SEP 2026 Meetup: Know Thyself with Mareesa Stertz

Know Thyself: A Psychedelic-Inspired Participatory Ritual with Mareesa Stertz 📍 Little Yoga Space — Rua da Assunção 42, 1º andar, sala 3, 1100-044 Lisboa (Baixa) 📅 Thursday, September 17th 🕖 19:00 – 20:30 💶 Suggested donation: €10 Every human carries a riddle — a question that loops, a pattern that repeats, something in the psyche still waiting to reveal its meaning. What if you could enter the territory of a psychedelic journey — and unpack that riddle — without taking a psychedelic? Join storyteller and experience designer Mareesa Stertz for a 90-minute participatory ritual using movement, sound, storytelling, and reflection to guide you into the stories shaping your inner world. You'll explore a question or pattern that's been asking for your attention, and discover what lies beneath it. Whether you're curious about psychedelics, preparing for a journey, integrating one, or just ready to go deeper — Know Thyself offers another way in. This is an intimate extension of Sphinx Gate, the immersive art installation that debuted at Burning Man 2025 and has guided thousands through encounters with their own inner worlds. One question before you enter: are you feeling brave? Mareesa Stertz (yourstoryiseverything.com) is co-founder and head of communications and programming for the Global Psychedelic Society (nearly 300 chapters, 40+ countries), co-founder of Lucid News, and founding artist of Sphinx Gate. Her work has been featured in Forbes, Psychedelics Today, and DoubleBlind, and she hosts The Healing Powers of Psychedelics on Gaia TV.
