3624. THE CORRESPONDENCE WITH THE GRAND MAN, WHICH IS HEAVEN, OF ALL THE ORGANS AND LIMBS, BOTH INTERIOR AND EXTERIOR, OF THE HUMAN BEING
Let me now tell of and describe marvels which, so far as I know, have not as yet been known to anyone, nor has even the idea of them entered anyone's head - the marvel that the whole of heaven has been formed in such a way that it corresponds to the Lord, to His Divine Human; also the marvel that the human being has been formed in such a way that every single part of him corresponds to heaven, and through heaven to the Lord. This is a great mystery which is now to be revealed, it being the subject here and at the ends of chapters that follow this.

Nor do acts take shape in the mind exactly as they present themselves through actions in the body; rather, it is thoughts that are configured there. Things that belong to the mind are spiritual while those that belong to the body are natural. From this it is evident that a correspondence exists between spiritual things and natural, and that there is a representation of spiritual things within natural. Or what amounts to the same, when the things that belong to the internal man take shape in the external, the things which are visible in the external are representative of the internal, and those in the external which accord with those in the internal are correspondent.
