“When you realize that wealth and status in society are temporary and joy and happiness does not depend on them, when you realize that you can only eat so much and the abundant wealth you own will be left behind with your body after death, when you realize that you can only drive one car and live in one house at a time, when you realize that the external materials are temporary and joy does not depend on the external but relies on internal peace;when you realize these: then life will have a different purpose, the purpose to live in joy, to end the suffering of others, to contribute to nature and the society, and to bring the violent world a peaceful change. “
