Just a cool image

Like I said in my about me, not everything on here is gonna be deep and spiritual; this is one of those times :). I was surfing my deviantART today and found this image. It's an interesting concept and expertly done. If I'm honest, I really don't know what it means. I know that Seven is the perfect number, but I don't really get this piece. Any ideas?
