6056. It has just been said that being prior the internal man can remain in being without the external, but not the external man, being posterior, without the internal. For it is a universal law that nothing can remain in being by itself, only from and through another, consequently that nothing can be maintained within the form it possesses except from and through another, as every single thing in the natural order goes to prove. The same is true of the human being. So far as his external man is concerned, he cannot remain in being except from and through the internal. But the internal man cannot remain in being except from and through heaven; nor yet can heaven do so from itself, only from and through the Lord, who alone is Self-existent. What makes all coming into and remaining in being is influx, for influx is the means by which all things are kept in being. But it will be shown in a later section that through influx the Lord keeps every single thing in being, not only indirectly through the spiritual world but also directly both in intermediate causes and in ultimate effects.
