I'll try to explain.There's a religious belief that all people are souls who are using a temporary biological body so that they can gain experience in the physical world.The sentences mean that you are such a soul that has a body in the physical world. You can't have anything what you are. According to that belief you can't say, "I have a soul" because you're a soul. You can only say,"I have a body, clothes, food and other things" because you aren't those things.

You haven't formed your question correctly. I understand it literally, but I don't know what it means.
