The why can literally be explained in thousands of ways. You have each religion and spiritual movement explaining the why in their own way. Then each human takes their own twist based on their religious or spiritual belief merged with their life experiences.
I do wonder if REM is truly the door to our spirituality, and not only just our subconscious mind. When you think about it, it is our subconscious that processes our conscious thoughts and actions to turn them into beliefs and our core moral and ethical structures.
Personally, I was both relieved and disappointed that I missed out on the NDE and OBE experience during my craniotomy in early 2011. Relieved because, hello, knocking on death's door. The tad of disappointment surprised me until I drilled into it (of course).
I'm not just a sci-fi geek, I'm a science geek and a bit of a spirituality geek. Having a near death experience would've been the ultimate of ultimates in merging both science and spirituality in a single adventure. Now that I think about it, maybe it was a good thing I didn't. With my curiosity, I would've gone towards the damn light and then where would we be, huh? Definitely not blogging about life after death today, that's for sure.
The argument will continue, there's no doubt about that, but beyond the experiences of a few, no one will ever know until our hearts actually stop, our brain nerves cease sparking and the docs can't bring us back.
I don't know about you all, but I'm not in a hurry to find out. So, what are your thoughts on the whole life after death thing?
