釋禪波羅蜜次第法門 6.80

6.80

二、未來功德者，善修四無量心，若生色界，多作梵王，以無量心廣攝眾生故；若於初禪得，即作初禪王，乃至四禪亦爾。

Second, regarding merits in future lives: If one cultivates the four immeasurable minds well, if born in the form realm, one will mostly become a Brahmā king, because one broadly gathers sentient beings with an immeasurable mind. If attained in the first dhyāna, one becomes the king of the first dhyāna, and so on up to the fourth dhyāna as well.
