Silent Reading / Creating Club at W66 (Saturday) [Luma to RSVP]
RSVP on Luma: [https://luma.com/d70e9b92?utm_source=Meetup](https://luma.com/d70e9b92?utm_source=meetup) ​Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles, whatever you’d like to spend a quiet hour doing. All projects and all participants are welcome. ​This year is about creating more, quietly, consistently, and imperfectly. We're fostering an environment that supports that. If you’re building something of your own, you’re especially welcome here. ​We’re building a community of readers and creators who value depth, presence, and shared silence. The magic isn’t just in the quiet hour — it’s in the people who return and make it feel like a familiar room. ​(Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) ​This quiet ritual unfolds at **W66 Café**. ​There’s no entrance fee, but please order at least one item from the café and don’t bring outside drinks 🙂 ​No assignments, expectations, or pressure. Just a shared hour of intentional silence, followed by the opportunity for good conversation. 🕰 Our Agenda ​**10:30 – 11:00** Arrivals, ordering drinks/food, light social time ​**11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) ​**12:00 – 12:30** Optional socializing — share what you were reading or creating, or simply continue in quiet focus. ## **​🏡 House Guidelines** ​To keep this space calm and welcoming for everyone: ​• Silence during the focus hour (no calls or conversations) • Put cellphones on silent mode • If using technology, please avoid meetings or audio (headphones please!) • Arrive before 11:00 if possible to minimize disruptions

 I WRITE – A Silent Writing Club (Just You & Your Words)
I WRITE – A Silent Writing Club (Just You & Your Words)
Welcome to **I WRITE**, a gentle space for anyone who wants to write—quietly, freely, and without judgement. We are a Berlin community of writers who gather together weekly to write, talk and recharge after a long week. Some of us journal, some write novels, some do academic writing, many people come without a project in mind and see where the inspiration flow takes them. This is a space to simply show up and write, a safe place to be yourself and to release all your layers onto the paper. There’s no set topic, no feedback circle, and no pressure. Just warm people, a calm atmosphere, and time dedicated to yourself. 🗓️ **Agenda:** * 14:30 - 15:00 **→** 30 min arriving, optional socialising (arrive early, meet other writers) * 15:00 - 16:00 **→** 1 hour of silent writing (headphones welcome, focus encouraged) * 16:00–16:30 **→** 30 mins break + optional chat or solo time (stay and chat or go celebrate the rest of your Saturday) * 16:30–17:30 → 1 more hour of silent writing (for those staying) * 17:30–18:00 → 30 mins of chat, and leaving 🎒 **Bring:** * Something to write with (laptop, notebook, phone, typewriter… anything goes) * Something to drink (there is no cafeteria, unfortunately) * Your current project or a blank page * Yourself, exactly as you are **👉 Responsibility:** * Our location is limited; thus, I am kindly asking you to RSVP only if you are willing to attend. **📍Location:** * We meet at **Heinrich Schulz Library in Charlottenburg**. In the library, go look for the Gruppenraum; I will be waiting for you there. Any trouble finding the room, I will come to meet you outside. * 🚇 U7 **Richard-Wagner-Platz** * 🚌 M45 Bus **U Richard-Wagner-Platz** **About me:** Hi, my name is Anastasia. I started this writing club back in May 2025. Since then, it has been hosted weekly at the Heinrich Schulz Library (who is kind enough to allow us to use this room for free). Over this time, I’ve been privileged to meet some of the most creative and kind minds in Berlin. And I would be happy if you joined us. Whether you're an experienced writer or just at the beginning of your journey, you're welcome. If you know how to hold a pen or how to type, there will always be a space for you. Let's write together!

