注大乘入楞伽經 2.54

2.54

自下八行半偈，是如來次第牒領大慧百八句問也。須彌山在大海中，故言須彌巨海山，牒領上須彌也。巨海者，上問中無。洲渚剎土地，領上土地。

From here on, eight and a half verses sequentially summarize and acknowledge Mahāmati's hundred and eight questions. Mount Sumeru is in the great ocean; therefore, he says "Mount Sumeru and the great ocean", summarizing the "Sumeru" above. "Great ocean" was not in the questions above. "Continents, islands, and lands" acknowledges the "lands" above.
