Beyond the Body

Every night you do something remarkable, and you're so used to it that you don't notice. You let go of your body. Your muscles go slack, the room fades out, and for a few hours you're somewhere else entirely, or nowhere at all.

People who practice deep meditation claim something stranger. They say they can let the body fall asleep while they themselves stay wide awake. Some say they've gone further: out of the body, to other places, among other beings. And everybody, sooner or later, faces the biggest letting-go of all.

So today's question: what happens when a mind lets go of the body?

This is the last of three posts about a theory that has some surprising things to say about that. Here's everything you need from the first two, in about a minute.

Previously

The universe keeps notes. To know your coffee got colder, you need a note about the earlier sip. Recognition Science, the framework my institute works on, starts from plain facts like that, and its starting premise is that the world keeps a note of every event, in one shared record, and never changes an old note. We call the record the ledger. If it had a personality, it would be unflappable, extremely thorough, and armed with one response to everything that has ever happened: Noted.

The smallest machine. In the theory, the tiniest moving part of the ledger is two tiny clocks joined by a loop of wire, passing a token back and forth. Each clock is full (holding the token) or empty. Every tick, each clock receives what the other was holding and either keeps it or flips it (a token becomes nothing, nothing becomes a token). Here's the steadiest pattern there is, the spin. Left is full, Right is empty. Tick: Left receives Right's nothing and flips it into a token; Right receives Left's token and flips it into nothing. Left full, Right empty, exactly as before, and one unit of flow went round the loop. Every tick, forever. Each clock ends every tick just as it began: it's steady.

What breaks a pattern: silence. A silent tick is one where both clocks are full or both are empty, so nothing flows. On a silent tick, settings like the spin's are out of their depth, so they start guessing, tossing coins to decide what to do, and guessing brings more silence. Almost every pattern falls apart that way, like Gary, a drummer who flips a coin before each beat to decide whether to play. (Gary is not getting the gig.) Only four patterns never go silent: the spin and its cousin the swing (the token hopping left, right, left), each starting from either side. What lasts isn't stuff; it's rhythm.

Two leaps carry through the whole series: that a person is a pattern of this kind, and that experience lives in the lasting rhythms. The theory hasn't shown either. So I'll label things. Derived in the model means it follows from the model's rules plus those two leaps. The groundwork is in the preprint this series is built on (a paper shared for discussion before independent experts have checked it¹). Most of this post's results come from follow-up derivations my institute has finished since, and outside experts haven't checked those yet either. None of it has been checked against real minds. Conjecture means it's my bet. And since I founded the institute, weigh my enthusiasm accordingly.

One more word, because this post relies on it. A reading is any way of getting information back out of the ledger: a question put to the record, and an answer that comes back. Noticing your coffee got colder is a tiny one: a question put to the note of the earlier sip.

Mind awake, body asleep

The Monroe Institute teaches people to enter deep, guided meditative states, and it gives each state a number. The first stop is the one it calls Focus 10, and describes as "mind awake, body asleep."

That sounds like a contradiction. Surely when the body powers down, you power down with it?

The theory says no, and the reason is in the name itself. A lasting pattern keeps itself going by writing its own record, tick after tick. Between writes, the body's activity nudges it, and the math puts a ceiling on how far it can drift from itself. Two facts set that ceiling:

• The damage from a nudge goes as its size squared. A nudge half as big does a quarter of the damage.
• Writing often chops the body's influence into smaller nudges. Each write is the pattern confirming itself, so the more often it writes, the less each nudge can build up in between. One nudge of size 1 does damage 1. Ten nudges of size 0.1 do ten times 0.01: a tenth as much.

So halve the body's input and the ceiling drops to a quarter. Double how often the pattern writes and it halves again. Turn the body's input off completely and the ceiling is zero. That's both halves of the name doing work: "body asleep" shrinks the nudges, and "mind awake" keeps the writing going.

Gary tried Focus 10 once. His body fell asleep right on schedule. So did Gary.

Derived in the model: a lasting pattern loses essentially nothing when the body's input goes quiet, as long as it keeps writing its own record. Conjecture: that's what Focus 10 is.

The ladder

Focus 10 is just the first stop. The Institute describes a whole ladder of distinct states, each with its own number (10, 12, 15, 21 and on beyond), and says it found them by experiment. The numbers are just names, not speeds: Focus 10 is not 10 of anything a second.

