The specific date of birth of Lao Tzu is unknown. Legends vary, but scholars place his birth between 600 and 300 B.C.E. Lao Tzu is attributed with the writing of the "Tao-Te Ching," (tao-meaning the way of all life, te-meaning the fit use of life by men, and ching-meaning text or classic). Lao Tzu was not his real name, but an honorific given the sage, meaning "Old Master."
Legend says that in the end Lao Tzu, saddened by the evil of men, set off into the desert on a water buffalo leaving civilization behind. When he arrived at the final gate at the great wall protecting the kingdom, the gatekeeper persuaded him to record the principles of his philosophy for posterity. The result was the eighty-one sayings of the "Tao-Te Ching." This ancient Chinese text is the world's most translated classic next to the Bible.
