"The human body is a collection of co-operative cells, more or less intelligent and responsive, therefore an important part of the thinking machine which is acted upon by the superior mind of the brain. The superior mind is in turn reacted upon by the automatic metabolism set up in the cells. Automatic metabolism of the cell, is its ability to carry on within itself the various processes of life that may be necessary to best fit it for the performance of special functions, as a particular part of the co-operative body. Violent emotions of anger, hate, despair and grief, are katabolic, poisonous and harmful; they tear down and destroy life. The poisonous deposits left in the cells by these emotions are called 'katastates.' Laughter and merriment, with all the emotions of pleasure, adoration, worship, love, affection, hope, beauty, etc., are 'anabolic,' or life-preserving. The vital, health-giving deposits left in the cells by these emotions are called 'anastates.' Nature accomplishes her perfect work by beautiful methods. The cells are fed and sustained by the circulation of the blood; they are reached from the smaller branching arteries by a network of minute, thread-like channels, sometimes called 'arterioles.' These arterioles are accompanied by the equally fine wires of the nervous system, closely connected with the brain centers. These wires are electrified by the emotions; they expand the arterioles, and the cells are flooded with an unusual supply of blood; thus they are correspondingly vitalized or poisoned, according to the kind of the dominant emotion, its duration and its intensity."
