Form depends mostly upon reflection; it is the reflection of the sun in the moon that makes the moon appear round like the sun. All the lower creation evolves by the same law.

A man who has the care of animals begins to resemble them, and we see that the butler of a colonel has the bearing of a soldier, and a maid working in a nunnery in time becomes like a nun.
