Working with the Law presents Raymond Holliwell's systematic exposition of New Thought principles, emphasizing disciplined mental causation and conscious alignment with universal law. Holliwell argues that life operates according to fixed spiritual principles-laws of cause and effect, attraction, growth, and compensation-which function with the same reliability as physical laws. Rather than relying on vague optimism, he outlines a structured philosophy: clarity of thought, ordered intention, and sustained inner conviction are presented as the means by which individuals participate in the shaping of their experience. Written in the mid-twentieth century during the continued development of the New Thought movement, the book reflects a practical metaphysical framework rather than emotional exhortation. Holliwell's approach is methodical, positioning faith not as passive hope but as disciplined cooperation with principle. Working with the Law remains a representative document of prosperity philosophy in its classical form, offering insight into the intellectual lineage of later motivational and manifestation literature.
