Spirit is the source and goal of all things; if matter did not have spirit in it, it would not awaken, it would not develop. Matter shows that life unfolds it, that life discovers it, that life realizes it: that consciousness which was so to speak buried in matter for thousands of years. By a gradual process it is realized through the vegetable and animal kingdoms, and in man it unfolds itself and takes its original condition. The only difference is that in this finishing of the spirit, this fulfillment of the spirit which manifests in man, there is variety: such a large number of human beings, millions and billions, and in their origin is one being.
