說無垢稱經疏 6.118

6.118

贊曰：下第五段，此問彼佛。有二：初問、後答。此問也。即階小位，亦有不知，故試問言汝等知不。

Commentary: The fifth section below is asking about that Buddha from this world. It has two parts: first, the question; second, the answer. This is the question. Even those on lesser stages might not know, so he tests them by asking, "Do you know or not?"
