Family Constellations Circle in Brussels - March
This is an open Circle for anyone and open to constellate on any subject. It's a good way to get started if you've been wanting to see what Constellations is all about. We will start with some bodywork exercises and then there will be time for three Constellations on any topic.
A Constellation is a means for accessing the timeless map you hold within, linking the past to the present and the present to the future. It's a tool to find the origin of the problems we face today such as repeated patterns, blockages, relationship difficulties or health concerns, to name a few, and has the power to reveal hidden dynamics not visible to the normal eye. Then a healing exchange takes place and steps are taken to free you from the past and put you on a road to freedom, understanding and authenticity for your future.
There are two ways to participate, either as a participant or Space Holder in the Circle or to bring a topic to constellate as an Issue Holder, which is limited to three places. Although one person will bring a subject to constellate, everyone participates. A Constellation is a Healing Circle for all who attend.
Price for Space Holders: 50 Euros (12 spots)
Price for Issue Holders: 165 Euros (3 spots)
Date: Saturday, March 14th
Time: 3:00 to 7:00 pm
Location: Shanti Home: Rue Darwin 8, Brussels 1190 (Forest)
\*There are three spots available for Constellations. Contact me if you'd like to reserve one of these spots.
\*Spots are limited for both roles to ensure enough space in the room, although the room is very spacious.
*Modified price for students or if you are unemployed. Write me if this is your case.*Payment must be made beforehand. You can register either to the following account or pay by credit card or PayPal by following the link to the website.

Arguable Authenticity - The Brussels Philosophy Meetup
It is no secret that throughout the history of the (western) world, the individual has played more and more of a central role. When it comes to morality for example, we rarely talk about virtue, duty or the cosmic order, but mostly about pleasure, pain, human rights, … things that pertain to individual persons.
During this meetup we'll discuss what came along for the ride: an idolization of authenticity.
Why is “Be yourself” such an attractive slogan and what does it mean? Is being authentic always better or can it be dangerous? Are populists and extremists not the most authentic politicians?
If we then consider the rise of synthetic materials, plastic surgery, virtual reality and artificial intelligence, is authenticity doomed? Is the popularity of "Reality TV" and online influencers not a sign that authenticity can be gamed? What is the difference between something/someone seeming authentic and actually being authentic?
Or was authenticity an illusion all along? What (in)forms this self we need to be true to? How can we trust our own interpretation of ourselves?
Come and join this philosophical conversation as you are - and try to arrive on time so you can get a drink before we start :)

Silent Walk in the Forêt de Soignes
We will be walking through the forest for a little over 1 1/2 hours, silently, just noticing the world around us and inside us. The idea is to experience the magic of a different type of walking, The invitation is to slow down and notice what is going on inside you and around you.
Very often people experience a closer connection with nature and with self, with sometimes surprising insights.
*Please make sure you are fit enough to go the 4.5 km distance. We will be walking slowly, but we will not take any breaks.*
We will be meeting at the Hermann Debroux Metro at **14h**. (Exit straight ahead after leaving the platform--on the Loxam side).
If you RSVP as coming, please be on time. We will be starting our walk from there 5 min. after the hour sharp.
There is the renovated Maison de Prieur at the exit of the forest where we could gather for a drink or a meal after our walk, depending on what you feel like.
Looking forward to an inward adventure? Come and join us on **Saturday, March 14, at 14h**

✨ Northern Lights in Iceland
This is it—the ultimate window to see the Northern Lights at their strongest in our lifetime. The Sun is reaching the peak of its 11-year cycle, and 2026 will be the final year of maximum activity before the auroras fade in intensity for a decade.
We’re heading to Iceland during the new moon and spring equinox (March 17–23, 2026)—a cosmic alignment that gives us the highest possible chance of seeing the skies explode with color.
🌌 What’s included
6 days/5 nights around Reykjavík & the South Coast
2–3 guided aurora-chasing nights (weather permitting)
Visits to waterfalls, glaciers, black-sand beaches & the Golden Circle
Time to relax in Iceland’s hot springs and enjoy its culture
💡 Why this trip matters
Miss this moment and you may need to wait until the late 2030s for conditions this good again.
🌍 For who?
Travelers who love nature, adventure, and international company. Expect a mix of hikes, sightseeing, and cozy evenings under the stars.
⚠️ Limited spots—reserve early to secure your chance at witnessing the Northern Lights at their peak.

