From the Lecture: Mystery of the Human Temperaments
"Let us, for instance, take the choleric person, who has a strong firm center in his inner being. If the ego predominates, the person will assert himself against all outer oppositions; he wants to be in evidence. This ego is the restrainer. Those pictures are consciousness-pictures. The physical body is formed according to its etheric body, the etheric body according to its astral body... Choleric persons appear as a rule as if growth had been retarded. [short] Thereby he reveals clearly that the other members of his being have been held back by the excess of ego. Not the astral body with its forming capacity is the predominant member, but the ego rules, the restrainer, the limiter of the formative forces. Hence we see as a rule in those who are preeminently men of strong will, where the ego restrains the free formative force of the astral body, a small compact figure. Take another classical example of the choleric: Napoleon, the “little General,” who remained so small because the ego held back the other members of his being. There you have the type of the retarded growth of the choleric. There you can see how this force of the ego works out of the spirit, so that the innermost being is manifest in the outer form.
