Where does it take us? I suppose it takes the "us" which is our consciousness, personality, and memories, and erases it. It takes the "us" which is the phyiscal elements which comprise our bodies and recycles them back through the environment.
All living things are born, they live, and then die. It's an observable cycle which indicates no existence, nor need, of any non-physically identifiable state beyond this cycle. The inherent, evolutionarily-developed, drive of life to survive has utimately expressed itself, in the consciousness of man, in the form of using the imagination to rationalize rejection of non-existence. This is a natural and understandable drive, but this obsession with the fear of dying, whether one is aware of it or suppresses it, is an unhealthy psychological state. Acceptance of the inevitability of one not existing, seems to be a freeing act, and when one examines the fear of death, one sees that not existing isn't really anything to fear at all.
