The cliff represents danger. If we fall into the cliff, it warns us of a disastrous ending of any kind. If we fall into the cliff, but we cannot get out of it, means that there is a possibility to break apart with many difficulties of the disaster. The same occurs if we pass over the cliff by a fragile bridge. If we see the precipice but we don´t fall from it, we are on time to avoid the disaster.
