菩薩從兜術天降神母胎說廣普經 1.75

1.75

「或有菩薩入慈三昧，遍滿東方無限無量阿僧祇恒河沙等剎眾生之類，慈愍愛念欲令解脫；譬如恒河沙中取一沙，過恒河沙國土下一沙，如是盡恒河沙慈心不盡，菩薩發願堅固難動。設有人來取菩薩身臠臠割截，即時彌滿三千大千國土，血變為乳如母念子，是為菩薩行慈三昧，即於胎中成無上道。

"Or there are bodhisattvas who enter the samādhi of benevolence, pervading the east throughout infinite, immeasurable, asankhyeya realms, equal to the sands of the Ganges, toward the categories of sentient beings, feeling benevolent pity and affectionate care, wishing to bring about their liberation. Just as taking one grain of sand from the sands of the Ganges, passing lands equal to the sands of the Ganges, and depositing one grain, in this way exhausting the sands of the Ganges, their benevolent mind is not exhausted; the bodhisattva's vow is firm and unshakeable. Even if someone comes and takes the bodhisattva's body, slicing it piece by piece, immediately filling the trichiliocosm, the blood transforms into milk like a mother caring for her child: this is the bodhisattva practicing the samādhi of benevolence, immediately accomplishing the unsurpassed Path within the womb.
