There are moments people struggle to put into words. Standing before the sea, or in the middle of a prayer, or just on an ordinary morning, and suddenly something opens. A sense that everything is connected, that there’s no real boundary between who you are and what surrounds you, that for a moment you understood something vast that has no words for it. It passes, and a strong impression stays behind that doesn’t fade for years.
What’s intriguing isn’t only that people have this experience. It’s that they describe it so similarly, everywhere, in every age. The same sense of unity, the same quality of being “more real than ordinary.” And that sets up a sharp question: does the moment reveal something real about the world, or only something about the brain having it?
What can honestly be said, and where to be careful
These experiences are real, documented, and some of them can even be brought on deliberately, through long meditation, through extreme states, sometimes through stimulating particular regions of the brain. Alter the brain’s activity and you can produce the sense of unity. That’s an important finding.
But here is exactly where the trap waits, and it’s a subtle one. The fact that an experience can be triggered from the brain doesn’t make it “only” a fabrication of the brain. Seeing a real tree also runs through brain activity, and no one concludes that the tree isn’t there. A mechanism is no proof of forgery. But the reverse holds just as firmly: the intensity of the experience, the sense that it’s more real than anything, is no evidence that what was experienced in it is real. A sense of certainty is a feeling, not testimony. You have to walk carefully between these two traps.
Where it leaps into philosophy
Suppose someone experiences a total unity of all things. What may they conclude from it? “I felt that everything is one” is excellent testimony about what they felt. It is not testimony that everything actually is one. The leap from “this is how I experienced it” to “this is how the world is” is exactly where you step off solid ground.
What can be said is at once modest and interesting. Experiences like this are a fact about human consciousness, and an impressive one. They show that the brain is capable of states in which the ordinary boundary between “I” and “world” goes soft. What that says about the world itself is already interpretation, not a finding. And that difference is worth keeping even when the experience is overwhelmingly convincing.
What tradition offers
The sense that there are states in which something deep beneath the everyday shows itself is old and shared by nearly every spiritual tradition. Christian, Sufi, Indian and Jewish mysticism each describe, in their own language, moments of the boundary dissolving and of nearness to something vast. In the Hebrew phrasing, Kabbalah speaks of “devekut” and of the self being nullified before the Infinite, and is very careful to frame these moments, to warn against them, and not to promise they reveal any truth. Not a scientific statement, and certainly not evidence about the structure of the universe. It’s another language entirely, perhaps feeling its way toward the same place we stood before: that the boundary between inside and outside isn’t as sealed as it usually feels. Whether that hints at something real, or only at a shared structure of the human mind, is yours to decide.
To close
Think back to that moment before the sea, or in the middle of the prayer, when for an instant everything looked like one. The impression it leaves is real. Whether it’s a touch of something beyond, or a property of your own brain, stays open, and even the person who has it most powerfully can’t settle the matter on the strength of its intensity alone.
Which leaves a question: if you can’t tell from the inside between an experience that reveals truth and one that only feels that way, what would you need in order to know the difference, and where could that even come from?
