"Why, etc.": concluding into the doubt. Nirvāṇa is the meaning of unmoving asaṃskṛta. As the earlier text says: "If someone says that the Tathāgata comes, goes, sits, or lies down, they do not understand the meaning of what I say. The Tathāgata neither comes from anywhere nor goes anywhere; therefore he is called the Tathāgata." This, then, is the Buddha's entry into nirvāṇa. The point is: nirvāṇa is serene quietude, while preaching the Dharma is clamorous activity; activity and quietude are mutually opposed, so how can both coexist? The sūtra's interrogation means: by what principle does the Buddha constantly speak without obstructing nirvāṇa, as stated in the treatise? The commentary's explanation means: the constant Buddha possesses wondrous wisdom, contemplating all phenomena as empty like dreams, illusions, and the like; although manifesting the expounding of the Dharma resembling saṃskṛta marks, he eternally abides in the principle of non-action in nirvāṇa—what further doubt could there be? If one does not explain this as severing doubt outside of the treatise, this text merely faults defilement in preaching the Dharma. The interrogation means: by what principle, at the time of preaching the Dharma, does one not grasp at marks and succeed in tallying with tathatā, unmoving and undefiled? The explanation means: one merely contemplates all saṃskṛta marks as being like dreams, illusions, and the like; naturally, regarding speech, one neither grasps nor clings, tallying with tathatā without movement or vikalpa.
