首楞嚴義疏注經 3.200

3.200

「是故當知，耳聲為緣生耳識界，三處都無，則耳與聲及聲界三，本非因緣、非自然性。」

"Therefore, one should know that ear and sound serving as conditions produce the ear-consciousness realm; all three loci are utterly nonexistent. Thus ear, sound, and the sound realm—these three are originally neither causes and conditions nor a spontaneous nature."
