“Bhikkhus, suppose there is a guest house. People come from the east, west, north, and south and lodge there; khattiyas, brahmins, vessas, and suddas come and lodge there. So too, bhikkhus, various feelings arise in this body: pleasant feeling arises, painful feeling arises, neither-painful-nor-pleasant feeling arises; carnal pleasant feeling arises; carnal painful feeling arises; carnal neither-painful-nor-pleasant feeling arises; spiritual pleasant feeling arises; spiritual painful feeling arises; spiritual neither-painful-nor-pleasant feeling arises.”
SN 36.14. Agara Sutta.
