CORE
Release & Reset
You feel disconnected from the life you created.
You are ready for a change
You may have the career, the house, the relationship.
But there’s still a voice inside that whispers,
There is more….
You feel it in your body.
Sometimes as tension, as resistance. Or a fatigue of keeping up appearances. Needing to better yourself.
You know that something needs to shift.
But what do you really want?
The CORE Retreat is a powerful, immersive 5-day journey that invites you to release what no longer serves you, reset your internal compass, and reclaim who you truly are.
Beyond the facade.
Beyond the avoidance.
CORE is a reset to reclaim your life.
What is CORE?
CORE is not just a retreat experience. It’s a full-body wake-up call with a solid integration programme and CORE graduate community.
Facilitated across 7 countries in the last 10 years, with >200 graduates, CORE is our signature transformational programme.
A deep dive into the roots of your patterns, emotions, and identity.
An invitation to shed the masks, speak your truth, and live in alignment with your values and desires.
We go beyond just needing to think differently and change a mindset.
Working with your body, your sabotaging patterns, your nervous system. We decondition and bring to light the parts of you have kept hidden.
Through movement, dynamic meditations, psychologic inquiries, coaching and inquiry, you will break through what has kept you small, and claim a version of yourself that is more grounded, clear, and alive.
This is real, raw, and without bullshit.
Designed for change.

Esther Lotus Strik | Assistant
Lotus is a professional trainer, team coach, and co-founder of Rise and Shine Academy. With over 15 years of experience, she creates safe, open spaces for groups and individuals to connect deeply and grow.
“CORE is one of the most intense trainings I’ve ever attended. The speed, depth, and rawness made masks fall off quickly, and therefore I was able to go to places I had not yet discovered.
I realized that my deepest fear is an illusion. CORE allowed me to stand stronger and purer in life.”
Yoeri Shi Nelis | Apprentice
Shi graduated CORE in 2023. His skills encompass a broad spectrum from Tantric Temple holder, Breath Repatterning facilitator, and sustainability consulting. He brings skills, calmth, clarity, presence, compassion and grounding.
“My intention with CORE was to connect more deeply with myself in a period of change. Honestly, I also had the thought that I did not have much to learn…
What a big contrast with the deep emotional healing process I found myself in! I am so thankful that CORE has shaken me with so much love, brought me compassion, truth and radical acceptance of every aspect of my life. I look forward to assisting this CORE.”
Sanne ten Wolde | Retreat Chef
Sanne prefers to cook plant-based, sugar-free and with products from her father’s bio-dynamic vegetable garden. The dishes she cooks are therefore very seasonal. I love combining different cuisines with a focus on nutritious, innovative and caring. Her positive, bubbly energy can be felt miles away or actually, tasted in every bite. This week, she is the cherry on the cake.
“I believe my food & love can support building a more beautiful world in the most beautiful way.”

I was stuck in my life and oh so ready to move on. I needed a big nudge and this retreat gave me exactly that, and so much more. I feel now that I am me, I am strong and that I am ready for this world!

There are so many retreat offers, and I can imagine very well that for people who need help don't know where they should be. When they come out of this retreat it is truly a gigantic gift because bullshit is no longer possible.

I recommend it because of the variety of exercises, the combination of tantra with NLP and innerchild work. The rituals embedded in the process. The presence of Karlijn and the assistants during the whole retreat made sure that every personal process was getting enough attention. Also the huge amount of aftercare moments, which has been helping my proces in the weeks after the retreat.

For me the CORE was one of the most impactful retreats that I have ever done in my life. In advance I thought it is an expensive retreat and now I think this retreat is worth every penny! It was a physical and emotional release and reset for me and I came out of CORE much lighter, physically I lost some kilos and emotionally I was very calm and serene; finally the voices in my head were quiet. I have examined and experienced my own judgments, patterns, and fears. As a result, I emerged as a new version of myself from the CORE. There was a new ME!
