菩薩瓔珞本業經 1.90

1.90

「佛子！一切煩惱以十三為本，無明與十三作本，是以就法界中別為三界報。佛子！見、著二業迷法界中一切色欲心，所起報故分，為欲界報。

"O Son of the Buddha! All afflictions take the thirteen as their root, and avidyā serves as the root for the thirteen; thus, within the dharmadhātu, they are distinguished as retributions of the three realms. O Son of the Buddha! The two karmas of views and attachments are confused about all minds of desire and form within the dharmadhātu; the retributions they give rise to are distinguished as the retributions of the desire realm.
