 While the Tao Te Ching is most famous, there are many other important texts in traditional Taoism. Taishang Ganying Pian ("Treatise of the Exalted One on Response and Retribution") discusses sin and ethics, and has become a popular morality tract in the last few centuries. It asserts that those in harmony with Tao will live long and fruitful lives. The wicked, and their descendants, will suffer and have shortened lives.
