In the Bible, things that are lower down, or under, physically, generally represent things that are lower or more external spiritually. In some cases, the lower things have been separated and put away to protect the good, but in others, it can mean that a less exalted idea or good desire is supporting a more exalted one.

They have reference to the uses of those organs, which are hidden, and also removed from knowledge; for the reason is a dispensation of Providence, to prevent things which in themselves are most heavenly from being damaged by filthy thoughts belonging to lasciviousness, whorings, and adultery. These thoughts are called forth in many people as soon as those organs are named. From theArcana Coelestia 5055.
