說無垢稱經疏 4.81

4.81

贊曰：五空告。有三：初說真佛無疾、次顯化佛有疾所由、後勸取乳。此初文也。真身者報身也，是實功德，從因修生，故名真身。或法報佛皆名真身，非權迹故。舊經無此。如居士言，世尊真身，實無諸疾。

Commentary: Fifth, the announcement from the sky. There are three parts: first, stating that the true Buddha has no disease; second, revealing the reason why the nirmāṇa-buddha displays disease; and third, encouraging him to fetch the milk. This is the first passage. The 'true body' is the saṃbhogakāya; it is true merit produced from cultivation of causes, hence called the true body. Alternatively, both the dharma- and saṃbhoga-buddhas are called the true body, because they are not provisional traces. The older translation lacks this. As the lay practitioner said, the World-Honoured One's true body truly has no disease.