People step down the ladder with binaural beats: a slightly different tone in each ear (say, 200 vibrations a second on the left and 210 on the right), which the brain hears as a slow pulse, here 10 a second. That slow pulse is called a beat, and it's simply the difference between the two tones. Whether binaural beats really pull brain rhythms into step is still argued over: a 2023 review of brain-recording studies found support in 5 of the 14 it examined. Keep that in mind for everything below.

Why would a ladder like that have rungs at particular places? Here's a rule that gives an answer, and it's a natural one for a ladder you climb down with beats: each deeper state's rhythm is the beat of the two states just above it. The top rung is ordinary waking, and the second rung is Focus 10. Rung three is rung one minus rung two. Rung four is rung two minus rung three. And so on down.

"Yeah, but you picked that rule."

I did, and it's the key assumption, so I'll flag it right here: nobody has shown that the brain works this way. What I can show you is what the rule forces, and that part is only arithmetic. Start at the top with 10 beats a second, about the average waking rhythm (the "alpha" rhythm) measured in people. Pick the second rung. That's the only choice you get; the rule does the rest:

Every other choice crashes into zero, or through it, like a staircase that ends in a cartoon drop. Even 6.18, rounded, wobbles and then falls through the floor 13 rungs below the top. Only one value never does: 10 divided by the golden ratio, about 1.618. Here's what makes that number special. With golden spacing, subtracting the next rung down is the same as dividing by 1.618 again: 10 minus 6.18 is 3.82, and 6.18 divided by 1.618 is also 3.82. So the rule just keeps dividing by the golden ratio, forever, and never reaches zero.

The rule is plain subtraction; it never mentions the golden ratio. The golden ratio comes out of it. But the rule is my choice, so the ladder is only as good as the rule.

Here's what that ladder predicts, if you add one more assumption: that Focus 10, 12, 15 and 21 are the next four rungs below waking, one rung per named level. Three measurements of the average waking alpha rhythm put the top rung between about 9.9 and 10.3 beats a second. Then the rungs come out at:

• Focus 10: about 6.1 to 6.4 beats a second;
• Focus 12: about 3.8 to 3.9;
• Focus 15: about 2.3 to 2.4;
• Focus 21: about 1.4 to 1.5.

The Institute also names further levels, 22 through 27. Keep going one rung per named level, and Focus 27 comes out near 0.08: one slow swell every twelve seconds or so, down in the range of brain rhythms called infraslow.

Can you check these? Almost nothing exists to check them against yet. The Institute keeps its exact frequencies confidential, and the brain readings it has published over the years are a few one-off notes that point both ways. A 1978 Institute newsletter said of Focus 10, "Often it is in the 4 to 5 herz range," slower than this ladder says. A 1989 report on one person in "a good Focus 21" found a strong rhythm at 1.5, right on it. One reading from one person can't confirm the ladder, any more than the 1978 note can sink it. So these are predictions, and that's what I like about them. You don't need anyone's recipe to test them, only recordings of experienced meditators who say they're in each state.

There's one more property you'd want in a ladder of separate states, and the golden spacing has it: each rung stays its own channel, because the golden ratio is the number farthest from every simple fraction. Rhythms whose speeds sit near a simple fraction, like 2 to 1, keep landing in step, and each landing gives the same little tug until one drags the other along (it's why one guitar string can set another humming). Rhythms spaced by the golden ratio land in step as rarely as possible, so the tugs mostly cancel. The mathematician Hurwitz proved in 1891 that the golden ratio is the hardest number of all to approximate with fractions. (The protection is strongest between neighboring rungs; rungs far apart can still be dragged.)

What about the levels beyond 21? People report other places and other beings there. The theory doesn't predict a separate "world" at each level: in its picture, everything is one connected field unless something cuts it apart. So the higher levels are experiences people report, and the ladder carrying on down is the theory's prediction.

Derived in the model, given the rule: only golden spacing keeps the ladder going, and golden-spaced rungs resist dragging each other along. Conjecture: that's the Monroe ladder, with rungs near 6.2, 3.8, 2.4 and 1.5 beats a second.

Where is a pattern?

