puberty is alien to the original dynamic flow. The new wave-length by no means corresponds. The new vibration by no means harmonizes. Force the two together, and you cause a terrible frictional excitement and jarring. It is this instinctive recognition of the different dynamic vibrations from different centers, in different modes, and in different directions of positive and negative, which lies at the base of savage taboo. After puberty, members of one family should be taboo to one another. There should be the most definite limits to the degree of contact. And mothers-in-law should be taboo to their daughters’ husbands, and fathers-in-law to their sons’ wives. We must again begin to learn the great laws of the first dynamic life-circuits. These laws we now make havoc of, and consequently we make havoc of our own soul, psyche, mind and health.
