Arcana Coelestia #62
62. The stages and states of the regeneration of man - both of mankind and of the individual person - divide into six and are called the days of his creation. Gradually from being no man at all, he first becomes something, though only little, then something more, until the sixth day is reached, when he becomes 'an image'.
Under
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.
