If we want to avert the worldwide decline of morality, the downfall of nations and the extinction of mankind, we must find a fundamental solution, make a fresh start, change the policy, and be good models for others. In particular, national leaders and top government officials must take the lead, setting an example by not craving wealth and sensual pleasures, and by honoring their own integrity. We must first reform ourselves and before we can teach and influence others. The ancients said, "The preferences of the ruler will certainly be adopted by their subordinates." That is to say, no matter what the ruler is fond of, be he an emperor of the past or a present-day leader, the civilians below will follow his example. The ancients also said, "The virtue of a superior person is like the wind, while the virtue of a lowly person is like the grass. The grass must bend when the wind blows." The breeze blowing across the grass makes it bend over. I sincerely hope that today's teachers, scholars, clergymen, doctors, lawyers and scientists will serve humanity without asking for any reward. If you can really do that, then there will be no more wars in the world and humanity will enjoy true happiness. If we can successfully refrain from fighting, being greedy, seeking, being selfish, pursuing personal benefit, and telling lies, then even if the world does not want to be peaceful, there will still be peace. If you don't believe it, I implore you to give it a try!
