Einstein's theory that "Energy cannot be created or destroyed, it can only be changed from one form to another" and the way thought patterns are formed (electrical) has always kept me open minded to an afterlife.
Keep this in mind.
people toss around the word "energy" as if it means something more than it is. It's new age crap.
Sure, there's energy of some type that makes us who we are. Means nothing. Does a battery have any use once it's charge is done? That's energy too.
Even if you're right, it still wouldn't matter. An afterlife is pointless unless it can be demonstrated that it's you
that really exists. Since you are used to your body and your consciousness is an emergent property from your brain, whatever energy might exist after your physical body dies wouldn't be you in any real sense that would actually matter.
