9. The Course of Human Development from the Standpoint of Spiritual Science
But with this birth, only the one link, the physical body, is born. Now there is a second and a third birth for man. When man is born, he is still surrounded by an invisible etheric and astral covering. Just as this covering is pushed back in the womb and at birth, so too is the etheric covering pushed back when the teeth change and the etheric body is fully born. This is the second birth. It takes place slowly and accompanies the time when the milk teeth are replaced by other teeth. When a person has left his etheric body, he is still surrounded by the astral body. The third birth occurs at puberty. Then the astral cover is pushed back and the person becomes receptive to astral influences. These are important moments that must be taken into account. The first seven years: the first epoch. The second epoch – from seven to fourteen years – is essentially different, and so is the third, from fourteen to twenty-one years. Then the human being develops his astral body in a free way through the I that lies behind it.
