Our picture of man is then as follows: in the larynx (iron) man develops the consciousness that reaches to the archetypes of the animal kingdom. It is the consciousness that belongs to the stars, but we are unaware of it in ordinary life. Higher still, in the region of the eyes (tin) is the consciousness of the archetypes of the plant kingdom and below are their reflected images. Crowning all is the centre of the lead consciousness which reaches to the Saturn sphere; our head centre is oblivious of the articles we write, they are the product of the heart centre. But the head is fully aware of the happenings in cosmic space. Our description of terrestrial events and activities proceeds from the heart; the head, meanwhile, can concentrate on the manner in which a divine being manifests himself in a pyrites, in a crystal of salt or of quartz.
