Israel Regardie published books with the Law of Attraction theme as one of his prevailing Universal Laws. In, The Art of True Healing: A Treatise on the Mechanism of Prayer and the Operation of the Law of Attraction in Nature (1937), he taught a focused meditation technique to help the mind to learn to heal itself on a physical and spiritual level. Regardie claimed that the Law of Attraction was a valid method for attracting good physical health and for improvement in any aspect of one's life.

He then regained his health and recovered, an event that prompted his study of "mind over body". Although he never used the words 'Law of Attraction', he explained this in a statement that captured the concept in the field of health:
And, just as an important side note: Your subconscious is way, way more powerful than you possibly give it credit for. Most people don’t realize this fact. Your subconscious knows exactly what you’re going to do. It’s infinitely more aware of what’s happening in the universe than your conscious mind. It simply won’t be bullied. It’s happy for you to tell it what to do, once you master the process of doing so.
