You've lived this life before.

Imagine that everything you are experiencing right now, every tiny detail and every emotion, you have already experienced, identically, an infinite number of times. Not in another life, not in a parallel universe: this very day, this very room, this very conversation, already repeated endlessly. Nietzsche, the man who called himself the Antichrist and who proclaimed the death of God, at a certain point in his life had an insight so powerful that it changed him forever: everything returns, everything returns eternally. We are accustomed to thinking of Nietzsche as the philosopher furthest removed from mysticism, almost an opponent of the idea that there is something beyond appearances. Indeed, for him, reality is only what can be seen and touched; any mystical explanation that seeks a hidden meaning is, as he wrote, “not even superficial.” Yet, it was precisely Nietzsche who, while walking in the Swiss mountains near Lake Silvaplana, was struck by what he himself described as a thunderbolt: the idea of eternal recurrence. This is not the mysticism of those who seek God in the void, as did the mystics he despised; it is a complete mysticism that celebrates the beauty of every single moment. Nietzsche called it “amor fati”: learning to love one's destiny, seeing the necessity of everything as something beautiful, saying yes to everything, even to pain, even to bad things. During that walk, Nietzsche stopped near a pyramid-shaped boulder and felt this thought burst into his mind: every event, every person, every moment—everything will be repeated endlessly, identical in every detail. He recounted it in words that sound like a religious confession: “A thought flashes through me, with necessity, without hesitation; I have no choice… everything happens as if I were swept away by a storm of freedom and power.” The astonishing thing is that Nietzsche took this experience so seriously that he believed he could prove it scientifically and spent months searching for mathematical proof of eternal recurrence, only to realize that what he had experienced could not be explained by logic. It was an intuition that had changed him, and that was all. And he was not alone. His friend Resa von Schirnhofer recounted that, after whispering the secret of the eternal recurrence to her, Nietzsche seemed like a different person, almost possessed. In a letter to his friend Köselitz, he wrote: “The intensity of my feelings makes me tremble and laugh at the same time… I couldn’t leave the room… my tears were not of pity, but of jubilation.” This experience did not lead him to believe in God, but it gave him a new kind of mysticism: not the kind that denies the world, but the kind that makes it sacred, eternal, in every detail. From this arises the question that Nietzsche poses as a challenge: If you were to live this life, exactly the same, an infinite number of times—every joy, every sorrow, every small or great act—would you really want it? For Nietzsche, the idea of eternal recurrence is not just a philosophical curiosity: it is a spiritual test. Are you ready to say yes to everything in your life, so much so that you would want to repeat it endlessly? If so, then you have attained what he called the greatest joy, a kind of secular bliss. But if, on the other hand, it weighs on you, if you think there are some things you would never want to relive, then that question becomes an invitation to transform your life into a work that is worth reliving. Some philosophers have tried to reduce the eternal recurrence to a mere mental exercise, but they overlook the extent to which that epiphany profoundly affected Nietzsche and those close to him. His challenge is not, “What happens after death?” but, “Is your life, as it is, worth living forever?” Here lies the true reversal: you don't have to improve your life out of fear of the final judgment, but out of love for its repetition. Consider Barbara Ehrenreich, an activist and atheist, who recounted having had a mystical experience similar to Nietzsche’s in a small California town: an ecstasy that left her speechless, too powerful to ignore, but which never led her to believe in God. Even without religion, experiences like this change you. So, if you had to relive this day, would you really want it to be exactly the same? Or is there something you would change right away? Nietzsche’s true legacy is not an abstract doctrine, but a burning question: Are you ready to love everything that has happened to you, to the point of wishing for it to last for eternity? Living as if the answer were yes is the most radical challenge you can set for yourself. The takeaway sentence is this: live each day as if you had already chosen it for eternity.
