“Bhikkhus, I will teach you the origination and the passing away of the four establishments of mindfulness. Listen to that.
“And what, bhikkhus, is the origination of the body? With the origination of nutriment there is the origination of the body. With the cessation of nutriment there is the passing away of the body.
“With the origination of contact there is the origination of feeling. With the cessation of contact there is the passing away of feeling.
“With the origination of name-and-form there is the origination of mind. With the cessation of name-and-form there is the passing away of mind.
“With the origination of attention there is the origination of phenomena. With the cessation of attention there is the passing away of phenomena.” sn.v.185
