There's a moment I keep coming back to from a retreat in the Sacred Valley a few years ago. A woman in her late fifties, seven ceremonies deep into her week, told me she felt nothing. Flat. The medicine wasn't working. She'd sat with ayahuasca dozens of times over the past decade and, in her words, “knew what to expect now.” Two mats over, a first-timer — a nervous software engineer from Berlin — had spent the same night weeping and laughing in what he later described as the most important six hours of his life.

Same brew. Same shaman. Same icaros. Wildly different journeys.

I've thought about that contrast a lot since. And I'm increasingly convinced that one of the least-discussed variables in psychedelic work — more important than dose, sometimes, and often more important than setting — is something the Zen folks call shoshin. Beginner's mind. The willingness to walk into a ceremony without already knowing what it means.

The Burden of Already Knowing

Ayahuasca, psilocybin, San Pedro, ibogaine — every plant medicine tradition warns, in its own idiom, about the trap of the experienced practitioner. The Shipibo have a phrase for it. Mazatec curanderos raise an eyebrow at the seeker who arrives already fluent in their own transformation. Even the modern psychedelic-assisted therapy literature has started nodding at the phenomenon: repeated exposure without genuine openness produces diminishing returns.

Here's why. The brain is a prediction machine. It's very good at pattern-matching, and once it has a template — this is what an ayahuasca ceremony feels like, this is what the come-up is, this is what the visions mean — it starts serving up those templates instead of the raw experience. You stop drinking the medicine. You start drinking your idea of the medicine.

This is why people who've sat many times sometimes describe a strange plateau. The purging still happens. The visuals still come. But the felt sense of encounter — that raw, humbling thing that made you cry the first time — has quietly been replaced by a kind of connoisseurship. You're grading the ceremony instead of receiving it.

What Beginner's Mind Actually Means (And What It Doesn't)

Shunryu Suzuki's line — “In the beginner's mind there are many possibilities, in the expert's there are few” — gets quoted so often it's started to sound like a fridge magnet. Worth pausing on what it actually says.

Beginner's mind isn't pretending you know nothing. If you've done six ayahuasca ceremonies, you know things. You know that the first cup often lands harder than the second. You know that lying down too early can invite discomfort. You know your body's rhythms with the brew. That knowledge is real and useful, and pretending otherwise is just a different kind of dishonesty.

What beginner's mind actually asks is subtler: can you hold what you know loosely enough to notice what's happening right now? Can the woman in the Sacred Valley let go of “I know what this feels like” long enough to feel what's actually there? Because the medicine, whatever it is, isn't repeating itself. Only your interpretation is.

In psychological terms — the Acceptance and Commitment folks call this psychological flexibility — the skill is noticing the predictive thought (“I know how tonight will go”) without treating it as a reliable description of reality. You can know a lot about ayahuasca and still meet Wednesday night's ceremony as its own event, unrepeated.

How Certainty Sabotages Plant Medicine Work

Talk to any experienced facilitator and they'll tell you the same story with different details. Seasoned participants often struggle in specific ways that first-timers don't:

• They diagnose their own experience mid-journey (ah, this is my mother wound coming up again) and stop listening.
• They compare tonight's ceremony unfavorably to some remembered peak.
• They arrive with a preloaded agenda — I'm here to work on X — and miss what the medicine is actually offering.
• They perform the shape of surrender rather than actually surrendering.
• They mistake vocabulary (ego death, integration, the mother) for understanding.

None of this is a moral failing. It's just what happens when a curious mind meets the same phenomenon repeatedly and starts building models. The models are useful. The models are also, eventually, in the way.

First-timers have the opposite problem, of course — they can be overwhelmed, unprepared, prone to reading enormous cosmic significance into what might be their nervous system adjusting to a novel neurochemistry. Neither position is inherently better. But there's something the beginner has that the veteran has to work to reclaim: they don't yet know what's supposed to happen. So they notice what is.

How to Bring Beginner's Mind to a Retreat

If you're preparing for an ayahuasca retreat — first one or fifteenth — this is worth taking seriously as part of your prep work, right alongside the dieta and the packing list. A few practices that seem to help, drawn from what facilitators and long-term sitters tend to suggest:

1. Notice your assumptions before you go. Write them down. What do you expect the medicine to show you? What do you expect the shaman to be like? What are you already sure will happen? You don't have to argue with these thoughts — just get them onto paper so you can recognize them when they show up in ceremony pretending to be insight.
2. Resist the urge to set a rigid intention. Intentions have their place, but a laser-focused agenda (I'm here to heal my divorce) can blind you to whatever the medicine actually wants to work with. Try a softer frame: I'm here to see what's here.
3. Withhold interpretation during the ceremony itself. If a memory or image surfaces, resist the immediate urge to decode it. Let it stay strange. There'll be time to make meaning tomorrow, or next month, or next year. Some of the most important content from a journey only clarifies years later.
4. Compare less. Especially between your own past ceremonies. Every night in the maloca is its own night. The medicine doesn't owe you a repeat performance.
5. Talk less in group share. Or, if you must talk, describe rather than conclude. The story you tell about your journey the morning after has a way of hardening into what happened, and once it hardens, it stops teaching you.

Beginner's Mind in Integration

The days and weeks after a retreat are where beginner's mind matters most, and where most people abandon it fastest. The mind, back in its home environment, gets busy converting the experience into a story: I saw this, it meant that, now I'm changed in this specific way.

Some of that meaning-making is healthy. Some of it is the mind trying to file away something it doesn't know what to do with. The problem is that the tidy narrative — the one you'll tell friends over dinner — is almost always thinner than the actual experience. And once the narrative is set, further insight from that ceremony tends to stop.

Try leaving parts of the experience unresolved on purpose. The image you don't understand. The moment you can't quite place. The feeling you can't name. Let them sit. Journal around them without deciding what they mean. In my experience, the most transformative material from a plant-medicine journey often takes eighteen months to two years to actually reveal itself, and only to people who didn't rush to close the file.

A Note for the Seasoned Journeyer

If you've done a lot of this work, none of the above will be new information. Which is exactly the point.

The trap for the experienced psychonaut isn't ignorance — it's the quiet accumulation of certainty. About the medicine, about your own patterns, about what healing is supposed to look like. Every retreat becomes a slight variation on the last, filed under a category you already have. And at some point you find yourself, seven ceremonies deep, wondering why nothing's happening.

Nothing's happening because you've already decided what happens. The medicine is doing what it always does. You're just no longer meeting it.

The Berlin engineer had one advantage the veteran didn't: he had no idea what was coming. Whatever he received, he received on its own terms. That's not a state you can fake, exactly — but it's one you can invite. By loosening the grip of what you think you know. By walking into the ceremony space as if you'd never sat before, while quietly using everything you've learned to hold yourself steady.

If you're weighing a retreat now — first time or return visit — this might be the most useful preparation of all: not what to bring, but what to leave behind. Curated ayahuasca and plant-medicine retreats across a range of traditions can be browsed on our marketplace here, and whichever one you choose, the medicine will meet you exactly as openly as you meet it.
