金光明最勝王經疏 2.129

2.129

贊曰：四佛請陳。文分為三：初四佛俱來、次遣使陳請、後使者傳命。此即初也。問：四佛將往妙幢，其室忽然變座；詣山不言變座，四佛如何以安？答：此中應是釋迦變座，文略不言。問：何故至妙幢室四佛自變，來詣靈山即釋迦變？答：下人不測上來，所以四佛自變；釋迦能知佛至，故變座安。

Commentary: The four Buddhas send their request. The text is divided into three parts: first, the four Buddhas come together; next, they dispatch attendants to convey their request; finally, the attendants convey the message. This is the first. Question: When the four Buddhas were about to go to Ruciraketu's chamber, his chamber suddenly transformed into thrones; when they went to the mountain, no transformation of thrones is mentioned—how were the four Buddhas accommodated? Answer: Here it must be that Śākyamuni transformed thrones, but the text briefly omits mentioning it. Question: Why is it that upon arriving at Ruciraketu's chamber the four Buddhas transformed them themselves, but upon coming to the Vulture Peak it was Śākyamuni who transformed them? Answer: An inferior person cannot anticipate the coming of superiors, therefore the four Buddhas transformed them themselves; Śākyamuni was able to know the Buddhas' arrival, therefore he transformed thrones to accommodate them.
