"Oh yes, this eternal materialisation, this chance of a body, an opportunity. As I write this they report in the media that the population in Sweden has just become nine million bodies. Nine million bodies that come from where? From where? ? I remember that when my kids were big enough we could, in one way or another, communicate verbally. I used to ask them where they came from. ? Where do you come from? Do you know? Do you remember? I was wondering if they had some small reminiscences left, some small memories or so. They were still so close. So close to that incomprehensible. So close to that threshold just recently passed."
