Welcome to join our Sahaja Yoga meditation meetings in English! The meetings are free of charge and you can just show up. The group consists of people of different ages and nationalities who have been meditating different periods of time. Newcomers are welcome at any time. We normally sit on chairs or on pillows on the floor, so there is no need to bring a mat and you can wear normal clothes. Meditation means mental silence or thoughtless awareness. You are present here and now, but your mind is not bombarded by thoughts from the past or the future. In this state, you feel peace and joy, which are the essential elements of the present moment. With regular practice of meditation, it is possible to establish this state within us. The group is lead by volunteers who are experienced and can offer guidance to get you started. We give a short introduction to the meditation and after that we do meditation exercises. We also give tips on how to meditate at home. After the meditation class, we have a cup of tea and there is time for questions. Welcome! We hope to see you in our meditation meetings!

We thought it would be nice to start the summer right, in good company, in a relaxed setting. So, for the first time, the HDW Low-Key Data Meetup takes place at the [Olarin Panimo Taproom](https://olarinpanimo.fi/taproom/) at Konepaja, Vallila. We'll be outside, weather permitting, so it's also the perfect start for the 'terrace season'. And if it happens to rain, we'll just be inside instead. If you're coming from the city center, Tram number 9 is probably the easiest to take. A couple of words about Helsinki Data Week at the beginning. After that, it’s again just hanging out with like-minded folks and your beverage of choice! Free for participants! Join us in Olarin Panimo Taproom at 17:00 on Thursday, June 4! ps. Following a spring cleaning of his bookshelf, Antti will have \~20 (mostly data) books to give away. First come, first served!

This week's event is **unhosted**. Worry not though, we're still likely to have \~20 people from our group playing games at Arkade. Pay the **5 € board gaming fee** to the bar at the counter when you arrive. You must be at least 18 years old to enter [Arkade](https://www.arkade.fi/). We play in English and the game rules are taught before starting play, unless everyone is already familiar with the game. No previous experience with board gaming required. Despite our RSVP numbers here on Meetup, we almost always have at least 20 people participating weekly. The venue has a great board game library, the host and other players usually bring their own games too: our selection varies weekly. We're a very casual group so you're welcome to arrive early or late and join whatever game is starting up, there is no attendance tracking, or welcoming process. The bar has alcoholic drinks, mocktails, and soft drinks available as well as some snack foods. They've been okay with people ordering food to the bar with meal delivery services. If you are feeling sick, please stay home.

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.

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.
