Kuan Yin Liezi

"Kuan Yin spoke to the Master Liezi, saying: 'If speech is sweet, the echo will be sweet; if speech is harsh, the echo will be harsh. If the body is long, the shadow will be long; if the body is short, the shadow will be short. Reputation is like an echo, personal experiences like a shadow. Hence the saying: "Heed your words, and they will meet with harmonious response; heed your actions, and they will find agreeable accord." Therefore, the Sage observes the origin in order to know the issue, scrutinizes the past in order to know the future. Such is the principle whereby he attains foreknowledge."
