Social Entrepreneurs and Changemakers Meetup
Social Entrepreneurs and Changemakers Meetup
Social Entrepreneurship Meetup 🌳 As the afternoon light settles over the city and the garden of the Museum of Literature Ireland comes alive with its quiet charm, we gather at MoLI Café for the meetup — to dream, to connect, and to create together. We welcome those who are interested in making a positive difference — through projects, creativity, entrepreneurship, purpose-driven work, art, education, or technology. Whether you have an organization, a plan, or just a quiet impulse to make things better — you're welcome. The only thing that matters is the desire to make positive change — and to find others who feel the same. To find your tribe. \-\-\- 🌀 The format This is a casual, open meetup — no agenda, no speakers, no pressure. You can talk about projects, ideas, visions — or simply enjoy being around people who dream and feel like you do. \-\-\- ✨ What starts as a coffee can grow into something greater.
📚 Books & Social 🍸
📚 Books & Social 🍸
📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives. Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

Zazen Meditation + Dharma talk or Kinhin
Zazen Meditation + Dharma talk or Kinhin
The meaning of the word zen is meditation, zazen means sitting meditation. In zazen practice we begin to know ourselves, and to go beyond the limits of our personal ego. Within our tradition zazen is referred to as shikantaza, not doing, letting go of thoughts, dropping off body and mind. This sitting meditation is the focus of our practice. Language limits our ability to communicate the true nature of zen; it is something that is better understood through practice. We are open to everyone interested in learning about zen. Intro workshop for newcomers is available at 5.30pm each Sunday. The dojo is a sacred place and it is important to be considerate of everyone. We have many people that travel to practise together once a week or once a month. So for that reason it is really essential that we all know the structure of the sitting practise (when to sit, how to do Kinhin, the different bell sounds and their meaning etc), to ensure a silent, safe and meaningful meditation. And it's also great to meet everyone before the sitting practise. And answer any questions you may have. We have zafus and zabutons (mats and cushions) for all to sit on. Chairs are available too. Comfortable clothing for sitting, black or neutral tones best. We greatly appreciate a donation of €5 to cover costs if it's possible for you. Please arrive 10min before start so 6ish (if you're not doing the intro workshop). You are very welcome to our dojo!
reviving gardans, Growing community
reviving gardans, Growing community
**Hands in the Soil: Community Growing, Learning & Craic** This first gathering will be a relaxed mix of **hands-on garden work, shared learning, and good conversation**. It’s about getting together in a real space, doing something practical, and seeing what ideas and connections might grow from there. On the day, we’ll: * Get our **hands dirty** with some light garden work and soil prep * Do some **seed sowing** and talk about what grows well locally * **Make kombucha together** and chat about fermentation, food, and simple home practices * Share knowledge, questions, and experiences around growing food * Enjoy some **fellowship, chats, and a bit of craic** along the way.Alongside the practical side, we’ll also have an open, informal discussion about a bigger idea: * The possibility of **small community “park farms” or gardens** in underused green spaces around Dublin * What that might look like, what’s realistic, and whether others feel drawn to exploring it further There’s no pressure, no expertise required, and no expectation beyond showing up with curiosity and a willingness to pitch in. Whether you’re experienced with gardening or completely new, you’re very welcome. Bring clothes you don’t mind getting muddy, and if you have them, gloves. Everything else will be very low-key. This is just a **first step** — a chance to meet, work, talk, and see if there’s a shared appetite to keep growing something together.
