At death you cease to exist. But what is it that witnesses your non-existence, or, as it were, continues to assure your non-existence, places you in the correct column of the book of life and death? This is the background consciousness, the 'field' in which foundational logic can prevail, in which the yes can be separated from the no. Take that away and you are left with a void in which anything and everything is not only possible but must take place continuously and discontinuously. If the 'cost' of existence were reduced to zero then all forms of existence would explode in and into that void. Does this happen anywhere? How would you know one way or the other? But your view is certainly from a place where existence 'matters'.
