If you realize that all things change, there is nothing you will try to hold on to. If you are not afraid of dying, there is nothing you cannot achieve
LaoziKnowing others is wisdom; Knowing the self is enlightenment; Mastering others requires force; Mastering the self needs strength.
LaoziThe Tao gives birth to One. One gives birth to yin and yang. Yin and yang give birth to all things... The complete whole is the complete whole. So also is any part the complete whole... But forget about understanding and harmonizing and making all things one. The universe is already a harmonious oneness; just realize it.
Laozi
