If the water in the lake gathers until it rises above the earth, there is danger of a break-through. Precautions must be taken to prevent this. Similarly where men gather together in great numbers, strife is likely to arise; where possessions are collected, robbery is likely to occur. Thus in the time of Gathering Together we must arm promptly to ward off the unexpected. Human woes usually come as a result of unexpected events against which we are not forearmed. If we are prepared, they can be prevented.
