金剛般若波羅蜜經註解 1.269

1.269

上明應身去來是異，法身無去來是一，佛恐善現有一、異之見，故設喻以釋之。

Above, it was clarified that the nirmāṇakāya having coming and going is different, while the dharmakāya having no coming or going is one; the Buddha, fearing that Subhūti might have the view of oneness or difference, therefore set forth a metaphor to resolve it.
