The huntsman, who comes along to secure and drink the feverish milk of this animal that is all but a rotting carcass, seriously endangers his own well being.
So, young men, do not look upon this dying, decaying world to feed and support you.

You must feed and support it.

Carry fresh, warm, invigorating blood in your veins to inject into the veins of the world.

This is far safer and nobler than sticking the lance into the swollen veins of the world, to draw forth its putrid blood for your own use.

I not only exhort you but I warn you.
