Tervetuloa mukaan Sahaja Jooga -meditaatiotilaisuuksiin suomeksi! Tilaisuudet ovat maksuttomia, ja voit tulla paikalle ilman ennakkoilmoittautumista. Istumme yleensä tuoleilla tai lattialla tyynyillä, joten mattoa ei tarvitse ottaa mukaan, ja voit pukeutua tavallisiin vaatteisiin. Meditaatio tarkoittaa mielen hiljaisuutta tai ajatuksetonta tietoisuutta. Olet läsnä tässä hetkessä, mutta mielesi ei ole täynnä menneisyyden tai tulevaisuuden ajatuksia. Tässä tilassa tunnet rauhaa ja iloa, jotka ovat nykyhetken olennaisia elementtejä. Säännöllisellä meditaatioharjoituksella tämän tilan voi saada vakiintumaan meissä. Ryhmää johtavat vapaaehtoiset, joilla on kokemusta ja jotka voivat ohjata sinut alkuun. Annamme lyhyen johdatuksen meditaatioon, minkä jälkeen teemme meditaatioharjoituksia. Annamme myös vinkkejä meditaation harjoittamiseen kotona. Tervetuloa!

Learning Finnish in Finland can be difficult because Finns tend to switch to English. That is one of the reasons people like our Finnish language café: you get to practice Finnish with Finns :) The events are completely free and there is always a native speaker to facilitate the conversation and to help find the right words. The coffee is good too ☕😋🇦🇹 Tervetuloa! When? ⏰ Usually Tuesday to Friday from 15:00 - 16:00 Where? 📍 In a cozy Viennese coffee house: The Good Coffee Company, Eerikinkatu 33, Helsinki The Good Coffee Company A Taste of Vienna 🇦🇹 Eerikinkatu 33, 00180 Helsinki Please visit our Facebook page for updates and changes: https://www.facebook.com/TheGoodCoffeeCompany/events

You have to check this [sign-up page](https://7538e9.myshopify.com/products/competitive-game) to see if there is still a slot available there. * The background of using an external sign-up and payment system is because Meetup.com introduced a service fee to increase 21% of the fee in May 2023, and we want to reduce this cost. 【FEE and REFUND POLICY】 * Fee includes courts and the work I do to continue this group.

Please remember, the court booked for you is there and it costs money. The court doesn't simply become "free of charge", just because you didn't show up. 【COMMUNICATION】 * Communication: our whatsapp group [https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347](https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347) * There are too many spams, so I only accept +358 number to join whatsapp group.

We have spare ukuleles if you don’t have one of your own. **15:30 to 17:30 - Jam Session Part 1** As more experienced players turn up, we will play a range of songs which everyone can join in with. This is when the sing-a-long / play-a-long really starts. The second part of this session often has a theme around an artists, genre or season. Each song has an instrumental section, and we encourage people to improvise, harmonise or just to play it as they feel it. **17:30 to 18:00 - Food Break** Grab something from the menu, chat to your fellow players, meet new people. Look through the song book. Start playing random stuff. **18:00 to 20:00 - Jam Session Part 2** We will play some more advanced songs. The last part of the session is requests from the jam group. Come and join us for a play-a-long jam. We will be based in the cellar bar at Iguana on Mannerheimintie. We keep it simple ... we put the words and chords on laptop. Please bring a tablet if you have one so you can also access the songbook at ukejam.online ... or you can use one of our TV screens we will have dotted around the place. We will have a limited number of spare ukuleles and guitars. If you don't play anything, you are welcome to come and just hangout, sing if you want to. If you like, pick up a ukulele, and someone will help you play a few simple chords and play along. If you have your own instrument, it is best to bring it. Also if you have a tablet, you can access the songbook at ukejam.online and then you don't have to stare at the TV screen all night. Everyone is welcome ... we also have a community WhatsApp group that you can join when you come to the event. We aim to be a safe and inclusive space for everyone.

**Welcome to Sketchy Collective!** A relaxed and social drawing group for anyone who enjoys sketching — or just wants to give it a try. \*\*\* We meet **every Sunday at 15:00** in **Oodi Library**. \*\*\* **HOW TO FIND US** We meet on the **top floor of Oodi Library**, on the stairs **opposite** the children’s area. It's a good idea to **keep your sketchbook visible** so others can easily recognize that you're there for the sketching meetup. And if you’re a regular participant, making it clear that you're part of the sketching group can be very helpful for newcomers! \*\*\* **HOW IT WORKS** At each meetup, attendees take turns being the model for a quick **10-minute sketch session**. One person poses, everyone else sketches, then we rotate. \*\*\* **WHAT TO BRING** Pencils and paper (or any sketching tools you like). No fees, no pressure. The only thing we ask is that everyone takes a turn posing for the group. You can sit however you feel comfortable — the 10 minutes go by quickly! Draw as much as you like, skip a round if you’re tired or just want to chat, and leave whenever it suits you. The event continues as long as there’s interest. \*\*\* **STAYING CONNECTED** Due to issues with spam and advertising, the group has decided that **only people who have attended at least one meetup will be accepted into the WhatsApp group**. To be added, please ask other participants at the meetup — a few members have permission to approve new people, and at least one of them will likely be present. \*\*\* **SOCIAL MEDIA** If you’d like to share your drawings from the meetup, you can send on WhatsApp group or use the Instagram collab function (instagram.com/sketchy.collective). We warmly encourage everyone to share their work and take part in building our international sketching gallery — together with artists from all the cities where Sketchy Collective meetups are organized.

If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is sponsored the Dianetics & Scientology Self-Improvement Center.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This class is held at the Dianetics and Scientology Life Improvement Center.
