations is a part of the teachings of nearly all religious teachings.

From Lessons In Truth
by Emily Cady

Denial brings freedom from bondage, and happiness comes when we can effectually deny the power of anything to touch or to trouble us.

Repeat these four denials silently several times a day, not with a strained anxiety to get something out of them, but trying calmly to realize the meaning of the words spoken:

There is no evil.
There is no absence of life, substance or intelligence anywhere.
Pain, sickness, poverty, old age, and death cannot master me, for they are not real.
There is nothing in all the universe for me to fear, for greater is He (She) that is within me than he (she) that is within the world.

As it is with denials, so with the affirmations. There are four or five sweeping affirmations of Truth that cover a multitude of lesser ones, and which do marvelous work in bringing good to ourselves and to others:

Commit these to memory, so that you can repeat them in the silence of your own mind in any place and at any time. Strangely will they act to deliver you out of the greatest external distresses, places where no human help avails. It is as though the moment you assert empatically your oneness with God, there is instantly se into motion all the power of omnipotent love to rush to your rescue.
