Hurray!!! I’m that 1% that understand .001% of Kegavna.
From what I understand, there’s a great deal of transitioning “Up There”, everything’s getting ready, waiting in anticipation for the Holy Shabbos… Then our holy nation takes on (enrobes in) the new Neshamah.. This is the time of the Service of Davening, to Bless (and Daven) with a happiness and gladness, with a beaming countenance.
It’s the last part I choose to put my focus on. So much upheaval, changing, cleaning.. all the heavenly spheres above. All so that a Jew come and Daven with happiness, a geshmake, zestful manner!!!
