Master Jiqun: Over three thousand years ago, ancient Greek philosophers roused the world saying: "e;Know thyself!"e; We also need to understand the mind-nature in order to know the true appearance of the world and even become sages. Zhou Guoping: It is in no way unjust for philosophy to be a supporting role of Buddha Dharma in the realm of life enlightenment. Buddha Dharma provides the ultimate solution to the questions of human life.
