14.364

此中聲亦有爾準知，如前基師解，界者因也即造聲四大是，此大是異熟所生聲非異熟，即當第三傳聲，聲從報生故。

Sound here should also be understood accordingly. As explained previously by Master Ji: 'element' (dhātu) means cause; that is, the four great elements that produce sound. These great elements are fruition, but the sound produced is not fruition; this corresponds to the third transmitted sound, because sound is produced from retribution.
