Work Against Nature Is To Harm nature

There was a man of 'Sung" who was grieved that his growing corn was not longer, so he pulled it up. Having done this, he returned home, looking very stupid, and said to his people, "I am tired today. I have been helping the corn to grow long." His son ran to look at it, and found the corn all withered. There are a few in the world who do not deal with their passion as if they were assisting the corn to grow long. Some indeed consider it of no benefit to them, and let it alone-they do not weed their corn. They who assist it to grow long pull out their corn. What they do is not long of no benefit to the nature, but it is also injured it.
