觀無量壽佛經疏 2.12

2.12

三、從在王舍城已下，正明如來遊化之處。即有其二：一、遊王城聚落，為化在俗之眾。二、遊耆山等處，為化出家之眾。又在家者，貪求五欲相續是常。縱發清心，猶如畫水。但以隨緣普益，不捨大悲。道俗形殊，無由共住。此名境界住也。又出家者，亡身捨命，斷欲歸真。心若金剛，等同圓鏡。悕求佛地，即弘益自他。若非絕離囂塵，此德無由可證。此名依止住也。

Third, from "in Rājagṛha" onwards directly clarifies the places where the Tathāgata traveled to transform. There are two: 1. Traveling in the royal city and villages to transform the lay assembly. 2. Traveling on Mount Gṛdhrakūṭa and other places to transform the monastic assembly. Furthermore, as for laypeople, greedy pursuit of the five desires continues constantly. Even if they generate a pure mind, it is like drawing on water. Yet because he accords with conditions to universally benefit, he does not abandon great compassion. The monastic and the lay forms are distinct; there is no way for them to dwell together. This is called dwelling by realm. Furthermore, as for monastics, they disregard body and give up life, sever desires and return to the real. Their minds are like vajra, equal to a round mirror. Yearning for the Buddha stage, they widely benefit self and others. If they do not completely detach from noisy defilement, there is no way this virtue can be verified. This is called dwelling by reliance.
