Whitman's poem was sort of celebrating the human body. But it also (to me it seemed) rejected the existence of a 'soul'. That's why I sort of saw it as anti-religious.
Also, he wrote it at a time when religion considered the body to be dirty and something that should be hidden. Whitman seemed to be reacting to that by saying the body was beautiful and to be worshiped.. as opposed to focusing on saving our souls?
When the song mentions Venus and Mars, I think it's also doing something similar... admiring and devoting to the body (man and woman - venus, mars). When it mentions 'I shall embody the earth' it could be saying that when the singer dies, he doesn't go to heaven but rather becomes whole with the earth. In essence, it's saying there is no heaven but rather that our final destiny lies with becoming one with the physical world (rather than a supernatural world like heaven or hell). And that we should welcome, not fear, this lack of spiritual destiny.
Thoughts? Agree? Disagree?
The song is from the Movie 'Fame' btw.
