This lot has the meaning of "emptying one's mind of energy." It admonishes the parties involved that what they see is not always the truth. There are many phenomena in society that are a mixture of truth and falsehood, and what we see with our eyes and hear with our ears is only the surface, sometimes a false image. We must use wisdom to determine what is right and wrong, what is true and false. Before we do anything, we must carefully consider and verify it again and again. If we are misled by the appearance of something and immediately take it seriously and act rashly, the result will be futile, and we may end up with nothing more than a waste of time and effort.
