27. Verse 9 And God said, Let the waters under heaven be gathered together to one place, and let the dry land appear; and it was so.

Once a person knows of the existence of the internal man and of the external man, and knows that, contrary to appearance, truths and goods flow in from the internal man, or from the Lord by way of the internal into the external, then the things residing in him as cognitions of truth and good are stored away in his memory and registered among the facts there. For anything that finds its way into the memory or the external man, whether natural, spiritual, or celestial, lodges there as known fact, and from that place it is brought out by the Lord. These cognitions are 'the waters gathered together to one place' and are called 'seas'. But the external man itself is called 'the dry land' and immediately afterwards 'earth', as in the verses that follow.

In the Word, “light” in the highest sense represents Divine Truth: knowledge, ideas, understanding that come to us from the Lord. In lesser degrees -- the light of a lamp, the light of the moon and so forth -- it represents lower levels of truth, ideas and understanding drawn from more earthly sources. Also, the sun in the Word represents the Lord, with its heat representing the divine love and its light representing the divine wisdom. That wisdom flows into our minds and enters our lives in the form of truth -- things we can know and ponder that lead us and help us to be good people. This connection between light and thought is one of many spiritual/natural relationships that's embedded in our common language. People “see the light” when they understand something; we try to “shed some light” by bringing new thoughts to a difficult question; people are “enlightened” when they get new information or a more complete understanding of something. And a light bulb in a cartoon represents an idea!
