9. Everything flows in with man in such a way that man is only an organ that receives. He is an organ receiving everything of heaven as to his mind, and he is a recipient of the world as to his body. Just as the eye is a recipient of light, the ears recipients of sound, and [so too] the remaining parts of the body, so the understanding is a recipient of the light of heaven, that is, of wisdom, and the will a recipient of the heat of heaven, and so of love. There is nothing else in man but the ability to receive; take the organs of the body to illustrate what that ability is like. Natural objects are perceived in the organs of the body as though they were present within them; and so too spiritual objects as if they were present within the mind, although they are not there. Fallacies arise from that sensation.