Terrible Football (Saturday)
Terrible Football (Saturday)
Welcome to Terrible Football Berlin!
Do you want to play football but don't want to pay? Are you a bit unfit, a bit old, or a bit Terrible? Want to have a relaxed kick about and a couple of beers after? Then Terrible Football is for you!
Anyone can play: any ability, any age, and any gender. Terrible Football is about miss kicked clearances, sweet half volleys and desperate diving saves. We play in the rain, sun or snow. It's completely free, and always will be. It's open, inclusive and Terrible.
We usually play on Astro (artificial grass) and sometimes on grass, depending on numbers. Bibs, balls, and cones are taken care of! Just bring sporty clothes and a pair of rubber studded football shoes you'll be good to go! You don't need shin pads and we don't allow hard plastic or metal studs.
The exact location of the event is in the Telegram group description (https://t.me/joinchat/OkWQBBcw3b7ptauwrIEfig Still trouble finding us? Send a message in our Telegram group and we'll help you out. You'll also stay up to date with last-minute changes!
See you on the pitch!

🦥 Effortlessness and effortless Practice 🦥
🦥 Effortlessness and effortless Practice 🦥
**🦥 Effortlessness and effortless Practice 🦥** “*It is not what you do, but what you stop doing that matters. [...] In peace and silence the skin of the ‘I’ dissolves and the inner and the outer become one. The real sadhana is effortless.*” (Nisargadatta Maharaj) **One of the fundamental opposites on the spiritual path are effort and effortlessness. The more advanced the practice, the more effortlessness becomes an important quality in the practice. At the same time, most practicioners make a lot of effort on the path.** **Let's meet and share for an afternoon on the topic of effortlessness and effortless practice and it's balance with effort.** “*When you are trying too hard, your effort becomes mechanical, and that defeats mindfulness before it even gets started. [...] Drop your expectations and straining. Simply meditate with a steady and balanced effort. Enjoy your meditation and [...t]he meditation itself will take care of the future.*” (Bhante Gunaratana) 💫 **What this event offers for you:** *Guided Meditations for arriving, calming the mind and tuning into your intuition - Meeting people interested in spirituality (all levels) *Safe Space for sharing - non-hierarchical and non-judgemental - Opportunity to ask just about any question **👀 You may watch one or few of the following Videos for inspiration:** * Adyashanti on effortless effort: [https://youtu.be/0ZxRrfZTj9I?is=jTGL1qspGosYmxch](https://youtu.be/0ZxRrfZTj9I?is=jTGL1qspGosYmxch) * Angelo Dilullo on "Simply always awake": [https://youtu.be/l2LZvO9wotM?is=AGxDMQem6AL2MJAn](https://youtu.be/l2LZvO9wotM?is=AGxDMQem6AL2MJAn) * Dean Sluyter on the Guru Viking Podcast "on "Effortless Awakening": [https://youtu.be/hWn63b4f490?is=tHMv8coTga2jhci5](https://youtu.be/hWn63b4f490?is=tHMv8coTga2jhci5) * Mingyur Rinpoche on effortless meditation: [https://youtu.be/2va3j-Ub3B0?is=lE3T-MMxF8eFpQeH](https://youtu.be/2va3j-Ub3B0?is=lE3T-MMxF8eFpQeH) * Swami Sarvapriyananda on effortless meditation: [https://youtu.be/1GkNIs3H2OA?is=HVcNEgoYuasFuNHb](https://youtu.be/1GkNIs3H2OA?is=HVcNEgoYuasFuNHb) * Shinzen Young on "strong determination sitting": [https://youtu.be/xVUtUguRc5s?is=YWH_wRWTJb3Ooqc5](https://youtu.be/xVUtUguRc5s?is=YWH_wRWTJb3Ooqc5) * Sadhguru on "Meditation is effortless": [https://youtu.be/7uV-dZuxAXg?is=yiKvnjwUsUFOQ7oM](https://youtu.be/7uV-dZuxAXg?is=yiKvnjwUsUFOQ7oM) **🧘 About the Organizer** Martin is a certified Mindfulness Teacher, Systemic Coach, Yogi and Altruist by heart who teaches Meditation and Martial Arts in different formats. However, in this meetup Martin focuses on the altruistic intention to open a space for people to share while offering as much facilitation as needed in the moment. “*What is the use of truth, goodness, harmony, beauty? They are their own goal. They manifest spontaneously and effortlessly, when things are left to themselves, are not interfered with, not shunned, or wanted, or conceptualized, but just experienced in full awareness. Such awareness itself is sattva. It does not make use of things and people — it fulfils them.*” (Nisargadatta Maharaj)

