What is it that makes man spiritual? Spirit-consciousness. If a person is not conscious of what he absorbs, he is not conscious of that which makes him more than the dense part of his being. It is not the dense substance which has formed his body that makes him capable of thinking, that gives him the faculty of feeling, of experiencing, of knowing; it is the spirit which this dense substance has absorbed. And if one asks whether this spirit which belongs to man, which may be called an individual spirit, is to be found within or without, the answer is that man himself is the individual spirit. The body is something which the spirit has taken for its use; therefore just as man is dependent upon this vehicle, which one calls the body, for experiencing the outer life, to the same extent or even more is he independent of the outer body in order to exist for ever.
