Birth. A powerful threshold experience resulting in a deep and profound impression. Seems even deeper considering the relative dearth of other impressions at that moment.
That first scream, the result of millions of completely alien signals shredding the nervous system to pieces and then rapidly reassembling it.
How much do we 'know' prior to birth?
Have we already cut pain or pleasure or some other deep canal into our brains by then? It's hard to imagine any other first binary. Perhaps our birth itself creates the binary and in that moment the first hard chiselling is made.
Run towards this, run away from that, stay in the middle.
Doomed to walk in that first deep wound forever, any way.
Can an impression this deep ever truly wear off or wear out or grow out?
What happens when this impression does wear off or wear out or grow out or when we manage to transcend it?
