菩薩瓔珞本業經 1.93

1.93

「是故於一法界中，有三界報。一切有為法，若凡若聖、若見著、若因果法，不出法界。唯佛一人在法界外，然後為復來入法界藏中，為無明眾生示一切善惡道果報差別無量。

"Therefore, within the single dharmadhātu there are the retributions of the three realms. All conditioned dharmas—whether ordinary or noble, whether views and attachments, whether dharmas of cause and effect—do not extend outside the dharmadhātu. Only the Buddha alone is outside the dharmadhātu; then, for their sake, he enters back into the treasury of the dharmadhātu to reveal to ignorant sentient beings the immeasurable distinctions among the fruits and retributions of all good and bad paths.
