An abyss represents a hazard. If we fall into it, that warns us a disastrous ending of any kind. If we fall but can get out, it means that there is a possibility to be separated with difficulty from a disaster. The same happens if we pass over the abyss by a fragile bridge. If we see it but we do not fall in it, we are on time to avoid bad things.
