The body is only a combination of elements. It was not our body in the past and it will not be our body in the future. It will certainly not be our body after we die. Even at this moment, this body does not really belong to us. It is constantly changing, with new parts being manufactured from different things. Yet, a person can attach the idea of "self" to the body and consider it a permanent entity. This is an illusion. This is delusion.
