Mr. Walter left us with a set of courses and textbooks that can be applied through self-study, or by studying with a teacher. The courses start with the basic facts of Life, and teach the student how to reason and apply. The best way to begin is to engage a competent teacher to explain and direct your efforts to understanding. There is no set period of time that the courses take, and this really is a lifetime study.
To gain a practical understanding of the Science of Life, one must go about it in the same way that one would to gain a practical understanding of music or mathematics. The first requirement is books that deal plainly and correctly with the subject. Second: persistent self-application to the study of the books. Third: Through direct application, prove by right results obtained that one has grasped the understanding of the Science.
