That the case is thus, few can believe, because men do not know what the spiritual is, and what the natural, and still less how these are distinguished from each other; also what correspondence is, and what influx; and that the spiritual, when it flows into the organic forms of the body, presents living operations such as appear; and that without such influx and correspondence not even the most minute particle of the body can have life and be moved. As to these things I have been informed by living experience that not only heaven in general flows in, but also the societies in particular; likewise what the societies are and of what quality which flow into this and that organ of the body, and into this and that member; and further, that there is not one society only which flows into each organ or member, but very many, and that in each society also there are very many; for the more there are, so much the better and stronger is the correspondence, inasmuch as perfection and strength are from the unanimous multitude of many who act as a one in a heavenly form; hence results a more perfect and stronger endeavor into particulars according to the numbers.
