This section is from the "Nature Cure: Philosophy and Practice Based on the Unity of Disease and Cure" book, by Henry Lindlahr.
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."
