4.190

真空等者。雖即諸法皆空，非謂一向非相，但以離執真空不斷故，故云亦無非法相。

On 'True emptiness…' and so forth: Although all phenomena are empty, this does not mean they are entirely non-characteristics; it is only that through being free from clinging, true emptiness is not severed; hence it says 'nor is there the characteristic of non-phenomena'.
