Lecture III

The substance of the physical body is constantly changing; it is all the time being thrown off and replaced. Think only of your finger-nails and your hair. You cut your finger-nails and they grow again. But this is only a process that is externally perceptible; in reality, man is all the time throwing off matter and replacing it from within, from the inner centre of his being. Substance is perpetually scaling off and in seven or eight years time all the physical substance that was within us seven years previously has been thrown off and replaced by new. Just think of this.—Seven years ago I was able, to my great joy, to lecture to friends here in Breslau. There they were, sitting on chairs in front of me; but nothing remains to-day of the physical substance contained in those bodies; it has all vanished and been replaced by other physical substance. What has remained in each case is the individuality of spirit-and-soul. The individuality was present before birth, in pre-earthly existence, in earlier earthly lives too, and has remained. But the substance of the bodies sitting in the chairs seven years ago has long since passed away into other regions of the Universe. Now this exchange of substance begins at birth and is complete after the lapse of seven years or so. What our parents provide is the substance and its particular organisation up to the time of the change of teeth. Thereafter the task of moulding the substance is taken over by the individuality. The change of teeth is a process of great significance. Until that time we have received from our parents a model, this model resembles our parents, embodies the hereditary traits. Then, in accordance with this model, the individuality of spirit-and-soul slowly builds up the second body which exists from the time of the change of teeth to the onset of puberty, is then cast off, and the third body begins to develop. Hereditary traits which remain in us are due to the fact that in the second body we have copied them from the model. What is copied from the model at a later stage is adapted and elaborated by the unconscious faculty, acquired in pre-earthly existence, to mould the human organism in accordance with the secrets it contains. The purpose of the first body which we bear until the time of the change of teeth is to enable us, in conformity with our karma, to resemble our parents. The real secrets, the deep, all-embracing secrets whereby the human organism is built up as the wonderful image of the outer structure of the Heavens—these secrets in their innermost essence have to be acquired during the life between death and a new birth.
