I have questions about my body?

When the Buddha refused to be drawn into the net of these dogmatic views of existence and nonexistence, he had two things in mind: the ethical consequences of these two views, and the fact that the views of absolute existence and nonexistence do not correspond to the way things really are. The eternalists view this self as permanent and unchanging. When the body dies, this self will not die because the self is by nature unchanging. If that is the case, it does not matter what this body does: actions of the body will not affect the destiny of the self. This view is incompatible with moral responsibility because if the self is eternal and unchanging, it will not be affected by wholesome and unwholesome actions. Similarly, if the self were identical with the body and the self dies along with the body, then it does not matter what the body does. If you believe that existence ends at death, there will be no constraint upon action. But in a situation where things exist through interdependent origination, absolute existence and nonexistence are impossible.
