“If there is in operation a constructive principle of Nature on the ethical, moral and spiritual planes of being, with which we must align ourselves and to which we must conform our conscious and voluntary activities in order to achieve self-completion, self-content, individual completion and happiness, then this constructive principle must be in operation also in our physical bodies and in their corelated physical, mental and emotional activities.  If the constructive principle is active in the physical as well as in the moral and spiritual realms, then the established harmonic relationship of the physical to the constructive law of its being must constitute the morality of the physical; and from this it follows that the achievement of health on the physical plane is as much under our conscious and voluntary control as the working out of our individual salvation on the higher planes of life.”

To recapitulate: 

First, our well-being on all planes and in all relationships of life depends upon the existence, recognition and practical application of the great fundamental laws and principles just explained.

Second:  Physical health, as well as moral health, is of our own making.  We are personally responsible not only for our own physical and mental health, but we are also morally responsible for the hereditary tendencies of our offspring toward health or disease.

Third:  The attainment of physical health through compliance with Nature’s laws is just as much a part of the Great Work as our ethical, moral and psychical development.

The Unity and Continuity of the Law

That which we call God, Nature, the Creator or the Universal Intelligence is the great central cause of all things and the vibratory activities produced by or proceeding from this central or primary cause continue through all spheres of life, in like manner as the light waves of the sun, moon and fixed stars penetrate through the intervening spheres of life to our plane of earth.  Therefore all powers, forces, laws and principles which manifest on our plane proceed and continue from the innermost Divine to the most external plane in physical nature.  This explains the continuity, stability and correspondence on all planes of being of that which we call Natural Law.  In other words, “Natural Law is the established harmonic relationship of effects and phenomena to their causes and of all particular causes to the one great primary cause of all things.”

Mental Therapeutics

The new psychology and the science of mental and spiritual healing teach us that the lower principles in Man stand or should stand under the dominion of the higher.  The physical body, with its material elements, is dominated and guided by the mind.  The mind is inspired through the inner consciousness, which is an attribute of the soul.  The soul of man is in communion with the Oversoul, which is the Source of all life and all intelligence animating the universe.
