說無垢稱經疏 2.258

2.258

贊曰：此舉喻顯。寶莊嚴佛，他受用身。寶莊嚴土，即無漏土。佛身不改，唯土變淨，舉他報土以喻化土。或假喻顯，佛舉寶身，其土亦爾。

Commentary: This adduces a simile to illustrate the point. The Buddha Ratnavyūha is a parasambhoga-kāya. The Jewel-Adorned Land is an anāsrava land. The Buddha's body was not altered; only the land changed to purity, adducing another's reward land to serve as a simile for an emanation land. Or it is a provisionally adduced simile: the Buddha showed a jewel-like body, and his land was likewise.
