Khīrasutta
Sāvatthiyaṁ viharati. “Anamataggoyaṁ, bhikkhave, saṁsāro. Pubbā koṭi na paññāyati avijjānīvaraṇānaṁ sattānaṁ taṇhāsaṁyojanānaṁ sandhāvataṁ saṁsarataṁ. Taṁ kiṁ maññatha, bhikkhave, katamaṁ nu kho bahutaraṁ, yaṁ vā vo iminā dīghena addhunā sandhāvataṁ saṁsarataṁ mātuthaññaṁ pītaṁ, yaṁ vā catūsu mahāsamuddesu udakan”ti? “Yathā kho mayaṁ, bhante, bhagavatā dhammaṁ desitaṁ ājānāma, etadeva, bhante, bahutaraṁ yaṁ no iminā dīghena addhunā sandhāvataṁ saṁsarataṁ mātuthaññaṁ pītaṁ, na tveva catūsu mahāsamuddesu udakan”ti.
Mother’s Milk
At Sāvatthī. “Mendicants, this transmigration has no known beginning. No first point is found of sentient beings roaming and transmigrating, shrouded by ignorance and fettered by craving. What do you think? Which is more: the mother’s milk you’ve drunk while roaming and transmigrating for such a very long time, or the water in the four oceans?” “As we understand the Buddha’s teaching, the mother’s milk we’ve drunk while roaming and transmigrating is more than the water in the four oceans.”
