大般涅槃經義記 5.109

5.109

就初段中，先略、後廣。「一切眾生於下苦中橫生樂」等會通昔言，生滅行苦損惱相微故名下苦。「凡夫眾生未覺此苦，於此苦中橫生樂想，故我昔說六觸受樂、乃至意思好法受樂，是故今說與本不異」會今同昔，是於下苦橫生樂故，今所說苦與昔所迷下苦不異。又復我今就彼下苦宣說苦想，與彼橫生樂想不乖，故言不異。

In the first section, it is first brief and then detailed. 'All sentient beings mistakenly give rise to [the conception of] pleasure within inferior suffering' and so forth reconciles the past words; because the characteristics of harm and distress in the suffering of conditioning characterized by arising and ceasing are subtle, it is called inferior suffering. 'Ordinary sentient beings have not yet awakened to this suffering, and within this suffering mistakenly give rise to the notion of pleasure; therefore, I previously spoke of the six contacts experiencing pleasure, up to the mental consciousness experiencing pleasure in good dharmas; therefore, what is spoken now is not different from the original' reconciles the present as identical to the past: because it is mistakenly giving rise to pleasure within inferior suffering, the suffering spoken of now is not different from the inferior suffering that was formerly misunderstood. Furthermore, now, with respect to that inferior suffering, I preach the notion of suffering, which does not contradict their mistakenly giving rise to the notion of pleasure, and therefore it is said to be not different.
