The eyes and body motif represents Yin and Yang. With Yin being the spiritual aspect while Yang being the physical. But like I said before, this is completely irrelevant when obtaining the Rinnegan because, like it has been stated, you just need to combine the sons' chakra. There was no mention, by Hagoromo nor Black Zetsu, about the eyes and the body components.
