The Tao Te Ching is a Taoist philosophical treatise. Lao Tzu, a great Ancient Chinese philosopher and teacher, is considered to be the author of this book. We owe this book to an unnamed guardian who kept safe the far western borders of a country, Zhou in the fifth century BC. The legend says that exhausted from misunderstanding Teacher with a tired heart went on his last journey to die in a dessert. The guardian recognized great Lao Tzu, called him by name and, nobody knows how, persuaded the wise man to tell a world about Dao and De. "When you said Dao, you said nothing", the teacher replied. And you were wrong: five thousand words, that contains this book, have been existing for two and a half thousand years. . .
