金光明經文句 1.8

1.8

「王舍城」者，《釋論》大出因緣。初立五山中七燒七造，王來居此，故言王舍。又云「他舍被燒，王舍不燒。後悉排云是王舍，即得免燒。自是已來呼為王舍。」觀解，五陰為舍，心王居之，故言王舍。

Regarding the "city of Rājagṛha": The Mahāprajñāpāramitopadeśa extensively sets forth its circumstances. When first established among the five mountains, it burned seven times and was built seven times; the king came to dwell here, hence it was called "the King's Abode" (Rājagṛha). It is also said, "Other houses were burned, but the king's house was not burned. Afterwards, all arranged to claim they were the king's house, and thereby escaped being burned. From then on, it was called 'Rājagṛha'." In contemplative interpretation: the five aggregates are the house, and the mind-king dwells in them; hence it is called "Rājagṛha."
