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.
What's not sangha about the laity?. Monks and non-monks - variously, segregated/separate sleeping quarters, bathroom facilities, sometimes separate meditation halls with donations of money, food, and certain communal luxury goods [tv time], chocolate with no smoking, one alcoholic beverage vs none whatever for monks with English teaching the natives and building materials on the side.
