12.3. Of Sound as Result of Karma
Theravādin: Now what can rightly be predicated of a “result of karma”? Such a result is a matter of feeling, pleasant, painful, or neutral; it is conjoined with feeling of these three kinds; it is conjoined with mental contact, feeling, perception, volition, thought; it goes with a mental object; with it go adverting, ideating, co-ordinated application, attention, volition, anticipation, aiming. Is sound anything of this kind? Is it not rather the opposite”?
“He through having wrought, having accumulated, having piled up, having increased such karma, becomes reborn with the voice of a Brahma god, like that of the karavika bird.”
Hence surely sound is a specific result of karma.
