I needed to cook the celery ( already cut into cubes ) first.
After like 10 minutes of boiling them, I realized that there is a beautifully ethereal, coconut-milky scent that is coming from my kitchen.
The scent with an instant calming effect took slowly over my apartment. It was tenderly sweet, not too sugary, with hints of sandalwood, enveloping me into a wonderful feeling of full peace and comfort. After a while, I wasn't smelling the celery aspect anymore, only a bit of earthy-ness reminded me of that perhaps, and I was back to my childhood.
I know I am not supposed to remember those times when I was still breast fed, but I directly had this scent associated with my Mother. Without any specific memory, I felt this amazing fullness, being in safe, being taken care of, nurtured, protected.
So either cooking celery made me unconsciously remember me of the times of being breast fed, or there was an angel passing by in Grasse.
