21.103

言若一切法，意識所識性，是名一切同類可得相者，如立聲常是意識識故，若爾意識則識一切諸法，為如虛空是意識識故聲是其常，為如瓶等是意識識故聲是無常。

Regarding the statement, "If all dharmas are cognised by mental consciousness, this is called the characteristic of being obtainable in all things of the same class": for example, establishing "Sound is eternal, because of being cognised by mental consciousness." If so, mental consciousness cognises all dharmas. Is sound eternal like empty space because of being cognised by mental consciousness, or is sound impermanent like a pot and the like because of being cognised by mental consciousness?
