2.22

六、念天。念天者，謂四天王天，乃至他化自在天。復有四種天：一名天、二生天、三淨天、四生淨天，如是等果報清淨，利安一切，是為念天。

6. Recollection of the devas: As for recollection of the devas, it refers to the heaven of the Four Heavenly Kings up to the heaven of Mastery over the Transformations of Others. Furthermore, there are four kinds of devas: first, devas by name; second, devas by birth; third, pure devas; fourth, devas pure by birth. Such retributions are pure and benefit and pacify all. This is recollection of the devas.
