4222. As regards the correspondence of the Grand Man with the things that appertain to man, it is a correspondence with all things of him both in general and in particular, that is to say, with his organs, members, and viscera, and this so perfect that there is not a single organ or member in the body, nor any part in an organ or member, nor even any particle of a part, with which there is not correspondence. It is well known that each organ and member in the body consists of parts, and of parts of parts-as the brain, for example, which consists in general of the cerebrum, cerebellum, medulla oblongata, and medulla spinalis, for this last is a continuation, or kind of appendix. Again, the cerebrum consists of many members, which are its parts, namely, of the membranes called the dura mater and pia mater, of the corpus callosum, the corpora striata, the ventricles and cavities, the smaller glands, the septa, in general of the cineritious substance and the medullary substance, and furthermore of the sinuses, blood vessels, and plexuses. The like is the case with the bodily organs of sense and motion, and with the viscera, as is well known from anatomical studies. All these things both in general and in particular correspond most exactly to the Grand Man, and to so many heavens, as it were, therein. For the heaven of the Lord is distinguished in like manner into lesser heavens, and these into heavens still less, and these into least, and finally into angels, each one of whom is a little heaven corresponding to the greatest. These heavens are most distinct from one another, each one belonging to its own general heaven, and the general heavens to the most general, or whole, which is the Grand Man.
