仁王護國般若經疏 2.36

2.36

「九梵」下，二明處。此經三本不同，有一本云「復有萬萬億十八梵天，九梵、三淨、三光、五喜樂天。」又一本中但云「三淨、三光、五喜樂天。」又一本除「五」字，初除「十八梵天」四字，後但有「三」字無「梵」字，蓋譯者出沒耳。言九梵者，謂第四禪九天：一無雲、二福生、三廣果、四無想、五無煩、六無熱、七善現、八善見、九色究竟也。三淨者，是第三禪，有三天，謂少淨、無量淨、遍淨也。三光者，是第二禪，有三天，謂少光、無量光、光音。三梵者，謂初禪，三天，梵眾、大梵、梵輔也。五喜樂天者，即五支，謂覺、觀、喜、樂、一心等也。是四禪中後五淨者，此天義論受喜樂故也云云。

From "nine Brahmā" down, the second explains the place. In this sūtra, three manuscripts differ: one manuscript says, "There are further myriad myriad billions of the eighteen Brahmā heavens: nine Brahmā, three purity, three light, and five joy-and-pleasure heavens." Another manuscript merely says, "three purity, three light, and five joy-and-pleasure heavens." Yet another manuscript omits the word "five," initially omits the four words "eighteen Brahmā heavens," and later only has the word "three" without the word "Brahmā"; this is simply variations across translators. The "nine Brahmā" refers to the nine heavens of the fourth dhyāna: first, Cloudless; second, Arising of Merit; third, Broad Fruit; fourth, Non-perception; fifth, No Torment; sixth, No Heat; seventh, Skillful Appearance; eighth, Skillful Vision; and ninth, Akaniṣṭha (Ultimate Form). The "three purity" is the third dhyāna, which has three heavens, namely Limited Purity, Immeasurable Purity, and Universal Purity. The "three light" is the second dhyāna, which has three heavens, namely Limited Light, Immeasurable Light, and Light-Sound. The "three Brahmā" refers to the first dhyāna, three heavens: Brahmā-pāriṣadya, Mahābrahmā, and Brahmā-purohita. The "five joy-and-pleasure heavens" are the five factors, namely investigation, examination, joy, pleasure, and one-pointedness of mind. As for the latter five pure [heavens] in the fourth dhyāna, these heavens are conceptually discussed as experiencing joy and pleasure, and so forth.
