During this 4-day Ascension Retreat — with two psychedelic journeys and a Cannabis Circle — renewal and growth take center stage. It’s a beautiful opportunity to consciously explore what deserves more attention in your life, creating space for personal growth.
During this retreat, we give our full attention to both mental and physical wellness.
On Thursday, May 29, we begin at 9:00 a.m. You’ll meet the group and be given space to settle in and feel at home. We’ll prepare you with information and a breathwork session, followed by your first psychedelic journey with a medium dose of psilocybin.
Day 2 begins with an optional early-morning dew walk. After breakfast, we reflect on your first journey and prepare you for the second journey. Before this session, there is time to check in during a 1-on-1 conversation with one of our experienced coaches. The second journey involves a higher dose of psilocybin. Now that you know what to expect, this session often allows you to go deeper and more intentionally into specific themes.
On Day 3, after breakfast, we explore the experiences of both journeys together. This day is dedicated to integration. In the afternoon, we will offer you a Cannabis Integration Circle — a gentle and grounding way to deepen your insights and begin embodying what has become clear.
On Day 4, Sunday, we’ll close with a group reflection and help you bring your insights together — so you can return home (or step into a new phase) with clarity and a fresh sense of direction. The retreat ends around noon.
We choose to offer two journeys because, in our experience, this combination brings the most meaningful insights. The second session often builds upon the first: with greater familiarity, it becomes easier to connect to your subconscious and explore more specific aspects of yourself.
Throughout the retreat, you’ll share a room (a single room is available for an additional fee), you’ll have full access to the garden and nature, and there’s plenty of time to relax — including use of the sauna. We serve fresh, healthy, vegetarian meals with love and care.
This retreat is a true gift to yourself. With the deep relaxation, the insights from two journeys, and the Cannabis Circle, you return to full connection with yourself. This creates the space and clarity to recognize what you truly wish for — and which direction you want to take. It’s a chance to tap into your full potential.
Each participant will have a personal intake call before the retreat. About 2 weeks after the retreat, we’ll meet again in a group Zoom session. Ongoing support after the retreat is included.
Ascension Day Retreat 29 May – 1 June
You're signing up for a 4-day retreat in Culemborg starting on Thursday 29 May 2025 and ends on Sunday 1 June 2025.
Price: € 1.950,-
Ascension Day has different meanings. In Christian there is the belief, the ascent of Jesus into heaven but in Germanic times Ascension was another word for dew-walking. Dew walking was linked to celebrating a new season and the new life in nature. The maypoles that were planted, and which were the center of the feast, symbolized personal growth and the fertility of fields and cattle.
In the Netherlands, it is legal to purchase and consume psilocybin in the form of ‘magic truffles’. Truffles are a different part of the mushroom, known as sclerotia, which remain dormant and help the mushroom regrow after damage. Magic mushrooms, in contrast, are illegal.
Psilocybin is completely safe when used responsibly in a safe environment with people you know and trust. It is a naturally occurring substance that is converted by the body into psilocin, which acts on the serotonin receptors in the brain. Psilocybin is not addictive and there are no known reports of overdoses.
Psilocybin is not an addictive substance. You may enjoy and get a lot out of the experience, but you’re not likely to become physically dependent on psilocybin.
The age limit of 25 years is installed because the brain is still growing and developing up to that age. Important contra-indications as some disorders are found almost always before the age of 25 (but not always before 20). We must take this contra-indication very seriously because of the immense consequences when things go wrong. And as a young adolescent you rather not come in contact with a very high dose of psilocybin, like participants use in our Retreats.
If you are taking medication, consult your doctor before taking any further steps. Before you sign up for a retreat, please let us know what type of medication you are taking. We can also consult our medical expert to help you gain clarity.
What other people say
An overwhelming gratitude
"I arrived with an intention to connect. There was a sense of celebration, too, because my first real psychedelic experience felt like it would be a reward for all the personal development work I have done over the years. When I left that same evening, what I took with me was an appreciation of opposites; overwhelming gratitude for the loving connection to my wife and son; and a sense of my effortless brilliance, coupled with a deep understanding that, whoever I am, I exist only in relationship – it is solely through connection to the people who cross my path and walk alongside me that I am able to shine."

Dealing with the purest form of all my emotions
"I opened the door to my inner self and spent some time in there, dealing with the purest form of all my emotions, answering my most pressing questions, and making peace with my world and self. Beyond that, I connected with the oneness that we're part of, taking a peek at the building blocks of the journey that we call life."
Cosmin
Germany
An unforgettable experience
"It was an unforgettable experience and I look back on our discovery with gratitude. I'm sure there will be more 'loosening up'. I'm looking forward to that. The welcome, care and loving 'holding space' was really overwhelmingly beautiful. You do that incredibly well."
Sandra

It changed my life forever
"It was an intense but unforgettable day and night. I dare say it changed my life forever. In a loving and honest way, Marieke exposed my ingrained habits and beliefs and gave insights that I was not even aware of. The journey, the beautiful location, the delicious food and the beautiful conversations made a deep impression on me."

I wouldn’t want to experience my next psychedelic journey anywhere other than at ‘The Matter'
Eric and Marieke have made a dream come true with 'The Matter' — a place for anyone who wants to grow personally with the help of plant medicines.
The yurt, the music, the apartments, the food, the conversations with the coaches, the program, absolutely everything is just right. It creates a calm and safe environment where you can fully surrender and let go in complete trust — and grow from it. I wouldn’t want to experience my next psychedelic journey anywhere other than at ‘The Matter’.

Connecting to my inner self
"In a beautiful place, where I felt safe and comfortable, I got the opportunity to connect to my inner self in a very special journey. Throughout the journey and the aftermath I was be able to give attention to feelings and thoughts that in daily life I easily ignore. This experience created awareness of my soul and peacefulness within myself."

Incredibly profound and mindblowing - Cannabis Retreat
For me, a psychedelic journey is incredibly profound and also mindblowing. Sometimes the journey is abstract, full of feelings an images who are not so clear to me and sometimes is overwhelming, beautiful full of love and a deep feeling in my body and mind. Afterwards the light always conquer the darker images and experiences, even the dark can be seen different. The cannabis journey gave me 2 journey's in one trip, a mindjourney and a different journey in my body. A profound physical experience like a never experienced before.

Coming home
"Going to Eric and Marieke is always like coming home. Their hospitality is heartwarming and the location fantastic. The whole concept has a 'worry-free' effect. You can and may let go of everything for a while and focus entirely on yourself and your own process. You will be guided where necessary. The trips are sublimely accompanied by appropriate music and the necessary care. If you would like to take a big leap in personal development and do so in a very beautiful way, this is the place to be!"
