13.17

非行動為體者，正量部說動名身表，為破此故，說非行動。正量部計有為法中心、心所法及音聲、光明等，許剎那滅，定無行動。身表業色許有動故，非剎那滅。如禮佛等身動轉時，事若未終，此之動色無剎那滅。此身動時，表善惡故，故身表業行動為體。

'It does not have motion as its substance': the Sāṃmitīya school says that motion is called bodily informative [karma]; to refute this, it is said that it is not motion. The Sāṃmitīya school posits that among conditioned phenomena, mind, mental factors, sound, radiance, and the like are accepted to perish in a moment and definitely have no motion. But the matter of bodily informative karma is accepted to possess motion, and hence does not perish in a moment. Just as when bowing to the Buddha or the like, as the body moves and turns, if the action is not yet finished, this matter in motion does not perish in a moment. Since this body when moving informs of good and evil, bodily informative karma therefore has motion as its substance.
