大方廣佛華嚴經疏 14.10

14.10

Third, selecting and determining the subject of the question: According to the intent of this question, apart from the tathāgatagarbha it is not admitted that the eight consciousnesses, as that which perfumes and that which is perfumed, possess separate intrinsic entities capable of producing all dharmas; only the tathāgatagarbha is that upon which production relies. Nor can one say that because the eight consciousnesses do not constitute two categories, the mind-nature is termed "one", for they are capable of producing manifold [phenomena], and thus there would be no contradiction. Nor is it that the eighth consciousness serves as the "one nature" which is perfumed into manifold kinds, for there would be no contradiction, since the words "nature of the mind" do not refer to the eighth consciousness. Since it is said in the answer that the dharmatā is originally unproduced, but is manifested as having production—and dharmatā is an alternate name for tathatā—it directly contradicts the phenomena of retribution, and thus the challenge is formulated. Mañjuśrī wished to reveal the principle of the definitive teaching, and therefore took the mind-nature as the basis of his challenge. He wished to have Jñānaprabha answer decisively that the dharmatā manifests production, so that the vast assembly would together realize it, because both the Laṅkāvatāra-sūtra and the Ghanavyūha-sūtra explain this extensively.
