依起世經云。佛告諸比丘。日天宮殿縱廣正等五十一由旬。上下亦爾。以二種物成其宮殿。正方如宅。遙看似圓。何等為二。所謂金及玻𭹳。一面兩分皆是天金成。清淨光明。一面一分是天玻𭹳成。淨潔光明。有五種風吹轉而行。何等為五。一名為持。二名為住。三名隨順轉。四名波羅呵迦。五名將行。彼日天宮之前別。有無量諸天於前而行。行時各常受樂皆名牢行（依長阿含經云。日天宮牆及地薄如華葩。為五風所持也）又日宮殿中有閻浮檀金。以為妙輦輿。高十六由旬。方八由旬。莊嚴殊勝。天子及眷屬在彼輦中。以天五欲具足受樂。日天子身壽五百歲。子孫相承皆於彼治。宮殿住持滿足一劫。日天身光出照於輦。輦有光明復照宮殿。光明相接出已照曜遍四大洲及諸世間。日天身輦及宮殿有一千光明。五百光明傍行而照。五百光明向下而照。日天宮殿常行不息。六月北行。於一日中漸移北向六俱盧舍（依雜寶藏經有五里）未曾暫時離於日道。六月南行。亦一日中漸移南向六俱盧舍。不差日道。日宮殿六月行時。月天宮殿十五日中亦行爾許。

According to the Qishi jing: The Buddha told the monks, "The palace of the Sun Deva is precisely fifty-one yojanas in length and breadth, and the same from top to bottom. His palace is formed of two kinds of substance: square like a mansion, but appearing circular when seen from afar. What are the two? Namely, gold and crystal. On one side, two parts are formed of divine gold, which is pure and radiant. On one side, one part is formed of divine crystal, which is immaculate and radiant. There are five kinds of wind that blow, rotate, and move it along. What are the five? The first is named Upholding; the second is named Sustaining; the third is named Moving with the Flow; the fourth is named Pravāhaka; the fifth is named Advancing. Before that palace of the Sun Deva, there are separately immeasurable devas walking ahead of it; as they walk, they always experience bliss, and all are named Firm Walkers. (According to the Dīrgha Āgama, the walls and floor of the Sun Deva's palace are as thin as flower petals, and are upheld by the five winds.) Moreover, within the palace of the sun there is a magnificent carriage made of Jambūnada gold, sixteen yojanas high and eight yojanas square, splendidly adorned. The deva prince and his retinue abide in that carriage, fully experiencing pleasure through the five divine sensual desires. The Sun Deva's physical lifespan is five hundred years; sons and grandsons succeed one another, all ruling there. The palace endures for a full kalpa. The radiance of the Sun Deva's body shines forth upon the carriage; the carriage's radiance in turn shines upon the palace; and the radiances, joining together, shine forth and illuminate all four great continents and the various worlds. The Sun Deva's body, carriage, and palace possess one thousand rays of light: five hundred rays shine laterally, and five hundred rays shine downward. The Sun Deva's palace moves constantly without resting. For six months it travels north, gradually shifting northwards by six krośas in a single day (according to the Samyuktaratnapiṭaka-sūtra, this is five li), never departing even for a moment from the sun's path. For six months it travels south, also gradually shifting southwards by six krośas in a single day, not deviating from the sun's path. During the six months when the solar palace travels, the palace of the Moon Deva travels that same amount within fifteen days."
