大般涅槃經義記 6.254

6.254

初四偈中，前二明佛斷煩惱障，故得安眠，於中前偈明斷煩惱，後偈明由斷煩惱故證大涅槃，「若得涅槃」是其自德，「演說深義」明利他德，「名婆羅門」總以結歎，自淨淨他故得稱為真婆羅門；第三一偈離業故安，遠離三耶，身、口、意淨；第四一偈除苦故安，「身心無煩」正明離苦，「安住靜」等明其得樂。

Among the first four verses, the first two explain that the Buddha cuts off the affliction-hindrance and therefore attains peaceful sleep. Within these, the former verse explains cutting off afflictions, and the latter verse explains that due to cutting off afflictions, he realizes Mahāparinirvāṇa. "If one attains nirvāṇa" is his personal virtue; "proclaiming the profound meaning" explains his virtue of benefiting others; "he is called a brāhmaṇa" summarizes in praise: purifying oneself and purifying others, he therefore attains being called a true brāhmaṇa. The third verse [explains] being peaceful because of leaving behind karma: staying far away from the three邪 [evils], with purity of body, speech, and mind. The fourth verse [explains] being peaceful because of removing suffering: "Body and mind free from distress" directly explains leaving suffering; "peacefully abiding in stillness..." and so forth explain his attainment of bliss.
