阿彌陀經疏 1.64

1.64

又，舍利下，二、約報示相。又二：一、大小弟子莊嚴；二、生者不退莊嚴。前言莊嚴則莊嚴極樂，此言莊嚴則莊嚴無量，語同意別也。然則弟子是其輔佐，生者是其人民，既二皆無量，故使法王名無量也。望前共有四義：一、光明；二、壽命；三、弟子；四、生者，此四皆無量，是故號阿彌陀也。前二從自，後二從他。初文謂聲聞弟子、菩薩弟子悉無量也。聲聞者，聞四諦聲教而悟道故。

From "Moreover, Śāri[putra]" onward, second, demonstrating the marks based on the fruition. This also has two parts: first, the adornment of greater and lesser disciples; second, the adornment of non-retrogression among those born there. When adornment was mentioned previously, it was the adornment of Sukhāvatī; when adornment is mentioned here, it is the adornment of the Limitless One. The words are the same, but the meanings are distinct. Thus, the disciples are his assistants, and those born there are his people. Since both are limitless, they cause the Dharma King to be named Limitless. Looking back, there are four meanings in total: first, light; second, lifespan; third, disciples; fourth, those born there. These four are all limitless, and therefore he is called Amitābha. The first two pertain to oneself, and the latter two pertain to others. The first text means that both śrāvaka disciples and bodhisattva disciples are all limitless. 'Śrāvakas' are called so because they hear the spoken teachings of the Four Truths and awaken to the path.
