Dhammapada · 23.6

Middhī yadā hoti mahagghaso ca, niddāyitā samparivattasāyī;Mahāvarāhova nivāpapuṭṭho, punappunaṃ gabbhamupeti mando.

Middhi yada hoti mahagghaso ca, niddayita samparivattasayi; Mahavarahova nivapaputtho, punappunam gabbhamupeti mando.

When one is drowsy, a great eater, sleeping and rolling from side to side — like a great hog fattened on swill — that dull one is born again and again.
