My personal belief is that the better we answer this question — Does death truly kill us? — the better off we as an evolving planet will be.
This is a question that as a general rule science is not motivated to answer. However, there is an ever-increasing pile of anecdotal evidence that life goes on after death — that consciousness survives the demise of the body.
Some have opined that the reason why science doesn’t want to tackle this question is that the answer is not conducive to profits. Scientific research is most often funded when there is a profit to be made from the work. Ignorance is better for corporations because then they can sell products that play off the fear of death.
It would change the whole dynamics of fear to learn that Earth is not the chaotic mess it often appears to be. Rather, life here is an orderly Earth School curriculum where the point of our physical existence through a multiplicity of different lifetimes is to learn about love. Our bodies die off but our souls eventually slip into new bodies, new lives. It this were proven and commonly accepted, it would mess up the profit-making paradigms found in life insurance, health care, the war industry, the entertainment industry (war movies!) and a bunch of other things.
People who have had near-death, out-of-body, or other spiritually transformative experiences frequently lose their fear of death and radically change their lifestyle to one of love and compassion. It changes their whole outlook on life. They have something to tell us if we’ll drop our preconceptions and habituated thinking long enough to listen. These people are easy to find. They are not hidden in remote outposts of the Himalayas. They’re all over Facebook and YouTube.
We just need to start paying attention.