Terracing #1: Spring Social Afternoon
Weather being what it is, we will probably be sitting inside :) .
After several walks and activities together, it felt like a good idea to simply **meet and spend some relaxed time together**.
So this is a very simple gathering:
we meet on the **terrace of the Maison du Prieur at Rouge-Cloître**, have a drink, talk, and get to know each other.
No formal activity, no structure — just a moment to connect with other members of the **Happy Body community**.
If the weather is nice, Rouge-Cloître is one of the most beautiful natural spots in Brussels, with forests, ponds and quiet paths.
Feel free to come for **10 minutes or stay longer**.
Sunday Electronics Workshop
This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept. Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge.
## Requirements
* Bring your own laptop (Windows, Linux or Mac)
* Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you !
* A strong desire to learn stuff, good mood and some patience !
Deep Conversation-- Question Chosen in Session
Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you!
After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations.
Past questions have been wide and not confined to academic philosophy:
What is a genuine friend?
Is social media turning us into emotional zombies?
Do we lose some of the experience of things by defining them?
Are we driven by sex?
Is loneliness a personal failure?
Is morality relative?
**Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.
Non-fiction Book Club: "Your Inner Fish" by Neil Shubin
Let's read and discuss non-fiction together.
In **March** we will be discussing "Your Inner Fish: a Journey into the 3.5-Billion-Year History of the Human Body" by Neil Shubin.
For more information about the book check out goodreads:
https://www.goodreads.com/book/show/1662160.Your_Inner_Fish
How it works:
- 10-15min Introduction round
- 1 - 1,5h Free discussion around the book
- 10min selection of the next book. (We will vote between three possible books. I bring two suggestions and we select a third one from the group. So if there is a book you like to discuss feel free to put it forward.)
Don't worry if you cannot finish it in time. Just join us for a coffee or tea and a good conversation. :)
Happy reading!
Climb & Chill 🧗♂️☕️
What's up Friends! 👋
Ready for some bouldering fun? Boulder-what? 🤔 It’s climbing (FR: escalade, le bloc) up to 4.5m high without ropes—and in my case, without much hope! 😂✨
It’s a super fun indoor activity, but be warned: it does require a certain level of physical fitness and/or skill. Most importantly, though, it requires awesome company—which we’ve got! 😎
The Idea:
📍 Meeting Point: For those arriving at 17:00, we’ll meet at the cafeteria (next to the billiards table).
Feel free to start earlier or later—just drop me a message or write in the group chat so we can meet up.
💪 Stay & climb as long as you want - venue closes at midnight!
🥤 Recharge: If you’ve had enough climbing for the day (we usually do this after 2 hours of climbing), we may head back to the cafeteria (or to the rooftop if it's sunny🌤️) for snacks, drinks & games. Cafeteria closes at 22:00.

🌊 Atlantikwall Raversyde & Ostend Coastal Walk
## 🌍 About the experience
This Sunday we travel to the Belgian coast to explore one of the most fascinating historical sites in Belgium:
**Atlantikwall Raversyde**.
Hidden in the dunes near **Ostend**, this open-air museum preserves more than **60 bunkers, trenches and underground passages** from the German Atlantic Wall built during **World War II**.
Unlike many other sites, the complex remained buried in sand after the war, which helped preserve it almost intact. Walking through the trenches and bunkers gives a powerful glimpse into the reality of the coastal defenses of the time.
After the visit, we will enjoy a **relaxing walk along the North Sea coast**, explore the dunes, and finish the afternoon with **drinks or food in Ostend**.
As always with Sunday Vacations, the idea is simple:
**discover places, meet interesting people, and enjoy the moment together.**
---
## 🗺️ Plan for the day
• Meet at **Brussels central train station and travel to Oostende**
• Coastal tram to Raversyde
• Visit of **Atlantikwall Raversyde museum**
• Walk through the dunes and along the beach
• Optional food or drinks in Ostend before returning
Walking distance: ~6–8 km (easy pace)

## 🎟️ Entrance
Museum ticket: approx **€10**
