below (earth) hemisphere

What does below (earth) hemisphere mean in the natal chart?

Most of your planets sit in the lower half of your chart, which tends to pull your life inward. Home, family, your inner world — that's where the things that matter to you actually happen, often out of public view. There's real depth in that. The only thing to watch is pulling back so far that the more outward, visible side of your life — the part you also owe something to — never quite gets built. You can have both; the quiet doesn't have to mean hidden.
