說無垢稱經疏 4.402

4.402

贊曰：明現神力，一覩良田、二見物變。此覩良田也。世界虛幻，故名陽炎。佛田第一，難勝如來。

Commentary: Explaining the manifestation of supernormal power: first, beholding the fertile field; second, seeing the object transform. This is beholding the fertile field. The world is illusory, hence called "Mirage". The Buddha-field is foremost: Duṣprasaha Tathāgata.
