When therefore the four great centers of the extended consciousness arouses in a child, at adolescence, they must needs seek a strange complement, a foreign conjunction.
Not only is this the case, but the actual dynamic impulse of the new life which rouses at 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.
