78.27

疏「定有即常定無則斷」者，亦《中論》偈。偈云「定有則著常，定無則著斷。是故有智者，不應著有無。」言「俱亦是二」者，謂有無俱者，則二見相違，亦不離亦斷亦常言故。「雙破二見」者，故經云「諸佛不說有斷常法」。疏「故雖空不斷」下，亦《中論》偈。論云「雖空亦不斷，雖有而不常，罪福亦不失，是名佛所說。」

Regarding the Commentary's stating, "Definite existence is permanence; definite nonexistence is annihilation": this is also a verse from the Madhyamakaśāstra. The verse states: "Definite existence grasps at permanence; definite nonexistence grasps at annihilation. Therefore, those who have wisdom should not grasp at existence or nonexistence." As for the phrase "Both is also twofold": it means that if both existence and nonexistence [are affirmed], then the two views contradict each other, and it does not depart from the expressions of both annihilation and permanence. As for "simultaneously demolishing both views": therefore the sūtra states, "The buddhas do not speak of dharmas of annihilation or permanence." Regarding the Commentary's stating from "Therefore, although empty, it is not annihilated" onward: this is also a verse from the Madhyamakaśāstra. The śāstra states: "Although empty, it is also not annihilated; although existent, it is not permanent; sins and merits are not lost—this is what is spoken by the Buddha."
