The Tao-te Ching indicates that Taoism has Three Treasures (chapter 67).

The first one is to protect the environment for human existence. The second treasure aims at not squander the natural resources of the earth. Simple life is a Taoist moral norm. The third treasure warns not to destroy the wealth of others nor of its descendants. In Taoist history, Masters always proclaimed that Taoists temples could not be luxurious, therefore in China temples are always simple. Taoism uses Feng Shui to harmonize life and to communicate with the energy of nature in order to preserve Earth's natural system.
