復有萬萬億九梵，三淨、三光、三梵，五喜樂天，天定功德定味常樂神通，十八生處功德皆成就。

Furthermore, there were ten thousand times ten thousand koṭis of the nine Brahmā [heavens]—the three Purity, the three Radiance, the three Brahmā—and the five Joyous and Blissful heavens, [endowed with] celestial absorption merits, the taste of absorption, constant bliss, and superknowledges, with the merits of the eighteen birthplaces all completely perfected.
