Three images, printed one after another in a single paragraph. The spiritual path is one river with many feeder streams. There are many paths up the mountain, but from the peak you can see only one moon. The cows have many different colours, but the milk is the same.1
Read quickly they sound like the thing you say at an interfaith dinner. Read slowly, all three make one specific and fairly aggressive claim: the differences between traditions are inessential. Not minor, not secondary — not part of the essence, and removable without losing anything.
One word does the whole thing, and it's the one this page is named for:
Due to the dust of ages and the various coatings assumed by cultures and races, the vast majority of people may have lost insight into these true principles… On the surface, it's therefore only the dogma coatings that seem to separate the world's religions.1
A coating goes onto something that already existed. It protects, it obscures, and it comes off.
And unusually, the thing under the coating gets named rather than gestured at. Search every tradition and you'll find the same emptiness principles of spiritual practice turning up again and again, with the same results.1 So the milk isn't a vague shared spirituality. It's a specific claim: that every working method somewhere involves letting go of what's held, and that everything else is local weather.
Underneath the imagery it comes out narrower, and plainer:
Different religions simply advocate different sets of spiritual exercises or routines for arriving at the same states of attainment.2
That's about methods and results, not about doctrines. It doesn't require that anybody's beliefs mean the same thing. It requires that the exercises land in the same places — something somebody could go and check.
There's a qualifier attached that most summaries drop, and it's what keeps the thesis from going soft. The possibility of genuine progress is shared by all genuine paths — but the best and highest results only come to people who practise correctly, guide themselves by correct principles, and work hard enough to get high enough.2 So the traditions aren't being called equal in outcome. They're being called equally capable, with the outcome tracking what the practitioner does.
Then the payload, and it's about people rather than propositions. A Christian priest, a Jewish rabbi, a Buddhist monk, a Hindu yogi, a Tibetan master and a Sufi adept are all capable of reaching similar states — and when that happens these individuals are equivalent.3 Not the traditions. The practitioners, at the point of equal attainment, whichever door they came in by. Each tradition is qualified to produce a hero, if it starts emphasising cultivation practice.3
The shared destination gets defined once, in a single sentence, and it's worth having in plain form because everything else hangs on it. Spiritual evolution is a process of self-transcendence — and transcending the self means going past the limiting idea of being a body, an ego, a personality, a soul, a spirit or a self at all, in order to reach the state called spiritual self-realisation, or illumination.2
Look at what's on that list of things to go beyond. Body and ego and personality are the ones you'd expect. Soul and spirit are on it too, which is the part that surprises people who came in through a Western tradition. What's said isn't that you shed the coarse layers and arrive at the fine one you always suspected was really you. It's that the fine one is on the list as well.
Which explains why the comparison is made on states rather than on beliefs. A tradition's doctrine of the soul is exactly the kind of thing being described as a coating — and the target is defined as being past whatever that doctrine names.
The instruction that follows is quoted rather than argued, and it comes from Ibn al-Arabi:
Do not attach yourself to any particular creed exclusively, so that you may disbelieve all the rest; otherwise you will lose much good, nay, you will fail to recognize the real truth of the matter. God, the omnipresent and omnipotent, is not limited by any one creed, for, he says, "Wheresoever ye turn, there is the face of al-Lah."4
Two costs are named for exclusivity and they're different from each other. The first is that you lose much good — practical, and it means the useful methods sitting in the other traditions are unavailable to you as long as you're committed to their being wrong. The second is sharper: you'll fail to recognise the real truth of the matter, so exclusivity doesn't just cost you tools, it damages your ability to see what's in front of you.
It's an instruction about how to hold your own commitment rather than an instruction to give it up. Nothing there says leave your creed. It says don't hold it in the particular way that requires everyone else to be mistaken.
Then the register shifts without warning into something that sounds like a competitive-analysis brief, addressed to religions.
How can we make our own spiritual practice more efficient and effective for the task of abandoning ego-clinging, and for climbing the ranks of spiritual attainment? In terms of benchmarking, what is best from another school that we can borrow and use to our benefit? Which school seems to achieve results more quickly, and why? Can we borrow any of these practices and make them our own? If so, which ones and how should we proceed? How can we update our transmission to keep it in tune with the needs of the time, or even reveal whichever of these principles are already in our framework but have lost the light of day due to the ravages of time?5
Which school achieves results more quickly, and why. That's the question a firm asks about a rival's operations, and it's being put to the leadership of religions. The borrowing is defended as legitimate, and the defence is historical rather than theoretical. Taking methods from competing traditions has always been done, as standard practice, and because it's a sign of progress it should keep happening whether the motive behind it is pure or not.6 So nobody's motives have to be good for it to run. It expects them to be bad — competitive pressure, adherents, prestige, money — and says the borrowing is worth having anyway.
The last question in the list is the one that isn't acquisition at all. Reveal whichever of these principles are already in our framework but have lost the light of day. That's an internal audit: go and find what your own tradition already owns and stopped using. And it quietly assumes something the metaphors deny — that traditions contain genuinely different things, some of which have been mislaid. If it were all one milk there'd be nothing distinctive to go looking for.
