新華嚴經論 6.65

6.65

第五摩醯首羅天淨土者，如來於彼坐寶蓮華座成等正覺，以為實報。此閻浮提摩竭提國菩提場中成正覺者是化，此為三乘中權教菩薩染淨未亡者說。言此閻浮提及六天等是欲界有漏，彼上界摩醯首羅天是無漏故。為存染淨、彼此未亡，此為權教，未為實說。

Regarding the fifth, the pure land of the Maheśvara heaven: the Tathāgata sits there on a jeweled lotus throne and attains complete, perfect enlightenment, which is taken to be the true reward. His attainment of enlightenment here in the bodhimaṇḍa of the country of Magadha in Jambudvīpa is a transformation [body]. This is preached for the sake of provisional-teaching bodhisattvas within the three vehicles who have not yet extinguished [the duality of] defilement and purity, saying that this Jambudvīpa and the six [desire] heavens are defiled and contaminated in the desire realm, whereas that Maheśvara heaven in the upper realm is uncontaminated. Because it preserves defilement and purity and has not eliminated "this" and "that", this is a provisional teaching, not an ultimate explanation.
