Your body is the shape lent to you by heaven and earth. Your life is not your possession; it exists through the harmony of energies, and is lent for a time by heaven and earth. Your character and destiny are not your possessions; they are laid down for you by heaven and earth. You travel through life without knowing where you are going; and you are fed, without knowing how food grows. So how can you ever possess anything?
