This is the third year I have seen your tribute publications, time flies.
It's fascinating to see the importance that the number seven takes, in many people I know (I'm no exception, it's also my favourite number, but mostly because of my birthday), but also more generally, in Indo-European culture the number seven has a lot of symbolic baggage, like the 7 days of creation, the flower of life,...
It's as if our ancestors saw the geometric importance of this number and based their whole religion and philosophy on it, so much so that even today we keep an unconscious memory of it and like it "without knowing why" :)
Have an excellent year 2025, may the pain of the past strengthen you for tomorrow.
