There is nothing else on Earth so wonderful to watch

Rudolf Steiner:  "If one looks quite simply, with ordinary consciousness, at the wonders revealed in the progressive development of the human being from the first days of his life, we can at least gain some idea, some feeling, of the tremendous depths out of which the soul and spirit struggle during those first days and weeks in order to give an increasingly definite form to much that in the infant is still formless; and then gradually to bring under control the chaotic movements of arms and legs. We come to feel that we are being shown how a spiritual activity, present in the endless depths of the hidden life of nature, is expressing itself in the human body. And we can say: There is nothing else on Earth so wonderful to watch as the unfolding of the inner human being within the outer, during the development of a child in the very first years of its life. If we know how to watch this with true artistic-religious insight, then all that can be seen there, and the humility we can feel in face of this revelation of the spiritual, surpass all other artistic, scientific, or religious impressions that can be received from the outer world."
