大方便佛報恩經 6.48

6.48

答曰：「色身是法身器故，法身所依故，若害色身則得逆罪。不以色身是佛，故得逆罪。」

Answer: "Because the physical body is the vessel of the dharmakāya and that upon which the dharmakāya relies, harming the physical body results in an unpardonable sin. It is not because the physical body is the Buddha that one incurs an unpardonable sin."
