Agāra sutta: A Guest House

“Mendicants, suppose there was a guest house. Lodgers come from the east, west, north, and south. Aristocrats, brahmins, peasants, and menials all stay there.

In the same way, various feelings arise in this body: pleasant, painful, and neutral feelings. Also pleasant, painful, and neutral feelings of the flesh arise. Also pleasant, painful, and neutral feelings not of the flesh arise.”
