分別功德論 1.10

1.10

何謂眾生不可思議？或云劫燒後，水補火處，隨嵐吹造宮殿訖，下有地肥。光音天上諸天輩，遊戲至地，漸甞地肥，遂便身重不能復還。食多化為女。轉減至薄餅、粳米，失神足光明，還復為人。善行生天、惡行三塗，流轉五道無有常准。正使欲窮盡一人根本所由，尚不能知，況復一切眾生而可思度也。是為眾生不可思議也。

What is meant by living beings being incomprehensible? Some say that after the kalpa destruction by fire, water replenishes the place of fire, and the vairambha wind blows to create palaces; after this is completed, below there is the earth essence. The devas of the Ābhāsvara Heaven, roaming playfully down to the earth, gradually tasted the earth essence, and thereupon their bodies grew heavy so that they could not return. Those who ate much transformed into women. Gradually this diminished to thin cakes and non-glutinous rice, they lost their ṛddhi and radiance, and reverted to being human beings. Virtuous conduct leads to rebirth in the heavens, while evil conduct leads to the three destinies; transmigrating through the five realms, there is no fixed rule. Even if one wished to trace to the very bottom the origin of a single person, one still could not know it; how much less could all living beings be conceived? This is why living beings are incomprehensible.
