If atoms of life can have so marked an influence upon a man nearly forty years of age, _i.e._, at a period when he is in full possession of himself, how much more powerful is this influence when exercised upon the child--a delicate, sensitive body, almost entirely lacking the control of the soul? This is the reason hired nurses often transmit to the child their own physical features and countless moral tendencies which last some time after weaning; orphans, too, morally, often resemble the strangers who have brought them up. Like physical tendencies these moral propensities disappear only by degrees, according to change of environment, and especially to the degree in which the body is controlled by the reincarnated soul.[73] The most important, however, of the moral influences at work on the being again brought into touch with earth-life is connected with the emotions, the passions and thoughts of those around. The child--and under this name must be included the embryo and the foetus--possesses bodies the subtle elements of which are in a dormant state; his mental and sense organisms are scarcely more than masses of substance that have not yet been vitalised--a sort of collection of germs of good or of evil, which will yield fruit when they awake. The passional and mental vibrations of the parents play on the matter capable of responding to them in the invisible bodies of the child; they vivify it, attract atoms of the same nature taken from the finer atmosphere around, and awake in it passional and mental centres which, but for them, might have remained latent, or, at all events, would only have developed at a later stage, when the Ego, master of its vehicles, would be in a position to struggle against the outer evil influences and not permit them to have effect save within the limits imposed by will. In this way, it is possible to bring to birth evil instincts in a child, and intensify them to a considerable extent, before a single virtue has succeeded in expressing itself on the new instrument in course of development. This mental action is so strong that it colours vividly, if not altogether, the morality of the little ones living beneath its influence, and even older children are still so sensitive to it that whole classes are seen to reflect the moral character of the teacher who has charge of them. This influence, too, does not cease with childhood, it weighs--though far less heavily--on the man during the whole of his life; and families, nations, nay, even races, each see through the prism of their own special atmosphere. Mighty and subtle is this illusion which man, in the course of his pilgrimage towards divine Unity, must succeed in piercing and finally entirely dissipating.
