In 1950, the young son of Robert Marcus died of polio. Albert Einstein wrote this short metaphysical exposition to help him through the pain. Is it philosophically sound? I don't know. But when someone is mourning the loss of a child, that's not really important.

One does not necessarily need religion to achieve what Einstein was describing. Agnostic astrophysicist Neil DeGrasse Tyson explains a thought which he says for him, produces no greater spiritual experience:
"Recognise that the very molecules that make up your body - the atoms that construct the molecules, are tracable to the crucibles that were once in the centres of high mass stars, that exploded their chemically enriched guts into the galaxy, enriching pristine gas clouds with the chenistry of life. So that we're all connected, to the each other - biologically, to the Earth - chemically, and to the universe - atomically. That's kind of cool. That makes me smile, and I actually feel quite large at the end of that. It's not that we are better than the universe, we are a part of the universe. We are in the universe, and the universe is in us."
Besides, since they stopped allowing comments, Neatorama might be the only place one can discuss the letters.
What I do believe is that saying there is some sort of life after death is delusional.
As far as I'm concerned there is nothing after death.
If that is too harsh for you just accept that we don't know. Why is this so hard to deal with for some people? And it gives yourself the possibility to mourn instead of believing we go to heaven, in which case we should celebrate death instead.
I worked as a hospital chaplain one summer. One day, I was called upon to baptize a dead baby. Did it help the baby? No. But it helped the mother a lot.
