There is an assertion that spans the centuries, recurring in sacred texts as in physics treatises, in poets’ verses as in mystics’ meditations. Every time it is uttered, it leaves a mark.
It is an assertion that defies ordinary logic, overturns our mental habits, and forces us to look at reality with different eyes. It goes like this: everything is in everything. And immediately after, as if to emphasize that this is not an abstract idea but a concrete truth, it reiterates: it is equally true that everything is in everything. Twice, almost to say there is no escape, that it cannot be reduced to a metaphor, that it is a law of existence before it is a thought.
Those who truly understand this truth, the ancients tell us, have attained great knowledge. Not just any knowledge, not the accumulation of facts, nor mastery of a discipline. But that knowledge which transforms, which liberates, which allows one to see the world for what it truly is.
Let us pause for a moment and let this idea pierce our certainties. We are accustomed to thinking in terms of separation. This is me, that is the other. Here my body ends, there the world begins. Today is different from yesterday, this is different from that. The mind, to function, needs to distinguish, to classify, to bring order. And rightly so. But there is a deeper level, a layer preceding all distinctions, where separations reveal themselves for what they are: useful conventions, not ultimate realities. At that level, everything is in everything. Every thing contains every other thing. Every part reflects the whole. Every instant encompasses eternity.
Contemporary physics, with its extraordinary capacity to explore the invisible, has returned this truth to us in forms our ancestors could not have even imagined. Quantum theory tells us that elementary particles are not separate entities, but excitations of a single field permeating the entire universe. Two particles that were once in contact remain forever correlated, regardless of the distance separating them.
And this is not a metaphor: it has been measured, proven, it is a fact. Einstein called it “spooky action at a distance,” and for his entire life he could not accept it. But reality is greater than our theories. Reality is that everything is connected to everything, and that every part, however small, contains the whole in some way.
Biology tells us the same story, in a different language. Our body is an ecosystem of billions of cells, but also of billions of bacteria that inhabit us and without whom we could not survive. We are not isolated individuals; we are communities. And the community extends beyond the boundaries of the skin: trees breathe what we exhale, we breathe what they exhale.
We are made of the same matter as the stars, and when we die, that matter returns to become earth, water, air, nourishment for other lives. Nothing is created and nothing is destroyed. Everything transforms. And in this continuous transformation, every thing contains within itself the trace of all that has been and the germ of all that will be.
Philosophy, ever since its inception, has sought to express this intuition. Giordano Bruno, burned alive for his ideas, wrote that “everything is in everything, and in every part is the whole.” He explained that the universe is one, infinite, immobile, and that everything within it moves according to an order that is not external but internal.
There is no center, no periphery. Every point can be considered the center, because in every point the whole is reflected. It is a vision that is hallucinatory, if we look at it with the eyes of our habit of separation. But it is also a vision that liberates, because it dissolves the idea that something can be truly foreign, truly other, truly an enemy.
Eastern spiritual traditions have taken this intuition to levels of depth that the West is only now beginning to glimpse. Advaita Vedanta, the non-dual philosophy of India, teaches that Atman, the individual self, is identical to Brahman, the ultimate reality. Not similar, not a part, not a reflection: identical. The separation between me and the world is an illusion, a perceptual error that generates suffering. The path to liberation passes through the recognition of this unity. It is not a theory to believe in, but a truth to realize. When you realize it, everything changes. There is no longer an “I” to defend, no longer an “other” to fear, no longer an “outside” to protect oneself from. There is only the One, the indivisible, the Whole.
But what does all this mean for us, here, now, in our daily lives? It means we are never truly alone. It means that what we do to others, we do to ourselves, not in a metaphorical sense but in a literal one. It means that peace in the world cannot be separated from peace in the heart, and that war in the heart inevitably reflects itself in the world. It means that every action of ours, however small, propagates through the network of existence and reaches places and people we will never see. It means there is no outside and no inside, but a single field of experience in which everything is intimately, inextricably connected.
Understanding this is not an intellectual exercise. It is a radical transformation of the way of being in the world. When you understand that everything is in everything, you stop accumulating things as if they could fill a void that does not exist. You stop judging others as if they were separate from you. You stop fearing the future as if it were other than the present. You stop defending your borders as if they were real. And you begin to live differently. With more lightness, because you know that nothing essential can be lost. With more openness, because you know the other is yourself. With more courage, because you know your strength is not just yours.
The great mystics have always spoken of this truth. Meister Eckhart, the 14th-century German Dominican, wrote that “the eye with which I see God is the same eye with which God sees me.” Not two eyes, but one. Not two gazes, but one. The knowledge of God and the knowledge of oneself coincide, because ultimately there is no separation. And when this coincidence is realized, when the illusion of dualism falls away, what remains is peace. Not a peace dependent on circumstances, but the peace that is the very nature of reality.
Today, everything seems broken apart; divisions multiply and conflicts intensify. Perhaps we need to rediscover this truth more than ever. Not because it is a consolation, not because it makes us close our eyes to pain, but because it is the only perspective from which we can hope to build something different. If everything is in everything, then war is never just out there. It is also within. And peace cannot be just an agreement between powers. It must also be a movement in the soul.
He who truly understands this truth has attained great knowledge. It is not the knowledge of books, not the knowledge of formulas, not the knowledge that is put on display. It is the knowledge that saves, that heals, that liberates. It is the knowledge that makes one say: now I know. I don’t know what, I don’t know how, but I know. I know that everything is connected. I know that nothing is lost. I know that I am not alone. And in this knowing, which is not thought but presence, I find the strength to continue, to love, to hope.
Because if everything is in everything, then even the good I do today, however small, is already in the Whole. And it will not be lost. It cannot be lost. Because in the Whole, nothing is lost. Everything transforms. Everything lives.
Everything Is.
