淨名經集解關中疏 2.440

2.440

阿閦此云無動。雖復變化萬形而實相常寂故名也。將證淨名勝德。以即經故取佛而現土。因立品名耳。又據前半品應見如來。以後半品顯跡證經故從後立名也。

"Akṣobhya" is translated here as "Immovable." Although he transforms into myriad forms, the true mark is constantly tranquil, hence his name. In order to verify Jingming's superior virtue, because of the sūtra itself, he brings forth the Buddha and manifests the land, therefore establishing the chapter's name. Furthermore, based on the first half of the chapter, it should be called 'Seeing the Tathāgata,' but because the latter half reveals the traces and verifies the sūtra, the name is established following the latter part.