A second volume supplies the documentary evidence this claim needs. It comes as four instructions from traditions with no contact between them. A Byzantine Christian is told to sit in his cell, collect his mind, lead it along the path of the breath into the heart, and keep it there.10 Then give it the prayer Lord Jesus Christ, Son of God, have mercy upon me, never to be abandoned.10 Breath, an anchor in the body, a repeated phrase.
A Sufi instruction runs the same shape and adds the endpoint. Sit alone, let nothing but God enter your mind, and say Allah, Allah continuously.11 Keep going until the motion of your tongue ceases and the word seems to flow from it. Then until all trace of motion is gone and the thought persists in the heart. Then until the form of the word, its letters and shape, is removed from the heart and only the idea remains, clinging to it.11 That's the recitation running down into stillness, described from inside by somebody who'd done it.
Then two descriptions of what arrives. John of St Thomas writes about the fire: it goes before Him and He is the fire, and it brings pain but does not torment.12 The fire which is God Himself consumes without causing suffering, and burns pleasantly.12 Saint Teresa describes the orison of union. The soul is fully awake as regards God and wholly asleep as regards the world, deprived of every feeling, unable to think of any single thing.13 Then: I do not even know whether in this state she has enough life left to breathe.13
Keep that last clause. A sixteenth-century Spanish nun, with no access to any Eastern vocabulary, naming breath cessation as the marker of the deepest state she reached.
One school gets held up as a guiding light, and the reason is that it advocates no fixed dharma at all.7 Zen isn't a form school, so its practitioners have rarely made extensive records of the phenomena that show up along the way. They don't merely neglect them — they dismiss them, and three reasons get given. The phenomena are ancillary. They detract from achievement on the path. And they're destined to leave anyway, because they belong to the realm of birth and death.7 A student who sets their mind on the final target goes straight at it, discriminating nothing and caring for nothing, and that is credited with the school's historically high proportion of masters who reached full self-realisation.7 Too much dogma in the way becomes an impediment rather than a help.
What they did record is a good picture of the whole attitude. Only the higher stages, and usually in a few lines of simple, suggestive poetry.7 The school describes itself as the special transmission outside the scriptures, which doesn't rely on words or letters, which directly points at the true essence of mind.7
Then the fault, aimed squarely at the school being praised. Ignoring the phenomena is one thing; understanding them is another, and this purposeful ignorance is a real defect in many Zen practitioners.7 Some of them think they've understood all the important matters — including the phenomena themselves — without having attained any real comprehension at all.7
And the reconciliation, which is printed right there and is easy to miss. You can certainly dismiss the phenomena, and you should — but it helps your ability to dismiss them if you know what they actually entail.7 Balanced immediately by the opposite danger: it would be foolish to spend years studying this without ever getting round to sitting down, and a large majority of people fall into exactly that trap.7 Then the line that closes it: you can never understand this material unless you cultivate to match the states themselves, and only then does their meaning become clear.7
The position holds, and it holds on a narrow ridge. Study enough to recognise what you're looking at, so that dismissing it is a decision rather than an accident. Don't study instead of practising. And accept that the reading only ever becomes intelligible from inside the practice, which means the book you're holding can't do the job on its own.
Here's the question the imagery makes hard to ask. All three pictures have the same shape: an invariant core, a variable surface, and the assumption that stripping the surface leaves the core intact. Streams have different beds and it's one river. Paths have different gradients and it's one moon. Cows have different colours and it's the same milk. A coating can't be part of what it coats — that's what makes it a coating.
So inside that picture, a difference between two traditions cannot be said to matter. Take the dhikr instruction and a Hindu mantra practice: procedurally they're close, and the Sufi version marks a boundary with no obvious Eastern counterpart — so far, all is dependent on his will and choice; but to bring the mercy of God does not stand in his will or choice.8 A practice with a point past which your effort stops mattering and someone else has to act is not obviously the same practice as one where effort runs the whole way.
That difference might be a coating. It might be the milk. Nothing in the three images can represent the question, and the question is the most interesting one comparative work has.
The benchmarking programme needs the answer to go the other way from the metaphors, too. You can only borrow from a school that has something you haven't got, and you can only ask which school gets results faster if the schools differ in ways that produce different rates. A programme built on real differences is being carried by imagery built on their absence.
You practise one thing, you've started reading about another, and you're trying to work out whether to bring anything across. Don't ask whether they're really the same. That question has no answer you can act on, and you'll spend a year on it.
Ask instead what the other tradition's instructions forbid that yours doesn't. Sit down with both sets and write out just the prohibitions, plainly, in two columns. Mine says don't guide the energy. Theirs says don't practise after eating, or don't do this without a teacher in the room, or don't carry on past six weeks if nothing has moved.
Prohibitions are the useful comparison surface, because nobody forbids something that wasn't a live failure. A tradition's list of don'ts is an accident report, accumulated over however many centuries it's been running, and it tells you what went wrong for people built roughly like you. Positive instructions converge easily — everyone says sit still and pay attention, because there aren't many ways to say it. The don'ts diverge, and where they diverge you're looking at genuinely different terrain.
