Today Gabriel and Noah lost their most loved Great Grand Father in this whole world. I have never looked up and admired a man so much as HRH Grand Duc Jean. He welcomed me with open arms, he always made me feel incredibly loved and welcomed, we shared incredible moments together, laught a lot, talked a lot with each other, I loved him so much! Rest in Peace Monseigneur. I will always hold you close in my heart and profound memories❣ Luxembourg and the world lost an incredible leader- one we can and should all aspire too. “When great trees fall, rocks on distant hills shudder, lions hunker down in tall grasses, and even elephants lumber after safety. When great trees fall in forests, small things recoil into silence, their senses eroded beyond fear. When great souls die, the air around us becomes light, rare, sterile. We breathe, briefly. Our eyes, briefly, see with a hurtful clarity. Our memory, suddenly sharpened, examines, gnaws on kind words unsaid, promised walks never taken. Great souls die and our reality, bound to them, takes leave of us. Our souls, dependent upon their nurture, now shrink, wizened. Our minds, formed and informed by their radiance, fall away. [...] And when great souls die, after a period peace blooms, slowly and always irregularly. Spaces fill with a kind of soothing electric vibration. Our senses, restored, never to be the same, whisper to us. They existed. They existed. We can be. Be and be better. For they existed (By maya-angelou)

"His role was indispensable in transitioning a people from the throes of identity annihilation, to the Grand Duchy his mother Grand Duchess Charlotte valiantly fought to preserve. His was no easy task following in the footsteps of such a larger than life historical leader in a place so decimated by war and challenged by bigger powers all around. But, he did it. Without him, the Grand Duchy of Luxembourg would not exist as it does today - thriving, expanding, and standing on its own as one of the most influential nations in the world.

With the people of the Grand Duchy, we mourn his passing, celebrate his life, and pray for comfort for his family and country he loved so much."
