Over the earth, the lake:
The image of Gathering Together.
Thus the superior man renews his weapons
In order to meet the unforeseen.

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.
