Ching Ch'ing, a Chinese Ch'an master, asked a monk:
-What is the sound outside?
The monk answered:
-That is the sound of rain.
The master said:
-Sentient beings are upside down, they lose themselves in pursuit of things.
When you begin to see yourself as a stranger in a strange land and belongeth not to the empire (all hail, ha ha ha) you find that you "render unto Caesar what is Caesars and unto God what is Gods." You begin to live the life interior upon which all manifestation plays out, yet on the outside "when in Rome do as the Romans do."
