Here a typical example during education of children or adults as well. Now let's have a close look at the message you send them. Read the text by removing the negation and you read the affirmation of the message toward others that you are actually applying. Use positive affirmations in order to improve your health. I want to remain healthy, I want to become healthy.
Illness is a word of negative power.
By pronouncing it even in your mind, you increase the power, the energy of it within yourself. Instead use the opposite of illness. It is Divine and thus absolute powerful. Use health in a positive way and your being shall be a realization of that powerful energy. Health is Divine, as your true and innermost being is, so you may become a materialization of this Divine truth.
