When something good happens, thats good but it will result in bad.
When something bad happens, thats bad but it will result in good.
You cannot have good without the bad.
Any time you try to eliminate the bad, Tao will punish you with more bad.
It is the law of nature that evil must exist together with good.
Japanese people thought:
"We are going to create perfect society. Japan is the most rich country. Japan is most safe. Japan has least murders. Thus, Japan will be perfect."
However Japan: lowest birth rates, highest suicide rates.
Praise Tao's revenge!
Praise Tao's revenge upon Japan!
Japan tried to create best society and ended up creating a very bad country which cant even reproduce.
Thats how Tao punishes those who reject the natural order of good and evil.
