This slim paperback originally published in 1950 was apparently designed to clarify the Spiritual Mind Treatment for practitioners. Additional to the guidance designed to hone their skill, it offered insight into some rather interesting departures by this philosophy from the New Thought movement originating over a hundred years ago--e.g., "The subjective reactions of the individual are a result of personal experience, plus the collective experience, plus the impact of the universal Mind upon the consciousness of everything (p.80)."
It's a keeper on my shelf for the clearly defined tenets that are part of each Treatment Example; I am looking forward to reading Living the Science of Mind, also by Holmes.