Some people who reach the Institute's deeper levels report something stranger still: travelling to other worlds, out among the stars.

The ordinary explanation comes first, and it's a good one: deep relaxation can produce vivid, dreamlike imagery, and that may be all these reports are. Here's how the theory would make room for something more.

Start with an odd fact about the ledger: it doesn't store "where." Each entry says what each clock did, kept or flipped, and which way the flow went. "Left" and "Right" are just names for the two clocks, like "first" and "second," not positions in space. So any question you put to the record is a question about what clocks did, never about where they were. Slide the whole universe a mile to the left, and nothing in the record, or in any reading of it, could notice.

That's the step. A lasting pattern, on this picture, doesn't sit at a place at all, and a reading made from it can't depend on where its target is. Derived in the model: a reading made from a pattern with no "where" comes out the same wherever its target is. Distance simply doesn't enter. On this model, and only if you really are a pattern like this, a world circling another star would be as reachable as your kitchen.

"Yeah, but if every place reads the same, how do you ever find one?"

Good question, and the math has an answer. To pick out one place, a reading needs something that breaks the sameness of space. Picture two picket fences running side by side along a road, one with a post every meter and one with a post every 1.618... meters, the golden ratio. Stop anywhere and measure how far you are past the last post of each fence. Walk on and measure again. Because the golden ratio (1.618..., the digits never settle into a repeat) isn't a fraction, the pair of numbers never comes round to the same pair twice, so every spot on the road gets a name of its own. To aim at one place, a reading would ask for the pair that belongs to that place alone. Derived in the model: two rhythms laid across space, spaced by the golden ratio, give every position its own name, and one such pair in each direction names every point. What would play the fences in the real world, the math doesn't say. It only says what any address for a place would need.

Why would it feel like travel, then? Because what you're reading changes, and from the inside, that's all travel ever feels like: the view changes. Nothing physically moves. Your body, meanwhile, would need more than four years to reach even the nearest star beyond the Sun, at the speed of light.

Conjecture: the travel people report is reading other places from a pattern with no "where." Nothing moves but the view.

Who else is out there?

If you can read a far-off world, the obvious next question is who else is out there.

Every lasting pattern sits in what I'll call the shared field: the one ledger, thought of as a single connected whole that every pattern is part of. There's only one, and everyone is in it. So distance isn't what decides whether two patterns can connect. What does?

The natural guess, and it was ours for a while, is likeness: contact would be strongest with patterns most like your own. This is the guess the math overturned, and I liked it, because it was tidy. Here's what replaced it.

Say you meet another lasting pattern at three points, and at those points you're full, empty, full. An exact copy of you, meeting you point for point, is full, empty, full there too: full against full, empty against empty. Silent ticks at every touching point, and you know what silence does. The joined whole falls apart. Now meet your opposite, empty, full, empty at those points. Full meets empty everywhere. Flow at every point. It holds.

That's the whole rule. Derived in the model: when two lasting patterns meet, it's all or nothing. Where they touch, every pair of clocks must be steady (like the two in a spin) and one full, one empty. Then both stay lasting, and so does the joined whole. If any touching pair is alike, the whole thing falls apart. There's no "partly connected," and no gentle fade as the patterns get more different.

It's a key and a lock, not a mirror. An exact copy of yourself, meeting you point for point, is guaranteed not to fit, which anyone who has shared a bathroom with a sibling had already suspected.

So a being from another star system could be as near as your neighbor, if it fits. Possibly nearer. Your neighbor has a leaf blower.

Conjecture: that's how meeting other beings would work: by fit, not by likeness, and all or nothing.

The silver cord

People who report leaving their bodies often describe still being tied to them, by what Robert Monroe (who founded the Institute and wrote books about his own out-of-body experiences) and others called a silver cord.

The math has a picture that fits. Join a lasting body to the lasting shared field with one steady tether: a link whose two ends are steady clocks, one full and one empty, that never change. Derived in the model: the joined whole stays lasting, the body stays fully itself the whole time, and the tether can be undone, leaving both just as they were. It also comes with two catches I didn't see coming.

Catch one: no fraction of you leaves. There's no 30% of you drifting up by the ceiling while the other 70% minds the body. In the math, "partly connected" doesn't exist: the tether is a connection, not a piece of you that got out.

