金光明最勝王經疏 2.221

2.221

贊曰：即彼第三無二為相。有三無二：一、有無無二；二、為無為無二；三、一切佛無二。此言同者，即無二義。諸佛體皆同，即是總句，亦是有無無二。諸佛無二之別句，謂有無無二為相，由一切法無所有故。釋意：於法身上遍計無，故非有相；以空所顯自性，故非無相。「諸佛無作者」下，顯為無為無二。亦復本無生者，顯應化身有為無為無二相。故論云「由業煩惱非所為故，名無作者。既非煩惱作，亦非惑業生，故云無生。亦顯自性法身，體自本有，非新生作。」所說法亦爾者，因釋說法亦復無差，諸佛如來同事業故。又解：此文釋前能救護世間。若非說法，何能救護？故此經下多云「此經流布於世間中有多利益」。

The commentary states: This is that third mark of non-duality. There are three non-dualities: first, the non-duality of existence and non-existence; second, the non-duality of conditioned and unconditioned; third, the non-duality of all Buddhas. The word 'identical' here has the meaning of non-duality. 'The Buddhas are all identical in essence' is a general phrase, and also refers to the non-duality of existence and non-existence. The specific phrase for the non-duality of the Buddhas states that non-duality of existence and non-existence is its mark, because all phenomena do not exist at all. The meaning explained: on the dharmakāya, imaginary construction is non-existent, so it does not have the mark of existence; because its nature is revealed through emptiness, it does not have the mark of non-existence. Below 'the Buddhas have no agent', it reveals the non-duality of the conditioned and unconditioned. 'And originally have no arising' reveals the mark of the non-duality of conditioned and unconditioned in the nirmāṇakāya. Thus the treatise states: 'Because they are not produced by karma and affliction, they are called having no agent. Since they are not produced by affliction, nor generated by delusion and karma, they are called having no arising. It also reveals that the dharmakāya of essential nature is fundamentally existent in essence, not newly produced.' 'And so is the Dharma they expound' explains in passing that the exposition of the Dharma is also without difference, because the Buddhas, the Tathāgatas, share identical activities. Another explanation: this text explains the previous 'able to rescue and protect the world'. If not by expounding the Dharma, how could they rescue and protect? Therefore, below in this sūtra it frequently states: 'This sūtra circulating in the world brings great benefit.'
