294. Because those things that constitute the sun of the spiritual world are from the Lord, but are not the Lord, they are not life in itself, but are devoid of life in itself; just as those things that flow forth from angel or man, and constitute spheres around him are not the angel or the man, but are from him, and devoid of his life. These spheres make one with the angel or man no otherwise than that they are concordant; and this they are because taken from the forms of their bodies, which in them were forms of their life. This is an arcanum which angels, with their spiritual ideas, are able to see in thought and also express in speech, but men with their natural ideas are not; because a thousand spiritual ideas make one natural idea, and one natural idea cannot be resolved by man into any spiritual idea, much less into so many. The reason is that these ideas differ according to degrees of height, which were treated of in Part Third.
