經律異相 1.92

1.92

日城郭。方正二千四十里。其高亦然。光射人眼見之若圓。宮城純金七寶瑩麗無諸瑕。為五風所持。一持。二養。三受。四轉。五調。日王座方二十里。身出光明照耀宮殿。宮殿之光照於城郭。城郭之光下臨下土。無數天神前後導從。音樂自娛無有休息。林觀浴池如忉利天。天壽五百歲。子孫相襲以竟一劫。日城繞須彌山。東方日出。南方望。西方夜半。北方日入。如是右旋更為晝夜。復有長短。日行稍南南方漸長。經六十里。一百八十日北方稍短。復行稍北北方稍長。一百八十日南方稍短（出長阿含經第二十二卷又出樓炭經）。

The sun's rampart city is exactly square, two thousand and forty li on each side, and its height is the same. Its light strikes people's eyes so that it appears round. The palace city is made of pure gold and the seven treasures, lustrous and free of any flaw. It is supported by five winds: first, holding; second, sustaining; third, receiving; fourth, rotating; fifth, regulating. The throne of the sun king is twenty li square. Light emanates from his body, illuminating the palace; the light of the palace illuminates the rampart city; and the light of the rampart city shines downward upon the earth below. Countless gods precede and follow in his retinue, taking their pleasure in music without rest. The groves, pavilions, and bathing pools are like those of the Trāyastriṃśa heaven. The lifespan of the gods is five hundred years; generation follows generation down to the end of a kalpa. The sun city revolves around Mount Sumeru: when it is sunrise in the east, it is midday in the south, midnight in the west, and sunset in the north. Rotating clockwise in this way, it alternates day and night. There is also variation in length: when the sun travels slightly south, the south gradually grows longer by sixty li, and for one hundred and eighty days the north grows slightly shorter; when it travels slightly north again, the north gradually grows longer, and for one hundred and eighty days the south grows slightly shorter.
