大般涅槃經義記 4.329

4.329

第二段中，先救地獄、次救餓鬼、後救畜生。救地獄中，文別有四：一放光救濟八大獄中苦惱眾生。二出音聲說如來藏，言生有性令生人天。三放光救濟眷屬獄中苦惱眾生。前八地獄各別有其十六眷屬，謂八寒氷及八炎火。彼一一獄，面各有四，謂二寒氷及二炎火，故有十六。然今文中偏舉寒氷，無八炎火。八中，前四就聲彰名，「阿波波」等並是寒聲；「優鉢羅」等就色彰名，凍諸罪人身體紅赤，似優鉢羅，即以為名；餘亦如是。此等遇光皆悉除滅。四出音聲說如來藏令生人天。下救餓鬼、畜生之中皆先放光，後出音聲，以如來藏眾生體實，故偏說之。眾生聞之故離三塗，得生人天。

In the second passage, it first saves the hells, next saves the hungry ghosts, and finally saves animals. In saving the hells, the text has four distinct parts: first, emitting light to save the tormented sentient beings in the eight great hells. Second, uttering sounds to preach the tathāgatagarbha, saying that sentient beings possess the nature [of buddhahood], causing them to be reborn among humans and devas. Third, emitting light to save the tormented sentient beings in the subsidiary hells. Each of the aforementioned eight hells has its sixteen subsidiary hells, namely eight of cold ice and eight of blazing fire. Each of those hells has four sides, each with two of cold ice and two of blazing fire, thus making sixteen. However, here in the text it singles out the cold ice, without mentioning the eight blazing fires. Among the eight, the first four are named after their sounds, "apapa" and so forth being the sounds of cold; "utpala" and so forth are named after colors, the bodies of the sinners being frozen red, resembling an utpala, which is taken as their name; the rest are also like this. Meeting this light, all these are eliminated. Fourth, uttering sounds to preach the tathāgatagarbha, causing them to be reborn among humans and devas. Below, in saving the hungry ghosts and animals, in each case it first emits light and later utters sounds; because the tathāgatagarbha is the true substance of sentient beings, it is specifically spoken of. Hearing it, sentient beings therefore leave the three wretched realms and attain rebirth among humans and devas.
