[123] "Bhikkhus, I will teach you a dyad. Listen to it. And what, bhikkhus, is the dyad? The eye and forms, the ear and sounds, the nose and odours, the tongue and tastes, the body and tangibles, and the mind (citta)* and dhammas — this, bhikkhus, is called the dyad. Bhikkhus, if anyone should say: 'Having rejected this dyad, I will make known another dyad' — that would be for him a mere basis of words; and when questioned he would not be able to make good his assertion, and further, he would meet with vexation. For what reason? Because, bhikkhus, that would not be within his domain."
The Ninth.
*Here "mano" (the mind as sense faculty); rendered "mind" per context of the six sense bases (āyatana).
