Chitta Walks - Awareness in Motion
Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease.
This walk is a simple reset.
We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment.
No apps. No performance. Just a clear space to slow down and notice what is happening.
If you want to slow down without withdrawing from life, join a Chitta Walk.
✨ **What to expect (approx. 90 minutes):**
* A short arrival and orientation
* A guided silent walk (phones off, no conversation)
* One concise science-based impulse on attention or stress
* Optional reflection in pairs or small groups
* A simple takeaway or experiment for daily life
🚶**Who this is for:**
* Professionals, creatives, and people in transition.
* People who feel mentally busy and want more clarity and balance.
* Those curious about mindfulness, but grounded and practical.
* Anyone comfortable with silence and gentle self observation.
🔔 **Practical notes:**
* Duration: 60-90 minutes
* Wear comfortable shoes and weather-appropriate clothing
* No prior experience needed
* Group size is limited to keep the space quiet and focused
🧭 **Facilitator:**
My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction.
🤔 **Why Chitta Walks?**
Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense.
Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world.
The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it.
🌿 **Possible effects:**
A calmer nervous system.
Clearer attention.
A felt sense of being more present in your body.
Subtle insights into how your mind reacts under everyday conditions.
A quieter, more grounded way of moving through the city.
**Come as you are. Walk. Notice. Leave with a little more space inside.**

Blood on the Clocktower at Manifesto! (beginner/intermediate)
Hi folks, this is the meetup group for the weekly Sunday Blood on the Clocktower games in the Soot bar in Manifesto at Potsdamer Platz. We run beginner-friendly and intermediate-level games throughout the afternoon and evening. **Friendly newcomers of all skill levels are welcome, no experience required!**
Our group aims to provide a fun and welcoming space to experience this thrilling game of social deception. **We focus on promoting a positive and fun group atmosphere, where players don’t take themselves or the game too seriously, whether they’re heroically winning or spectacularly losing.** Our players follow the code of conduct for the Berlin Board Gamers group and are expected to treat each other with respect and consideration – “killing with grace, and dying with dignity”.
We are usually able to offer two simultaneous games on Sundays. If you are marked as "attending" in Meetup and are in your seat at 15:00, your place is guaranteed for as long as you want to stay. All other seats are first come, first served. We always run at least one beginner-friendly game of the basic version of Clocktower ("Trouble Brewing") throughout the afternoon and evening. We also usually have enough players for a second intermediate-level game. If you are already very familiar with Clocktower, consider also joining our Tuesday meetup for advanced players, when we play with complex custom scripts and characters.
Blood on the Clocktower is a deep, mechanical game of murder and mystery, lies and logic, deduction and deception… think Werewolf on steroids. Each player receives a unique secret role and plays either for the good team – the uninformed majority, gathering info and working with others to solve the puzzle – or the evil team, the informed minority, scheming to eliminate good players and protect their demon from execution. In our beginner games no prior experience is expected and we will gladly explain the game rules to any newcomers.
We play in English so players should be able to understand and express themselves in English: an exception is possible for one pair of players willing to play together (as a “Revolutionary” pair) where one player can interpret into and out of English. Please let us know in advance if this is the case.
We are very grateful to the wonderful folks at Manifesto for hosting our meetup! **Please support the venue during your visit by buying drinks and/or food.**
Coffee, Games, & Views ☕️ 🎲 🃏🌳: Sunday @ the Spree
Join us this Sunday for a relaxed afternoon of good coffee, great conversations, and board games at Exclusive Coffee on Brückenstraße!
Located right by the Spree, this beautiful two-storey cafe features massive glass windows overlooking the river, giving us a wonderful waterfront view while we play and chat. If you’re worried about the summer heat, don’t be; the venue is spacious, airy, and well-ventilated.
Whether you’re a regular or joining us for the very first time, come along to enjoy an iced coffee, play some light board games (no competition stress), and meet new people in a relaxed, friendly atmosphere.
To keep the gathering comfortable, attendance is limited, so please RSVP to reserve your spot. If your plans change, we’d really appreciate it if you updated your RSVP so someone on the waitlist can join. 😀
Reading Party ☕️📚
\*\*\*\*\*\*
***For address and more details see the website www.pausify.org***
\*\*\*\*\*\*
**Event Info:**
Pausify is the **biggest community and most active** of book lovers and creatives in Berlin.
Impressions: Instagram: **[@Pausify (Co-Reading Space)](https://www.instagram.com/pausify_org/)**
Events happen every Sat and Sun at 11 AM.
Bring along your **current book to read** (or something **creative** to work on) and join us for this mix of a shared focus time + discussion.
\- 11:00\-11:30 \- Meet & greet
\- 11:30\-12:30 \- Silent focus time
\- 12:30 \- Discussion of books/ projects over coffee
Afterwards, join for lunch if you'd like (optional).
**Drinks & snacks are included** ☕️
* **To reserve your place, a ticket (€9,90/event) or a community pass (only €17,90/MONTH) [from the website ](https://pausify.org/)*www.pausify.org* is required**
* **Attendance here doesn’t show all sign-ups from other platforms. We usually have about 50 to 100 people at each event.**
***FAQ: Why does it cost money if I bring my own project?***
Because we rent a beautiful, central space for every event. Ever thought your monthly apartment rent was too high? Well, multiply that – that’s what commercial spaces in big cities like Berlin cost *per hour*.
Of course, if all you want is just some quiet time, your home or a library is perfect. But if you’d like to focus & connect with others in an inspiring space – with drinks, snacks included – that’s what your ticket helps to cover.
See pics from our events below - and on our Instagram: **[@Pausify (Co-Reading Space)](https://www.instagram.com/pausify_org/) ☕️**

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
The Non-competitive Tennis Partner Program
We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level. This program is less competitive, no champions crowned, no league standings just dedicated tennis partners who want to meet up with you on the courts. Players will meet up to play a tennis match or just to hit around. Just go through the [Join Page](https://www.tenniscolumbus.com/partner-program) to enter this program.

IxDA Chat n Pancakes
You can sleep in on the Semiquincentennial (observed), we’re shifting to the following Friday.
But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to.
Thanks to the team at Nationwide of supporting the group.
Columbus Comedy Improv Meetup at Gresso's!
Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**!
The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*.
Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off!
Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

How to Be a Better Communicator - Free Seminar
How to be a Better Communicator
Communication is everything in life
You are only as successful as your ability to communicate.
\- What if you could confidently talk to anyone?
\- What if you had the ability to calmly control every conversation?
\- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence?
You can!
The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate.
