give yourself over to the wolf. let it eat the parts of you that are sick, that are damaged beyond salvage. let the wolf in and let it clean house, and let it leave again. the wolf knows which parts must be swallowed. you do not need what it takes, and where it bites you the wounds will heal. let the wolf in and let it eat you, and let it leave again.
You could also give yourself to the maggots. They eat dead flesh first, and will leave the living tissue alone if you just make sure to not let them feed too long. People have survived awful wounds without immediate medical treatment because these tiny soft things cleaned away the necrosis. We take the maggots for granted because what they eat disgusts us; it smells bad and it carries disease. But they transform it and make use of it, and then turn into entirely different beings with wings. Perhaps we don’t see them as noble creatures like we do the wolf, but perhaps we need the maggots at least as much.
“Down here, we all float”
Instead of decomposing normally, bodies buried in the tombs beneath the cathedral in Venzone, Italy were perfectly preserved and still recognizable even after many decades. Townspeople periodically retrieved and commune dwith their dead loved ones. In modern times, scientists finally traced the source of this wonder to Hypha tombicina, a microscopic, parasitic fungus that rapidly dehydrates the bodies before decomposition can even begin.
