From a letter dated 1897
Remember, that the power to heal is gained through peace, wisdom, love, dominion over ourselves, and good will toward men. You possess these graces of Spirit, or Christ power, only by loving God, good, supremely. After this, cometh the recognition of but one Mind, which enables you to know there is no power or presence that can resist good, or can prevent your prayers being effectual. While you remain in this attitude of mind you are obedient to the Principle of your being, and naught can hinder your healing the sick and the sinner.
