經律異相 1.94

1.94

月城郭。廣長千九百六十里。其高亦然。儼然方正遠見故圓。二分天銀一分瑠璃。內外清徹光明遠照。為五風所持。月王坐方二十里七寶宮殿。無量天神光明妓樂前後導從。園池等玩如忉利天。天壽五百歲。子孫相襲以竟一劫。月有虧滿。缺者一角行夜稍稍隱側故見缺減。又云。月城邊有天。其色正青衣服亦青。所在之面青光照城故缺減也。滿者月行稍轉向正。又青色天十五日轉入月城與王遇會。又須彌山南地有大樹。樹名閻浮提。高四千里枝蔭二千里影現月中（出長阿含經第二十二卷又出樓炭經）。

The moon's rampart city is one thousand nine hundred and sixty li wide and long, and its height is the same. It is upright and square, but appears round when seen from afar. Two parts are celestial silver and one part is vaidūrya; inside and outside it is pure and clear, and its light shines far away. It is supported by five winds. The throne of the moon king is twenty li square in a palace of the seven treasures. Boundless gods with bright radiance and courtesan musicians precede and follow in his retinue. Its parks, pools, and amusements 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 moon waxes and wanes: when it wanes, it moves with one corner tilted at night so that it is gradually shadowed and turned sideways, and therefore it is seen as deficient. It is also said that at the side of the moon city there is a god whose color is deep blue and whose clothes are also blue; the side where he resides casts blue light upon the city, and therefore it wanes. When it is full, the moon's course gradually turns upright; moreover, on the fifteenth day the blue god enters the moon city and meets with the king. Furthermore, on the earth south of Mount Sumeru there is a great tree named Jambū, four thousand li high with branches spreading two thousand li of shade, whose reflection appears in the moon.
