觀無量壽佛經疏 3.126

3.126

八、從見此事者下，至攝諸眾生已來，正明功呈不失、觀益得成。即有其五。一明因觀得見十方諸佛。二明以見諸佛故結成念佛三昧。三明但觀一佛即觀一切佛身也。四明由見佛身故即見佛心也。五明佛心者慈悲為體，以此平等大慈普攝一切也。

Eighth, from "Those who see this matter" down to "embraces all sentient beings," it properly explains that the effort presented is not lost, and the benefits of contemplation are successfully achieved. There are five points: first, it explains that due to contemplation one comes to see the buddhas of the ten directions; second, it explains that because one sees all buddhas, one fulfills the samādhi of recollecting the Buddha; third, it explains that simply contemplating one buddha is contemplating the bodies of all buddhas; fourth, it explains that by seeing the Buddha's body, one therefore sees the Buddha's mind; fifth, it explains that the Buddha's mind has compassion as its essence, and with this impartial great compassion universally embraces all.
