Classical Chinese · 道德經 (王弼本)
谷神不死，是謂玄牝。玄牝之門，是謂天地根。緜緜若存，用之不勤。
English · James Legge
The valley spirit dies not, aye the same; The female mystery thus do we name. Its gate, from which at first they issued forth, Is called the root from which grew heaven and earth. Long and unbroken does its power remain, Used gently, and without the touch of pain.
