Parent love is established at the great primary centers, where man is father and child, playmate and brother, but where he _cannot_ be comrade or lover.

Comrade and lover, this is the dynamic activity of the further centers, the second four centers.

And these second four centers must be active in the parent, their intense circuit established even if not fulfilled, long before the child is born.

The circuit of friendship, of personal companionship, of sexual love must needs be established before the child is begotten, or at least before it attains to adolescence.

These circuits of the extended field are already fully established in the parent before the centers of correspondence in the child are even formed.
