阿彌陀經通贊疏 2.101

2.101

贊曰：第二正辨得名。而有二義：一、約光明得名；二、約慧命得名。此即初。光有二種：一、內光，即智內照理；二、外光，即身光外照也。此即身光也。金剛不壞之體、無礙解脫之身，如淨瑠璃表裏瑩徹，彼方境物悉現光中，羽之只有一尋，展之動論無量也。《無量壽佛經》云：身多光故乃至無量等光，眾生遇彼光者三垢消滅。若在三塗見光息苦，壽終之後皆得解脫。《大論》云：阿彌陀國諸菩薩眾，身之常光照十萬由旬，若是佛光遍照十方世界。又《觀經》云：彼佛身如百千萬億夜魔天閻浮檀金色，其身六十萬億那由他恒河沙由旬，眉間白毫右旋宛轉如五須彌山，佛眼如四大海水清白分明，身諸毛孔演出光明如須彌山，其佛圓光如百億三千大千世界，於圓光中有五百萬億那由他恒河沙化佛，一一化佛亦有眾無數化菩薩而為侍者。彼佛有八萬四千相，一一相有八萬四千好，一一好有八萬四千光明，遍照十方無量世界，有此光明故號阿彌陀也。

Praise: Second, directly determining the acquisition of the name. There are two meanings: 1. Acquiring the name in terms of light; 2. Acquiring the name in terms of life-span. This is the former. Light is of two kinds: 1. Inner light, namely wisdom inwardly illuminating the principle; 2. Outer light, namely the bodily light outwardly illuminating. This refers to the bodily light. It is an adamantine, indestructible body, a body of unimpeded liberation, like pure lapis lazuli transparent inside and out; the objects and environments of that realm all appear within the light. Folded, it is only one fathom; extended, it amounts to immeasurability. The Amitāyus Sūtra says: 'His body has much light, up to immeasurable light and so forth; sentient beings who encounter that light have their three defilements eradicated. If those in the three wretched destinies see the light, their suffering ceases, and after their lives end, all attain liberation.' The Dazhidulun says: 'The bodhisattvas of Amitābha's land have a constant bodily light illuminating one hundred thousand yojanas; the Buddha's light pervasively illuminates the worlds of the ten directions.' Furthermore, the Guan jing says: 'That Buddha's body is like the Jāmbūnada gold of a hundred thousand kotis of Yāma heavens; his body is sixty thousand kotis of nayutas of Ganges sands of yojanas. The white curl between his eyebrows coils to the right like five Mount Sumerus; the Buddha's eyes are as clear and distinct as the waters of the four great oceans; the pores of his body emit light like Mount Sumeru; that Buddha's nimbus is like a hundred kotis of three-thousand-great-thousand worlds, and within the nimbus are five million kotis of nayutas of Ganges sands of manifested Buddhas, each manifested Buddha also having an assembly of countless manifested bodhisattvas as attendants. That Buddha possesses eighty-four thousand marks; each mark has eighty-four thousand secondary characteristics; each secondary characteristic has eighty-four thousand rays of light, pervasively illuminating the immeasurable worlds of the ten directions.' Possessing this light, he is therefore named Amitābha.
