The Great Master expressed the ethical application of this law when he said:
"Give, and it shall be given unto you. . . . For with the same measure that ye mete it shall be measured to you again."—Luke 6:38.
In the realms of physical nature, giving and receiving, action and reaction balance each other mechanically and automatically. What we gain in power we lose in speed or volume, and vice versa. This makes it possible for the mechanic, the scientist and the astronomer to predict with mathematical precision for ages in advance the results of certain activities in Nature.
The great Law of Dual Effect forms the foundation of the healing sciences. It is related to and governs every phenomenon of health, disease and cure. When I formulated the fundamental Law of Cure in the words, "Every acute disease is the result of a healing effort of Nature," this was but another expression of the great Law of Action and Reaction. What we commonly call crisis, acute reaction or acute disease is in reality Nature's attempt to establish health.
Applied to the physical activity of the body, the Law of Com-pensation may be expressed as follows: "Every agent affecting the human organism produces two effects: a first, apparent, temporary effect, and a second, lasting effect. The secondary, lasting effect is always contrary to the primary, transient effect."
For instance: The first and temporary effect of cold water applied to the skin consists in sending the blood to the interior; but in order to compensate for the local depletion, Nature responds by sending greater quantities of blood back to the surface, resulting in increased warmth and better surface circulation.
The first effect of a hot bath is to draw the blood to the surface; but the secondary effect sends the blood back to the interior, leaving the surface bloodless and chilled.
Stimulants, as we shall see later on, produce their deceptive effects by burning up the reserve stores of vital energy in the organism. This is inevitably followed by weakness and exhaustion in exact proportion to the previous excitation.
The primary effect of relaxation and sleep is weakness, numbness and death-like stupor; the secondary effect, however, is an increase of vitality.
The Law of Dual Effect governs all drug action. The first, temporary, violent effect of poisonous drugs, when given in physiological doses, is usually due to Nature's efforts to overcome and eliminate these substances. The secondary, lasting effect is due to the retention of the drug poisons in the system and their action on the organism.