Then borrow, and take the prohibition before you take the technique. If you're going to import somebody else's practice, import their warnings first, because the warnings are the part they paid for.
Two more things before you decide. Run the internal audit first — go through your own tradition for a principle it holds and no longer uses, because the cheapest borrowing is from yourself.5 And hold the whole comparison the way Ibn al-Arabi says to hold a creed: not by deciding your own is wrong, but by stopping short of needing everyone else's to be.4
Give it a season before you judge whether anything survived the transfer.
Ranges read: pp. 197–200. Nothing here is claimed about material outside them. [POPULAR SOURCE]. The Ibn al-Arabi passage arrives via Karen Armstrong's A History of God, a popular history and the third citation to it in the book.4 🚩 The line justifying the whole programme — that gong-fu is the easiest thing to see materialistically, to measure and to reproduce9 — is not supported anywhere in the book: nothing in six hundred pages is measured, and reproducibility is denied elsewhere on grounds of sex, age, health, past-life inheritance and even the location of the practice. [LOW CONFIDENCE] on all three halves of that sentence. Recorded and not carried: a national- and racial-character generalisation on p. 197, of a kind that recurs in this source and is excluded each time.2
The tension the source leaves standing is between the imagery and its own best observation. Three pictures assert that difference is surface. The Zen passage on the next page describes a difference — record the phenomena or dismiss them — that produces a higher realisation rate on one side and a specific characteristic blindness on the other.7 A design decision with consequences at both ends isn't a coating.
A second sits inside the practical advice, and unlike the first it is reconciled where most readers assume it isn't. Knowing the phenomena is recommended so that dismissal is deliberate; studying them instead of practising is named as the trap most people fall into; and the material is said to be unintelligible until you've matched the states yourself.7 Three clauses, one position, all on the same page.
Open questions. Does a tradition that writes down what shows up along the way produce more self-deceived practitioners and fewer realisations than one that doesn't? Both halves get asserted in different places and never put together as the single countable claim they make. And what would a genuinely load-bearing difference between two traditions look like, stated precisely enough that the coating thesis could fail?
The programme and the pictures want opposite things from the same material, and a practitioner deciding what to do this year has to pick one. Take the pictures seriously and there's nothing to choose. Every method is the same method in local dress, so you stay where you are, practise what you were given, and treat the interest in other traditions as tourism. Nothing over there is missing from here.
Take the programme seriously and you have work. Some schools get results faster than others, for reasons you can go and find out; some hold principles yours mislaid; and borrowing is legitimate, has always happened, and is a sign of progress rather than of disloyalty.6 That reading has you reading the other manual with a pencil.
The second is the more useful, and it's the one the argument actually runs on, while the first is what gets said out loud. Against Religious Change Driven by Competition, Not Compassion, the two halves fit together exactly: competitive pressure supplies the motive for borrowing, and the coating thesis supplies the permission, since nothing sacred moves if only the paint is different. Against Method Accepted, Result Rejected, this is the premise that method runs on, stated openly — translating between vocabularies only works if the vocabularies really are coatings, and where a difference turns out to matter, translation has quietly become substitution. And Identical Metaphor, Different Attainment is the demolition charge sitting under the whole thesis, in the same book: two people can use the same words for states that aren't the same state.
Business — Intelligent Imitation: Pattern-Match, Don't Copy. That page's claim is that the transferable thing in a rival's success is the pattern — the mechanism and the conditions it needs — and that copying the visible surface reliably fails, because the surface was fitted to a context you don't have.
The benchmarking questions are that argument arriving in a religious register with the vocabulary intact: what's best from another school, which school gets results faster and why, which practices can we take and how should we proceed.5 The why is the pattern-match. Nobody is proposing a church adopt prostrations because prostrations look effective; the proposal is to work out what prostrations are doing and whether that job needs doing here.
What falls out of the pair is what the coating metaphor does to the borrowing. The business warning is that surfaces are context-fitted and don't travel — the visible practice carries local assumptions with it. The metaphor denies exactly that. If doctrine is a coating and technique is the milk, then technique travels clean and the local material was never doing any work in the first place.
So the framework authorising the borrowing has switched off the check that would make it intelligent. Under one river, many streams there's no such thing as a context-fitted practice, and lifting one can't lose anything — which is the failure the business page exists to prevent, and the failure that happens when somebody lifts a recorded experience out of the life that produced it.
Run it the other way and the business page inherits a problem. Its remedy is to find the pattern beneath the surface, and the difficulty here is that nobody agrees where the surface ends. A commercial pattern gets tested by trying it. A contemplative one, on this book's own account, only becomes intelligible to somebody who has already arrived.
One handshake. A second on comparative method belongs to the sibling pages in this cluster and would restate rather than extend.
Sharpest implication. The imagery and the programme are incompatible, and the programme is the better half. Benchmarking presupposes that traditions differ in ways that matter and that some are faster at some things — live, checkable and useful. One river, many streams presupposes they don't, which would make the benchmarking pointless. The second is the rhetoric; the first is the method.
Generative questions.
