觀無量壽佛經疏 3.121

3.121

五、從無量壽佛下，至攝取不捨已來，正明觀身別相光益有緣。即有其五。一明相多少。二明好多少。三明光多少。四明光照遠近。五明光所及處偏蒙攝益。

Fifth, from "Amitāyus Buddha" down to "embracing and not abandoning," it properly explains contemplating the specific marks of the body and the benefit of the light toward those who have karmic connection. There are five points: first, it explains the number of major marks; second, it explains the number of minor marks; third, it explains the amount of light; fourth, it explains the reach of the illuminating light; fifth, it explains that where the light reaches, it especially bestows the benefit of embracing.
