Well, firstly, let's define death. What is it, an end to your vital signs, when your body no longer functions? What if your bdy works, but your mind does not, a la Terry Schiavo? Or is death more spiritual, someone might continue to life and make concious rational decisions, but what if something tragic happened, and emotionally, they feel nothing. Is that death? It all depends on your perspective, my friends. I tend to take the third view, that without emotional connections, no matter what you do, you are, in effect, dead. Because it is our connections to other people that allow us to actually experience life, instead of just live.
So yes, from that standpoint, I do believe in death. I've seen it happen, seen people who are spiritually and emotionally bereft of life. I believe in death.
At the same time, I do not. When the body stops functioning, I believe that the mind, the spirit continues in some way. I'm sixth-sense sensitive, and to those of you who don't believe in that, fine, but I have indeed seen ghosts, I know that in some way, spirits do inhabit our world. One of my best friends has been posessed. If there are other realms that other spirits inhabit, I wouldn't be surprised, but I do not know this for sure. So from that perspective, I do not believe in death, because life is more than just having an active body.
