"It was as if I had a good conversation with my subconscious, actually a kind of therapy with myself"
"This past weekend it was time for a journey with magic truffles. What a wonderful experience. I was able to quiet my mind (that alone was a relief) and to connect with my inner world and my own authenticity. I felt and saw a lot. For me a journey in a whole new dimension. Eric and Marieke thank you for sharing your fantastic place and for being there as a spaceholder!"
"Many thanks for the wonderful day and beautiful insights. I wouldn't have missed for the world. I see it as just the beginning of the journey. We see each other again soon."
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’.
"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!"
"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."
"What a fantastic experience this was. A true gift to myself. Many thanks for a provoding such a caring and safe environment."
"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."
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.
A wonderful journey through the unknown. A beautiful start to discover more.
"Thank you so much for our unforgettable experience."
"Thank you for all the good care. A wonderful experience that I want to cherish for as long as possible."
"An exciting new endeavor that is nothing like anything I have done before. But which unfolds in a familiar journey through my innerself and where I could reconnect with my emotions in a warm, beautiful and calm setting, Where untrodden paths can suddenly be walked again is a wonderful gift."
What a liberation, I experienced heaven!
You have made sure that you didn't miss anything. You cared for us with so much love and dedication. I felt at home and safe at all times. I couldn't have wished for a better place for my first psychedelic experience. I thank you from the bottom of my heart for these three days full of insights.
"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."
"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."
"We are in the after glow of enjoying an intensely beautiful experience. Thank you so much for your guidance on this beautiful day!"
"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."
It was again a wonderful experience and so very loving!! Thank you Eric & Marieke