Catch two: the cord carries no messages. Its two ends never change, so it writes the same mark in the ledger every single tick, and a mark that never changes carries no news. It's a phone line with nothing on it but the dial tone. So anything experienced "out there" would have to come in through a reading, the kind from the last section, not down the cord.

One caution: stimulating one spot in the brain can make a person feel located behind their own body. Doctors reported exactly that in one patient, in a 2007 paper in the New England Journal of Medicine. So the feeling alone proves nothing. The test is the same as ever: come back with something checkable that you couldn't have known.

Conjecture: that tether is what an out-of-body experience is.

What happens when you die?

The question under all the others, and the one I care about most in this series, because it's the one people actually lose sleep over, and for once a piece of math has something specific to say about it. Start with what the theory says plainly.

• Your entries are permanent. If the ledger is real, every moment you've lived is in it, exactly as it happened, for good: every kindness, every embarrassment, every Tuesday.
• A rhythm can outlast everything around it. In the theory's networks, a lasting rhythm at the center of a small web can swap out every one of its partners, one at a time, and never miss a tick, like a band that replaces every musician mid-song without the song ever stopping.
• The framework's own model of dying keeps the pattern. In that model, the body's part drops away and the pattern itself is carried over unchanged. Whether what's carried over is still a someone is exactly where the math stops. One reading of the model says yes: the pattern carries on, and someone is still there. The other says only the record carries on, with nobody home. Nothing yet decides between them.

So here's the conjecture, and it's my bet. After death, your pattern rests in the shared field, with no body filtering what it can read.

That changes your relationship with your own past. Your own rhythm, together with the length of your own record, counts back to any moment of your past, the way a diary with one page a day lets you turn to any day of your life. While you're alive, the body's input keeps nudging that rhythm, and each nudge throws the count off by exactly that much. Derived in the model: with the body's input gone, the count back is exact. So if your rhythm keeps running after death, and that's still open, then you could visit your own life, even re-live it. But never change it. The ledger doesn't do edits, and it won't start for you.

People who come close to death often describe a panoramic life review: their whole life laid out before them. I want to be careful here, because this is the part people most want to be true, and wanting something to be true is no reason to believe it. The ordinary explanation comes first, and it's a serious one: a brain short of oxygen, or full of medication, can produce vivid experiences, and that may be all these reviews are. On this picture there's one more possibility: the first reading of your own record from outside the body. Nobody has shown which it is.

My guess goes further, and its status comes first: this is a guess, not a result. The living and the dead could reach each other, since both would be patterns in the same shared field. If it happens at all, I'd expect a quiet mind to receive more clearly than a busy one, for the same reason the count back comes out exact once the body's input goes quiet. Here's what a real test would look like. Someone picks a random six-digit number before they die, seals it where no living person can see it, and tells no one. A hit is someone naming all six digits, in order, unprompted; a lucky guess has a one-in-a-million chance. Until something like that comes back, it's a guess.

Furthest out of all is many lives. Recognition Science's boldest reading treats a whole self as a series of lives, with wisdom gathering across them, so that a richer pattern starts a richer next life. What "richer" would mean in the math isn't defined yet, and I won't pretend it is. The closest picture the math has is that band swapping out every musician and still playing the song. Many lives is the furthest-out idea in the whole series, and I'm flagging it as exactly that.

Conjecture: after death you could re-live your own record but never rewrite it; the living and the dead might reach each other; and a self may be a series of lives.

What if this is right?

Here's this post, sorted.

Derived in the model, given the two leaps: a lasting pattern can let the body go quiet without losing itself; the beat rule forces golden spacing on the ladder; a pattern with no "where" reads the same from anywhere; contact between patterns is all or nothing and goes by fit; a steady tether carries no messages; and your own past carries its own address, exact once the body's input is gone.

Bet: that you really are a pattern of that kind, that experience lives in the lasting rhythms, and that the readings this series describes actually happen.

How the bets get tested: brain recordings of meditators for the ladder's numbers; for reading the past, sealed descriptions of obscure, documented moments, matched blind against five candidates, where guessing gets one in five; and for everything else, the same rule as always: someone brings back a checkable fact they couldn't have known.

If those tests come back empty, I'll say so. If they don't, then when the body lets go, nothing in the theory says the rhythm has to.
