Request for explanation on heart sutta

This what I read part of heart sutta states; So, in emptiness, there is no body, no feeling, no thought, no will, no consciousness. There are no eyes, no ears, no nose, no tongue, no body, no mind. There is no seeing, no hearing, no smelling, no tasting, no touching, no imagining. There is nothing seen, nor heard, nor smelled, nor tasted, nor touched, nor imagined. apparently it is about the death of being to me.Also this description perfectly match and experience in coma or unconsciousness state of an individual. can I get proper and profound explanation for above?