#6 social reading club – Kreuzberg · Tempelhof (DE)
**Come together. Read. Talk about it.** Vielleicht liest du viel und vermisst Gespräche darüber. Vielleicht hast du Lust, neue Menschen kennenzulernen – in einem entspannten, ungezwungenen Rahmen. Lesen verbindet, und genau dafür ist dieser Club gedacht. Dieser *Social Reading Club* ist für Menschen, die gern lesen und sich genau das wünschen: mehr Zeit dafür – und Raum für Austausch mit anderen, die das genauso fühlen. Wir treffen uns in einem Café am **Platz der Luftbrücke in Kreuzberg**. Nicht als klassischer Buchclub mit Vorgaben oder Pflichtlektüre, sondern als gemeinsames Innehalten: jede\*r liest für sich, egal ob Zeitung, dicker Roman oder Sachbuch. Im eigenen Tempo. Danach kommen wir ins Gespräch – ganz natürlich, ohne Erwartung.

Wir kommen an, bestellen etwas und richten uns ein. Dann lesen wir, zusammen, in Stille – konzentriert, jede\*r für sich.

17 km Round tour between Dahme and Großer Müggelsee (5.5 km/h)
Sunday will hopefully be a sunny day. We’ll meet at S-Bahn station Grünau, on the sidewalk level inside the station (exit Adlergestell/Wassersportallee). We will hike this tour: https://www.komoot.com/de-de/discover/S%E2%80%91Bahnhof_Berlin-Gr%C3%BCnau/@52.4128380,13.5736270/tours?sport=hike&map=true&toursThroughHighlight=388182&focusedTour=1268215602&pageNumber=1 , but make a shortcut in the middle of the tour. Please prepare for a rather speedy hike. (Bring comfortable shoes, for instance.) There are no cafés or restaurants along the way, so bring your own food and drinks. If you need to contact other participants during the hike (for example, to find out where to meet us if you are running late), please use the Signal group link that I will send to all participants via private message three hours before the hike. This timing is intended to prevent non-participants from misusing the link for unwanted advertising, which has happened in the past. Signal also allows us to share our locations during the hike without involuntarily forwarding this information to the intelligence services of authoritarian or non-authoritarian states. For all other purposes, especially socialising and posting photos, please use the Telegram subgroup 'Event Chat & Photos': https://t.me/addlist/KAOk2PA4BDE0ZTY8 . The hike will take place if at least 6 people sign up. As long as there are more than 6 people, you can sign up and cancel as many times as you like. If there are 6 or less people, please avoid cancelling, as this might make the other participants feel insecure about whether the hike will take place (or whether there is something wrong with the hike and they should cancel as well --> [Matthew effect - Wikipedia](https://en.wikipedia.org/wiki/Matthew_effect)). If there are less than 6 participants, the hike will also take place unless the majority of the participants are in favor of canceling the hike.

Humanist Program
Humanist Program
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot.

Bad Girls Book Club April 2026
Bad Girls Book Club April 2026
**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .

Let me know if you’d like a free digital copy of the book) * This event will be at the main library, meeting room 1B, the location will not be changed for this event due to the number of people attending, we will just add more chairs if needed! * Feel free to come whether or not you’ve started or finished the book ◡̈ * Small snacks will be provided. You’re welcome to bring your own snacks & drinks too! Starting in June I will try to keep future book clubs at the Dublin Library. Now that I understand their reservation system, I will be on top of it with booking that location as soon as the date is released for the month. Thanks for your understanding with the varying locations in the meantime.
