It is a connection on two planes, the upper and lower.

From the lower sympathetic center the profound intake of love or vibration from the living co-respondent outside.

From the upper sympathetic center the outgoing of devotion and the passionate vibration of _given_ love, given attention.

The two sympathetic centers are always, or should always be, counterbalanced by their corresponding voluntary centers.
From the great voluntary ganglion of the lower plane, the child is self-willed, independent, and masterful.
In the activity of this center a boy refuses to be kissed and pawed about, maintaining his proud independence like a little wild animal.
From this center he likes to command and to receive obedience.

From this center likewise he may be destructive and defiant and reckless, determined to have his own way at any cost.
From this center, too, he learns to use his legs.
