Controverted Point: That sound is nothing more than a diffusion of initial and sustained mental application.

Theravādin: If this be true, you must affirm no less that sounds from mental contact are solely an irradiation of mental contact; that such as are from feeling are solely an irradiation of feeling. So also for such as are from perception, volition, thought in general, mindfulness, understanding. This you will not do.

Must you not also affirm of a sound that is an irradiation of mental application, that it is none the less to be cognized by hearing, impinges on the ear, comes into the auditory avenue? This you deny; you affirm that such a sound is not cognizable by hearing, etc. How then can you speak of it as sound?
