Centre EPÉU — One-to-one retreat
La Maîtrise
The continuation of the Mental Treatment: learning to steer your mental states yourself.
6 days · one-to-one · Château de Villereglan
What it is
“A rider does not take away his horse’s strength. He directs it.” This is a sentence from the Manifesto of the Centre, and it is the whole subject of La Maîtrise.
After the Mental Treatment, the old reactions have lost their strength. But you do not yet know how to steer your states yourself. Something has opened; control has not followed. This is normal, and it is exactly this passage that La Maîtrise works on.
Four gestures
For six days, you learn nothing new to believe. You practise four gestures: recognising the state you are in, changing it deliberately, holding the position, then releasing (fig. 1).
These are gestures of the mind. Like all gestures, they fail at first, then they become available. You leave with your personal programme, to continue alone: that is the aim of the week.
Six days at the Centre
6 days · €2,800
Six days in residence at the Château, one-to-one. Each day, structured work. Over the week, individual sessions of directed suggestion in the hypnotic state, with M. Mischa Harmeijer.
The Δ Delta Score record serves as the measure: the curves of the week are read together. They show what impressions do not.
The ends of the days are free and silent. The work continues during rest; that is even where it settles.
The precise course is individual: it is explained to you during the consultation with M. Mischa Harmeijer.
Who can come
La Maîtrise is for those who have done the Mental Treatment, and who have kept up their practice since. It does not follow straight on from the Treatment: it is earned through practice, and the decision is made at home.
The condition is simple: at least thirty days of daily Δ Delta Score records since the end of the Mental Treatment, kept regularly. The quality of the scores does not count. Only consistency counts, including and above all on difficult days.
Everything begins with a consultation with M. Mischa Harmeijer.
Afterwards
Most people leave with what they came for, and that is an end in itself. For those who want to go further, there is a continuation: La Perception. It is decided later, at home, never at the Centre.

Setting
La Maîtrise is neither care, nor therapy, nor a rest stay.
It replaces no medical or psychological follow-up — if you are currently being followed, the written agreement of the practitioner who supports you is required, as for all the Centre’s approaches. And it promises no result: the training produces its effects through practice and keeping it up, at a pace that varies from one person to another. What is guaranteed is what depends on us: six days of structured, individual work, and a programme to continue.
You can interrupt your stay at any time. This decision is entirely yours and does not need to be justified. The setting is demanding, it is never a constraint: nothing keeps you at the Centre. The conditions that apply in case of interruption are set out in the terms and conditions.
Ongoing psychiatric or psychotherapeutic follow-up
Admission remains possible, subject to the written agreement of the practitioner who follows you. This document must state that they have been informed of the conditions of the retreat, namely six days of individual work in residence, and that they see no contraindication.
If this document was not requested during your consultation with M. Mischa Harmeijer, it will be asked for at registration.
In case of suicidal thoughts or immediate risk, this retreat is not suitable — call the emergency services immediately (15 or 3114 in France).
The first step
A consultation with M. Mischa Harmeijer.
Admission to La Maîtrise never happens by simple registration. It always begins with a consultation with M. Mischa Harmeijer.
During this consultation, M. Mischa Harmeijer listens, observes, and looks at where your practice stands since the Mental Treatment. He assesses whether La Maîtrise is the right answer for you, at this precise moment of your path. If it is not, he tells you clearly — and points you towards what will be more suitable for you.
What comes before admission
The condition is measurable: at least thirty days of daily Δ Delta Score records since the end of the Mental Treatment, kept regularly. The quality of the scores is not taken into account — only the consistency of the practice is looked at, including and above all on difficult days.
Final admission is granted at the end of the consultation. If it is confirmed, a date is set, and the precise course of your six days — individual — is explained to you.
The number of retreats conducted each month is strictly limited — because this work requires M. Mischa Harmeijer’s full availability, and no one can conduct several trainings at the same time.
First step
Make an appointment
The consultation takes place at Centre EPÉU or by video call. It is booked online.
La Maîtrise belongs exclusively to an approach of training in the mastery of mental states. It is neither a medical act, nor a psychotherapy, nor a care arrangement. In case of ongoing psychiatric or psychotherapeutic follow-up, the written agreement of the practitioner who follows you is required before any admission.
Your questions
Is it suitable for everyone?
No — La Maîtrise is reserved for those who have completed the Mental Treatment and kept up their daily practice since. A consultation with M. Mischa Harmeijer determines whether it is the right moment.
Can I do it without having completed the Mental Treatment?
No. La Maîtrise is the continuation of the Mental Treatment — the order matters. That is where the work begins.
What is the admission condition?
At least thirty days of daily Δ Delta Score records since the end of the Mental Treatment, kept regularly. The quality of the scores is not taken into account — only the consistency of the practice is looked at, including and above all on difficult days.
Can it follow straight on from the Mental Treatment?
No. The retreat does not follow straight on from the Treatment — it is earned through practice, and the decision is made at home, at a distance from the Centre. The order matters, and so does the pace.
Where does the consultation with M. Mischa Harmeijer take place?
At Centre EPÉU or by video call. It is booked online: make an appointment.
How long does La Maîtrise last?
6 days, one-to-one, at the Château de Villereglan.
What is the price?
€2,800, complete residential retreat. In one payment or in three instalments at no extra cost.
In which language is it conducted?
Individual retreat: it can be conducted in French, Dutch or English.
Is the course of the six days published?
No: it is individual, and it is explained to you during the consultation with M. Mischa Harmeijer that precedes any admission.
Is it a therapy or a medical act?
Neither: a training in the mastery of mental states. La Maîtrise replaces no medical or psychological follow-up. In case of ongoing psychiatric or psychotherapeutic follow-up, the written agreement of the practitioner who follows you is required.
What happens if I want to stop during the retreat?
You can interrupt your stay at any time. This decision is entirely yours and does not need to be justified. The setting is demanding, it is never a constraint: nothing keeps you at the Centre.
When do I pay?
Payment does not take place on this site: it happens at registration, once admission has been granted, in one payment or in three instalments at no extra cost. In three instalments, the first is paid at registration, the second thirty days later, the last at the latest seven days before arrival. Its terms are set out in the terms and conditions.
Medical support
A general practitioner at your side.
Centre EPÉU works with Dr Séverine Jalet, general practitioner, homeopath and acupuncturist. This collaboration allows consistent support for subjects whose situation requires medical follow-up complementary to our approach.
When a consultation is necessary
Some approaches offered by the Centre may require a prior medical check-up. If your situation calls for it, an appointment with Dr Jalet will be asked of you before the work begins.
If you are currently in therapy or under the supervision of a psychiatrist, the written agreement of the practitioner who follows you is required.
Looking for a general practitioner?
If you do not have a regular doctor, or if you are looking for a practitioner open to complementary approaches, Dr Jalet receives patients at her practice for general medicine, homeopathy and acupuncture.
