'Height' signifies what is inward, and also heaven.

103. The sun in the spiritual world appears at a middle height as distant from the angels as the sun in the natural world does from people. Most people coming from the world bring with them an idea of God as being at a height above their head, and of the Lord as being in heaven among the angels.

They bring with them an idea of God as being at a height above their head because God is called in the Word the Most High, and is said to dwell on high. Consequently they raise their eyes and hands upward when they entreat Him and worship Him - not knowing that by "most high" is meant inmost.

They bring with them an idea of the Lord as being in heaven among the angels because they think of Him only as being like any other man, and some as being like an angel - not knowing that the Lord is the one and only absolute God who rules the universe. If He were to be among the angels in heaven, He could not hold the universe under His gaze and under His direction and government. And if He did not shine before the eyes of those who are in the spiritual world as a sun, it would be impossible for angels to have any light. For angels are spiritual beings, and therefore the only light that is suited to their essence is spiritual light. That there is light in heaven, surpassing by far light on earth, will be seen below where we take up degrees.
