俱舍論記 22.35

22.35

「於一切是諦至非聖說是樂」者，釋。此四諦理，於凡及聖一切皆諦，性無倒故。然唯聖者實見，非凡，是故經中但名聖諦，非是非聖諦。凡雖觀諦，非是決定，而容後時顛倒見故。如有頌言：諸聖者說涅槃是樂，非聖者說涅槃為苦。如外道云：我見世間無一目者尚以為苦，況彼涅槃諸根總滅而得有樂？故計為苦。有漏之法聖說為苦；非聖於中妄說樂受，唯是其樂，故成顛倒。

Regarding "To everyone it is a truth... the non-noble speak of it as pleasure": this is the explanation. The principle of these four truths is true to everyone, both ordinary beings and nobles, because its nature is non-erroneous. However, only the nobles truly see it, not ordinary beings; therefore, in the sūtras they are only called noble truths (āryasatya), not non-noble truths. Although ordinary beings observe the truths, it is not definitive, and they may later harbor inverted views. As a verse states: "The noble ones say nirvāṇa is pleasure; the non-noble say nirvāṇa is suffering." As the non-Buddhists say: "I see that having only one eye in the world is still considered suffering; how much more so in that nirvāṇa where all sense faculties are completely extinguished could there be any pleasure?" Thus they consider it suffering. The nobles speak of sāsrava phenomena as suffering; the non-noble mistakenly speak of pleasant feeling within them as solely pleasurable, and thus it becomes an inversion.
