There is no one in a body to know it is dead, you've established that so who is the entity that is in the body that knows that body is alive? that is suddenly not there anymore to know it is dead, who is this knower that knows it is alive but not dead? if this knower is alive how can that which knows it is alive also know it is dead? ...where does the knowing of aliveness come from ..if there is no knowing of death?
Can you not see that life and death are known concepts/knowledge that no body can know...they are illusions of knowledge.
Can the knower that knows it is alive but doesn't know it's dead even exist, how would the knower even know what aliveness is without knowing what it isn't?
How come there is a knower of life, but not a knower of death, what would being alive even mean to the knower? wouldn't that just mean that the only known knowledge is of life?
A thing is a concept known...can a concept know it is a concept, can that which is known know what is knowing that known?
