Christian Healing: the science of being, by Charles Fillmore, [1926], at sacred-texts.com

These are not simply lectures; they are, rather, lessons. They are not merely to be read; they are to be studied and applied as one studies and applies mathematical rules.

When the text suggests that the reader "hold a thought," or affirm or deny a certain proposition, the student should stop reading, and both audibly and mentally do as bidden. This will set up new thought currents in mind and body, and will make way for the spiritual illumination that will follow in all who are faithful to these instructions.

The statements following each lesson should be used for mental discipline. Write these statements down and apply them daily while studying the lesson to which they correspond. Anyone can do spiritual healing who will use the simple rules of denial and affirmation here set forth. If you wish to heal another, hold him in mind and mentally repeat the denials and affirmations; this will raise your consciousness to spiritual reality, where all healing power originates. If you wish to heal yourself, talk to your mind and body as you would talk to a patient.
