說無垢稱經疏 5.161

5.161

贊曰：下明就座。有二：初明菩薩就座、後明聲聞就座。初中復二：初明自能、後顯他力。此初文也。身座相稱，故名端嚴。

Commentary: Below explains taking seats. There are two parts: first, explaining the bodhisattvas taking their seats; next, explaining the śrāvakas taking their seats. The first further has two parts: first, explaining their own ability; next, revealing the power of another. This is the first text. Because their bodies and thrones matched, it is called "dignified."
