4803. A matter wholly unknown in the world and worthy of mention is this: The states in which good spirits and angels live undergo constant change and perfection. In this way they are conveyed to the more internal parts of the province in which they dwell, and so into more excellent functions. For in heaven purification takes place constantly, which is so to speak a new creation. Yet the situation is that no angel to all eternity can possibly attain complete perfection. The Lord alone is the perfect One, He being the root and the source of all perfection. Those who correspond to the mouth constantly wish to be speaking, for speaking gives them utmost pleasure. While undergoing perfection they are restricted to speaking nothing but that which is beneficial to companions, the community, heaven, and the Lord. The delight they take in speaking in that way grows in the measure that the desire to regard themselves in what they speak and to strive after wisdom from what is properly their own passes away from them.

377. I am about to discuss the correspondence of the heart and the lungs with volition and discernment. Upon this rests the correspondence of everything in the body, called the members of the body as a whole, the sensory organs, and the body's viscera. Further, the correspondence of physical things with spiritual ones has not been recognized even though it was fully demonstrated in two works, one of which is Heaven and Hell and the other of which is on the spiritual meaning of the Word in Genesis and Exodus, titled Secrets of Heaven. For all these reasons, I should like now to point out the sections of these two works where I have written explanations of correspondence.

In Heaven and Hell, there is material on the correspondence of everything in heaven with everything in us, 87-102; and on the correspondence of everything in heaven with everything on earth, 103-115.

In the work on the spiritual meaning of the Word in Genesis and Exodus, titled Secrets of Heaven, there is material on the correspondence of the face and its expressions with the feelings of the mind: 1568, 2988, 2989, 3631, 4796, 4797, 4880 [4800], 5195 [5165], 5168, 5695, 9306;

on the correspondence of the body in its motions and actions with matters of discernment and volition: 2988, 3632, 4215;

on the correspondence of the senses in general: 4318-4330;

on the correspondence of the eyes and their sight: 4403-4420;

on the correspondence of the nostrils and smell: 4624-4634;

on the correspondence of the ears and hearing: 4652-4634 [4652-4659];

on the correspondence of the tongue and taste: 4791-4805;

on the correspondence of the hands, arms, legs, and feet: 4931-4953;

on the correspondence of the groin and the reproductive organs: 5050-5062;

on the correspondence of the inner viscera of the body, particularly the stomach, thymus, the cisterna, the chyle and its ducts and the mesentery: 5171-5180, 5189 [5181];

on the correspondence of the spleen: 9698;

on the correspondence of the peritoneum, kidneys, and bladder: 5377-5396 [5377-5391];

on the correspondence of the liver and the ducts of the liver, of the bladder, and of the pancreas: 5183-5185;

on the correspondence of the intestines: 5392-5395, 5379;

on the correspondence of the bones: 5560-5564;

on the correspondence of the skin: 5552-5573;

on the correspondence of heaven with a person: 911, 1900, 1982 [2162], 2996, 2998, 3624-3649, 3741-3745, 3884, 4091 [4041], 4279 [4280], 4423 [4323], 4524, 4525, 6013, 6057, 9279, 9632;

on the fact that everything in the physical world and its three kingdoms corresponds to something you can see in the spiritual world: 1632, 1881, 2758, 2890-2893 [2990-2993], 2897-3043 [2987-3003], 3213-3227, 3483, 3624-3649, 4044, 4053, 4156, 4366 [4936], 4939, 5116, 5377, 5428, 4477 [5477], 8211, 9280; that everything you see in heaven is a correspondence: 1521, 1532, 1619-1625, 1807, 1808, 1971, 1974, 1977, 1980, 1981, 2299, 2601, 3213-3226, 3348, 3350, 3457 [3475], 3485, 3748 [3747], 9481, 9570, 9576, 9577. The correspondence of the literal meaning of the Word with its spiritual meaning is dealt with throughout, and is also treated in Teachings for the New Jerusalem on Sacred Scripture 5-26, 27-69.

6057. Before anything can be said about the influx and operation of the soul into the body, a proper knowledge is required of the truth that the internal man has been created so as to conform to an image of heaven, and the external man to an image of the world, so much so that the internal man is the smallest form heaven can take, and the external man is the smallest the world can take and is thus the microcosm. The fact that the external man is an image of the world can be seen from his external or physical senses. The ear has been made to conform to the whole nature of the modification of air, and the lungs to the whole nature of air-pressure. So too with the surface-areas of the body, which are held in shape by the pressure of air all around them. The eye has been made to conform to the whole nature of the ether and light; the tongue to the perception of particles dissolved and suspended in fluids, and at the same time along with the lungs, trachea, larynx, glottis, jaws, and lips to conform to the power of using air in varying ways to produce articulated sounds or words, and musical sounds too. The nostrils have been made to conform to the perception of particles suspended in the atmosphere, and touch, a sense which is distributed over the whole of the body, to the perception of changes in the condition of the air, that is to say, whether it is cold or hot, as well as the perception of the nature of fluids and the weights of objects. (The internal organs, which the air surrounding the body cannot enter, are held together and kept in shape by a purer kind of air, called ether.) This is not to mention all the deeply hidden aspects of the natural world that have been inscribed on and apply themselves to the body, such as all the secrets of mechanics, physics, chemistry, and optics. All this goes to prove that the entire natural order was drawn on so that the external side of the human being might be created in conformity with it, which was why the ancients named the human being the microcosm.

[2] Now just as the external man has been created so as to conform to an image of everything in the world, so the internal man has been created so as to conform to an image of everything in heaven, that is, an image of the celestial and spiritual qualities that come from the Lord, from which heaven is formed and in which it consists. The celestial qualities there are all the aspects of love to the Lord and charity towards the neighbour, and the spiritual qualities are all the aspects of faith. They are intrinsically so great and of such a nature that no tongue can possibly declare even a millionth of them. The truth that the internal man has been made so as to conform to an image of all those qualities is plain to see in the angels. When they appear before a person's internal sight, as they have appeared before mine, their presence alone stirs feelings to the depths of his being. For love to the Lord and charity towards the neighbour pour out of them and into the onlooker; and what is radiated by that love and charity, namely rays of faith, shines out of them and stirs one's affections. This has served to show, as well as other proofs, that because the internal man has been created to be an angel, the internal man is the smallest form heaven can take.

[3] From all this it now becomes clear that within the human being the spiritual world has been joined to the natural world. As a result, in the case of the human being, the spiritual world flows into the natural world in so vital a way that a person can discern it if he merely stops to pay attention to it. This also shows what the interaction of the soul with the body is, that strictly speaking it is a communication of the spiritual realities of heaven with the natural things of the world, a communication which is effected by one flowing into the other, yet depends on the way the two have been joined together. This communication effected through an inflowing which depends on the way the two have been joined together is unknown at the present day, for the reason that every single thing is attributed to natural forces and there is no knowledge of what is spiritual, which at the present day is so remote that when people give it any thought it seems to be non-existent.
