大毘盧遮那成佛經疏 10.166

10.166

此鄔波計設尼也（空定）弭履相，如前（此文殊使者，名質多也麼，是空是我。下羅是相，猶有相故有我，離相故無我。亦文殊師利定也）。

This is Upakeśinī (emptiness concentration). The mark of mi-ri is as before (this is Mañjuśrī's messenger named Citta. Ma is emptiness, and is "I." Ra below is marks; because there are still marks there is an "I," and because of freedom from marks there is no "I." It is also the samādhi of Mañjuśrī).
