Nor (is this objectionable), for by the very reasoning already given about the non-confusion of things-to-be-done, action is produced by an instrument. And it is going and the like that are action in the principal sense, not the perception of color and the like — since in the Vaiśeṣika system that (perception) counts as a quality. Therefore the group of action-faculties must necessarily be admitted.
