It is said of Lao Tzu that he was when his mother beheld a falling star, and was born sixty two years later when his mother rested beneath a plum tree. He became a scholar and archivist to the imperial court. In time he came to despair of affairs at court and set out for Tibet atop a water buffalo. As Lao Tzu approached the utmost extent of the empire at Hankao pass he was recognized by the gatekeeper Yin Hsi, who besought him not to pass without leaving a record of his teachings. Two days later Lao Tzu returned, handed the gatekeeper the eighty one verses called the Tao De Ching, and disappeared beyond the frontier.
