持因中，由隨大種等量不壞者，亦依同聚四所造義，擊質發聲聲大質小故，或五境附質皆等質量疎遠已去方大於質。

Regarding the sustaining cause (dhṛti-hetu), in [the phrase] "because it does not deteriorate, having an equal measure with the great elements," it is also based on the meaning of being produced by the four [great elements] within the same aggregation: because striking a physical body produces sound, sound is large while the physical body is small; alternatively, when the five sense objects adhere to a physical body, they are all equal to the measure of the physical body, and only when separated at a distance do they become larger than the physical body.
