Artistic, and widely read, Donald contributed to alternative magazines and created anti-war and save-the-whale designs, which he produced on T-shirts. He rejected organized religion becoming interested instead in the kind of religious experiences described by mystics through the ages and more contemporary writers such as Aldous Huxley and Timothy Leary. He immersed himself in esoteric Tibetan Buddhist writings, and became a Rosicrucian for a while, interests remarkably similar to Isabel’s.

Using his graphics arts skills, Donald redrew the dowsing charts and teaching diagrams which Isabel used in her work with patients, and in the seminars she gave. By 1999 Donald was an established desktop publisher, and Isabel asked him to produce her writings for publication.
