Shaped to the person
You were never meant to practise like everyone else.
Delve is a learning pathway shaped to the person walking it — drawing on philosophy refined over millennia, and on physiology we can measure today.
The signal
Attention leaves a trace
Delve reads it. Every four seconds or so the system classifies contemplative state through a Neuro-Yogic model, then corroborates that reading against Western neuromarkers.
The reading
It comes back with a name
Five Chitta Bhūmi. Four are a ladder, Kṣipta to Niruddha, carried as Surface, Emerging, Deep and Profound; Mūḍha is dullness, off that scale.
With its evidence
And it says when it doesn’t know
The neuromarkers sit underneath the Sanskrit label as signed evidence. When an epoch sits further than 2.17σ from every state it knows, the reading comes back indeterminate rather than guessed.
Why most of it doesn’t stick
Everyone is handed the same practice, and then told they lack discipline.
Sit still. Watch the breath. Empty the mind.
It works beautifully for some people, and for everyone else it becomes one more thing they’re apparently bad at. The practice wasn’t wrong. It was wrong for them, on that day, at that point in their life.
The first question
Everything either settles you or wakes you
The old texts name two channels: Iḍā, cooling, and Piṅgalā, warming. Which one you need today is the first thing a teacher decides. Delve puts a reading against that axis, and is plain about what the reading is worth.
The practice is old and specific: pranayama moves the breath deliberately between those channels, swar yoga reads which one is already running so you work with it rather than against it, and mantra holds attention once the breath has settled. Delve teaches these directly — the reading is what tells you whether they're working.

What comes back
Two kinds of answer, and we never let one stand in for the other.
Measured
A sitting is named as one of five Chitta Bhūmi: four a ladder from Kṣipta to Niruddha, with Mūḍha — dullness — off that scale entirely. Scored against published state profiles, and returned indeterminate rather than guessed when the margin is too thin to call.
The tradition’s map
Iḍā and Piṅgalā above, and the guṇa triad — sattva, rajas and tamas — which says what colour the state had rather than how deep it went. Both are read from frontal alpha asymmetry in the EEG, never from your breath or your nostrils — and the correspondence itself is the tradition’s, not a replicated finding. Why we keep saying which is which.
The second question
Then a second question, older than either: does the mind need something to hold — a name, an image, a sound — or is it ready to rest with nothing at all?
Get that wrong and even the right amount of calm goes nowhere.
Six stages
A path that changes as you do
What an eleven-year-old needs is not a gentler version of what you need.
It’s a different practice entirely. The tradition mapped this long before developmental psychology arrived at the same place — a life in stages, each with its own hunger and its own obstacle. We begin with young people, because that is where the shape of a person is still being set.
Bala
8–10
Learns by soaking it up. Rhythm, story, doing it together. Nothing abstract lands yet.
Kishora
11–13
Feeling arrives before reasoning does. The work is learning what the feelings are.
Yuva
14–17
Wants the argument, not the instruction. Give it a framework worth testing.
Taruna
18–25
Choosing a life. Practice becomes something you own rather than attend.
Grihastha
25–60
Practice inside obligation — with no spare hour and everyone depending on you.
Vanaprastha
60+
The loosening of grip. Where silence finally has somewhere to go.

How you’d meet us
In the room
Someone who can see you
A trained teacher, in your school or your centre, watching how you actually sit and adjusting what you’re given.
Personalisation isn’t an algorithm here, it’s a person paying attention, with a framework behind them and a record of what has worked for you before.
At home
Where it becomes yours
Between sessions, the practice you were given. Short, unglamorous, most days. The room only decides what you carry home.
What we stand on
Old enough to have been tested.
New enough to be measured.
The framework is Vedic, and we don’t dress it up as something else.
The mechanisms are measurable, and we don’t overstate them.
We say what is established, what is emerging, and what is the tradition’s map, and we never let one borrow the other’s authority.
Established · replicated, and small
Attention training changes attention. That is the smallest true claim available, and we decline the leap to everything else attention is supposed to fix.
Emerging · an association, not a cause
Slow breathing is associated with raised heart-rate variability. Associated with — not causes, not raises, not improves.
The tradition’s map · not measured, and not hidden
Iḍā and Piṅgalā. The guṇa triad. The five bhūmi. The calendar that predicts which channel runs from sunrise and the lunar day is pure tradition — arithmetic, not a measurement, and we don’t dress it up as one. The live reading that names a sitting Iḍā or Piṅgalā is a different thing: frontal alpha asymmetry, wearing the tradition’s names. No peer-reviewed study maps sattva, rajas and tamas onto EEG, and the nostril-to-hemisphere finding behind that reading has not replicated with modern methods. Both are frameworks we find useful. Neither is offered as evidence.
What remains is a question worth answering properly: does practice matched to the person beat the same practice given to everyone? We think so. We’re building the evidence, and we’ll publish it either way.
Ways in
Start where you actually are.
Open the app and begin today, entirely on your own — or start with a teacher who reads the same practice against a live EEG. Both carry the Delve name; neither is a preview of the other.
What they said afterwards
“I loved using the product. I can see the use case in propelling practitioners to higher levels.”
Priya, teaches a weekly sitting group of 12
“Really unique and interesting project that brings the scriptural knowledge of yoga and meditation to life.”
Manav
“Not seen anything like this… ever! Really cool.”

Questions
Answered plainly, including the parts that are limits.
Get in touch
Tell us who sits with you.
The useful first message is about the room: the group, the practice, and the headband already in it.
- Teachers running a cohort
- How many people sit with you, how often, and what you currently record by hand.
- Practitioners with a headband
- Whether it is a Muse S or a BrainBit, and the browser you would connect from.
- Researchers
- Ask about the golden tests, the 1/f fit, or the state profiles behind the classifier.
It all comes back to one thing: the practice fitted to the person in front of you, and a reading honest enough to say when it cannot tell.
