無量壽經優婆提舍願生偈註 2.18

2.18

稱彼如來名者，謂稱無礙光如來名也。如彼如來光明智相者，佛光明是智慧相也。此光明照十方世界無有障礙，能除十方眾生無明黑闇，非如日月珠光但破空穴中闇也。如彼名義欲如實修行相應者，彼無礙光如來名號，能破眾生一切無明、能滿眾生一切志願。然有稱名憶念而無明猶在而不滿所願者。何者？由不如實修行，與名義不相應故也。云何為不如實修行與名義不相應？謂不知如來是實相身、是為物身。又有三種不相應：一者信心不淳，若存若亡故；二者信心不一，無決定故；三者信心不相續，餘念間故。此三句展轉相成，以信心不淳故無決定，無決定故念不相續。亦可念不相續故不得決定信，不得決定信故心不淳。與此相違，名如實修行相應。是故論主建言我一心。

'Invoking that Tathāgata's name' means invoking the name of the Tathāgata of Unhindered Light. 'In accordance with that Tathāgata's marks of light and wisdom': the Buddha's light is the mark of wisdom. This light illuminates the worlds of the ten directions without hindrance, capable of removing the dark ignorance of sentient beings in the ten directions, unlike the light of the sun, moon, and pearls, which only dispels darkness in hollow cavities. 'In accordance with the meaning of that name, wishing to practice in accordance with reality': the title of that Tathāgata of Unhindered Light can shatter all ignorance of sentient beings and fulfill all aspirations of sentient beings. Yet there are those who invoke the name and remain mindful, but ignorance remains and their aspirations are not fulfilled. Why is this? Because they do not practice in accordance with reality, and do not correspond with the meaning of the name. What is not practicing in accordance with reality and not corresponding with the meaning of the name? It means not knowing that the Tathāgata is the body of the real mark and the body for the sake of beings. Furthermore, there are three kinds of non-correspondence: first, faith is not genuine, appearing at times and disappearing at others; second, faith is not unified, lacking determination; third, faith is not continuous, interrupted by other thoughts. These three phrases mutually produce one another: because faith is not genuine, there is no determination; because there is no determination, mindfulness is not continuous. It may also be said that because mindfulness is not continuous, one does not attain resolute faith; because one does not attain resolute faith, the mind is not genuine. The opposite of this is called practicing in accordance with reality. Therefore, the author of the treatise states: 'With single-mindedness, I...'
