CC Ādi 16.82

ambujam ambuni jātaṁ kvacid api na jātam ambujād ambu
mura-bhidi tad-viparītaṁ pādāmbhojān mahā-nadī jātā
Word for word: 
ambujam — lotus flower; ambuni — in the water; jātam — is grown; kvacit — at any time; api — certainly; na — not; jātam — grown; ambujāt — from a lotus flower; ambu — water; mura-bhidi — in Kṛṣṇa, the killer of Murāsura; tat-viparītam — just the opposite of that; pāda-ambhojāt — from the lotus flower of His feet; mahā-nadī — the great river; jātā — has grown.
Translation: 
“ ‘Everyone knows that lotus flowers grow in the water but water never grows from a lotus. All such contradictions, however, are wonderfully possible in Kṛṣṇa: the great river Ganges has grown from His lotus feet.’
