Thus the mixture of positive and negative forces shape everything from the atom to our character and health. If we desire a warm temperature we have to balance hot and cold. In order to feel healthy we might have to either add or subtract a vitamin, mineral or amino-acid. Most important is the precise knowledge of what is missing or unbalanced.
