When our minds come home

Don't worry it's not the second interpretation, I dislike that one as well. All your interpretations are extremely interesting though. Actually I had something completely different in my head, though it's probably not clear. I tend to have whole sections inside of my poems that I can't seem to add without breaking a flow. If see it as an image, to hear, to understand, a lot more things to add come to mind. Snakes are supposed to be sin for humanity, but both snakes and the rest of the animals (beasts) return home with only the coming of darkness. There is no worry, guilt or hatred that returns with them. When a man is alone in the dark, he has to be with himself. This means all the sin and guilt he's invented follows him. Man is terrified to be alone. For when he is alone, he has to fight against what he feels are his sin. Without the invent of sin to haunt them the rest of the animals are free of this. They are also free to choose their actions without fear thus being truer to their nature. But I’m not trying to say all that (I’m not sure I can, poetically in any case), just trying to contrast the two. The fight is left unidentified but what do our sins do, or what we feel is our sins, except fight against us? I suppose what I'm trying to get at is if we didn't know of sin, it won't follow us like a shadow.
