Lecture VI

The solid parts have only been built into this human form gradually. There were originally no bones in the human body, even when it had already descended. The bones were developed from soft cartilaginous structures which traversed the human body like cords. These in their turn originated from quite soft substances, and these soft substances from fluid substances, these from airy, the airy from etheric and the etheric from astral which had densified from spiritual substantiality. If you trace it back you will find that everything material has originated from the spiritual. Everything is in archetype in the spiritual world. It was only the Atlantean epoch that the bones, formerly merely indicated, actually developed in man.
