Makes me think of that singular point at the beginning of the universe, before any matter existed, and from which everything we now know has sprung. Here we are as 'individuals', walking around, sharing atoms and ideas, most of which precede us by thousands if not millions of years. Maybe one day everything will be reunited :)
I like what you've done with the formatting in that last sentence - it really brings everything together to that single point, which of course reflects the sentiment of the poem itself. Nicely done!
Oh, Lazarus, the fact that you see such deep meaning in my words pleases me, for English is my second language (I started seriously learning it when I was 20 or so), and it takes a lot of thinking to not end up sounding like a five year old )))) ahaha, it might seem odd, but I worry a lot about my grammatical errors, feel the need to show my stuff to natives before posting.
I really aprecciate you seeing it deeper than just being about a personal tragedy!
