Do we really have to be so extreme and say that we are either only the material body or only a sublime being - can't we say that we are both?
Most people live as if we are both, even though they may be either skeletonists or sublimists, because just as the sublimists cannot avoid the material body as long as they are living in it, the skeletonists cannot avoid at least the notion of an individual self in the classical sense, especially when it comes to ethics and love. However, we cannot overlook the fact that skeletonism and sublimism exclude each other. Either we survive death; then we are not the material body, or we don't, and then we are not a sublime being. Hence according to logical reasoning, although we are now in a combination, ultimately we cannot be both; we are either the material body, a sublime being beyond it. However, this does not mean that if we are a sublime being, we cannot possess a body, because there is the possibility of a sublime body.
If we are not the material body, why do we identify so much with it, and why do we feel pleasure and pain when the body feels pleasure and pain?
This is because our self identifies very strongly with the material body and its designations (the factor responsible for such an identification varies in different wisdom traditions). If this identification is overcome, for example during dreaming, we can easily dream of being inside a bird's body and flying high above the earth. When some parts of our body are under local anesthesia, the material sensual connection to those parts are lost, and we don't feel pleasure and pain of these parts anymore, although we are not less the same person as before anesthesia.
