Do you find any difficulty in healing? If so, strive for the higher sense of the nothingness of matter, namely, the allness of God. Do not care to search into causation, for there is no cause or effect in matter. All is Mind, perfect and eternal. Whenever you treat a patient, include in your understanding of the case, that no ignorant or malicious mind can affect the case, then there is no relapse. Science tells us this in all it manifests.
Progress is the law of the infinite, and finite views are but the suppositions and beliefs. Now, realize this and be a law to every case. When you commence treating, know there is but one Mind, and this one governs your patient. There are no minds to interfere; error is not mind and has no power over you or your patient.
These are the rules for you to work out every hour of your life. Realize constantly that no malicious mind can affect you, or make you believe you cannot cure your patient. Begin this way. Mary Baker Eddy (Carpenter, Gilbert, Essays On Christian Science, p.51)
