Myths and Symbols
Let us think of a living human being, with his tendency towards hardening on the one side and on the other, his tendency to hold something back. We see that these two tendencies separate when the human being reaches the age of seven—the time of the change of teeth. The tendency which culminates in ossification is manifest in the teeth. But the human being keeps back sufficient life-force to enable him to evolve. Up to the seventh year in the life of the human being it is only what belongs to the species, the genus, that can come to expression. At this point he is able to take his place in the cultural progress of the times and the school period begins. These two things are inwardly connected: the hardening tendency which comes to expression in the formation of the teeth and the tendency towards softening where something must be kept back, something that the etheric body—which becomes free at the seventh year—needs for its development. The two are connected.
