Cover art for Feathers  lyrics by A Perfect Circle

I think the meaning of this song is pretty clear; and I think that a couple of the existing comments have pretty much nailed it. I just wanted to address the one line that I think a lot of people are struggling with: "Onus fate and undue odium" I think if we simply add a comma after "Onus" and treat this line as a list of three things: "Onus, fate, and undue odium," it becomes more clear. Then the line can basically be translated to, "Onus (our burdens and responsibilities) fate (the way things will play out no matter our actions) and undue odium (undeserved and unfounded hatred). The next line is another list of four things: "Amour, anchor, led, and stone" MJK is simply listing things that we should, through communication, let go, let them become feathers.
