仁王經疏 2.455

2.455

釋曰：自下第二問答分別說法不二。於中有二：先問、後答。此即問也。此問意云：若一切法如，如中無文字。云何諸佛依於文字行諸法相？

The commentary states: From here below, the second part consists of questions and answers differentiating how the expounding of the Dharma is non-dual. Within this there are two: first the question, then the answer. This is the question. The meaning of this question is: If all dharmas are like [suchness], within suchness there are no words or letters. How is it that the buddhas, relying on words and letters, practice the marks of all dharmas?
