5.40

若音下，二、反明。不遍等者，有不聞處，何成圓義？圓者，遍也。失曲等者，無所詮表，何成音義？且如鐘鼓之響普遍邇遐，絲竹之音唯聞咫尺，斯則圓音互非之義也。

[The passage from] "if the sound" onwards is, second, clarifying through the contrary. "Not pervading" and so forth: if there are places where it is not heard, how could it fulfill the meaning of "complete"? "Complete" means pervasive. "Losing the melody" and so forth: if nothing is expressed, how could it fulfill the meaning of "sound"? For example, the ringing of bells and drums carries both near and far, whereas the sound of strings and bamboo flutes is heard only a few feet away; this demonstrates the meaning of "complete" and "sound" mutually negating each other.
