Flowing eternally, incessantly shapechanging [bad word] since the creation of the World
From the crystal-clear source of vitality,
Giving births, giving might. 

Small brook [bad word] a roaring torrent
But colors are gradually fading away
It burns in the devouring fire of Phlegethon 

Rivers, that are slowly passing by
Never are being the same,
But always to the same end,
The predetermined final 

What expects waters falling into the storming seas?
The destination is obscure, but firm.
