觀無量壽佛經疏 4.135

4.135

七、從無量諸天已下，正明前厭苦緣中釋梵護世諸天等，從佛王宮臨空聽法。或見釋迦毫光轉變，或見彌陀金色靈儀，或聞九品往生殊異，或聞定散兩門俱攝，或聞善惡之行齊歸，或聞西方淨土對目非遠，或聞一生專精決志，永與生死分流。此等諸天既聞如來廣說希奇之益，各發無上之心。斯乃佛是聖中之極，發語成經，凡惑之類蒙飡，能使聞之獲益。

Seventh, the passage from "immeasurable devas" downward directly clarifies that, during the previous condition of revulsion toward suffering, Śakra, Brahmā, the world-protecting devas, and others followed the Buddha to the royal palace and listened to the Dharma from the sky. Some saw Śākyamuni's ūrṇā-ray transforming, some saw Amitābha's golden spiritual form, some heard of the distinctive differences among the nine ranks of rebirth, some heard that both meditative and non-meditative gates embrace all, some heard that good and evil actions converge together, some heard that the Western Pure Land before their eyes is not far away, and some heard that a single lifetime of dedicated, resolute determination parts forever from the stream of birth and death. Having heard the Tathāgata extensively expound these extraordinary benefits, these devas each gave rise to the unsurpassed mind. This is because the Buddha is the ultimate among sages: his words become sūtras; when ordinary and deluded beings partake of them, they are enabled to obtain benefit upon hearing.
