26. It is an arcanum in heaven and in the world, namely that from creation, every good conjoined with truth clothes itself in forms, chiefly the human form, since Divine Good and Divine Truth proceed from the Divine Human of the Lord, and from every part of his Body. The putting on of form which is everywhere in the atmospheres, is an arcanum which no one yet knows, and it is an essential of the spiritual, as well as of the natural atmosphere. Hence it is that insects are born, each one whatever it is according to its spiritual genius, and so it is that affection everywhere clothes itself with a body. Hence there are so many insects, large and small. That the same is true of the vegetable kingdom is because their prime substances are in Nature and thus are devoid of life, etc., etc., and that they have reference to the human, etc., etc.
