369. It is acknowledged, indeed, that man is such as his reigning love is, but only in respect to his mind and disposition, not in respect to his body, thus not wholly. But it has been made known to me by much experience in the spiritual world, that man from head to foot, that is, from things primary in the head to the outmosts in the body, is such as his love is. For all in the spiritual world are forms of their own love; the angels forms of heavenly love, the devils of hellish love; the devils deformed in face and body, but the angels beautiful in face and body. Moreover, when their love is assailed their faces are changed, and if much assailed they wholly disappear. This is peculiar to that world, and so happens because their bodies make one with their minds. The reason is evident from what has been said above, that all things of the body are derivatives, that is, are things woven together by means of fibers out of first principles, which are receptacles of love and wisdom. Howsoever these first principles may be, their derivatives cannot be different; therefore wherever first principles go their derivatives follow, and cannot be separated. For this reason he who raises his mind to the Lord is wholly raised up to Him, and he who casts his mind down to hell is wholly cast down thither; consequently the whole man, in conformity to his life's love, comes either into heaven or into hell. That man's mind is a man because God is a Man, and that the body is the mind's external, which feels and acts, and that they are thus one and not two, is a matter of angelic wisdom. 370. It is to be observed that the very forms of man's members, organs, and viscera, as regards the structure itself, are from fibers that arise out of their first principles in the brains; but these become fixed by means of such substances and matters as are in earths, and from earths in air and in ether. This is effected by means of the blood. Consequently, in order that all parts of the body may be maintained in their formation and rendered permanent in their functions, man requires to be nourished by material food, and to be continually renewed. 371. THERE IS A CORRESPONDENCE OF THE WILL WITH THE HEART, AND OF THE UNDERSTANDING WITH THE LUNGS. This shall be shown in the following series: (1) All things of the mind have relation to the will and understanding, and all things of the body to the heart and lungs. (2) There is a correspondence of the will and understanding with the heart and lungs, consequently a correspondence of all things of the mind with all things of the body. (3) The will corresponds to the heart. (4) The understanding corresponds to the lungs. (5) By means of this correspondence many arcana relating to the will and understanding, thus also to love and wisdom, may be disclosed. (6) Man's mind is his spirit, and the spirit is the man, while the body is the external by means of which the mind or spirit feels and acts in its world.
