I'm pretty sure that the reporter who wrote the article misunderstood Ricky's words. I believe he probably said "astral body". In the simplest terms your "astral body" is just another word for your "soul". If you want to go deeper; there is a metaphysical contingent that would tell you that it's possible to travel outside the confines of your physical body, using your astral body. This is known as "astral projection".
All that said, and using a biblical reference, RW was probably just saying that his body is a temple and it's wrong to defile it.
