**SUBSCRIBE TO [THE MAILING LIST](https://torontorationality.beehiiv.com/). EVENTS ARE NO LONGER POSTED HERE.** ​Arguing about important things doesn’t usually lead to people changing their mind. Double Crux is a technique for making discussions more productive and understanding the actual reasoning of those who disagree with us. Sometimes it even helps to better understand the foundations of your own beliefs. Together, we'll learn about [Double Crux](https://www.lesswrong.com/posts/ya59PtGeYnCG25eWn/double-crux-in-a-box), and then break into pairs with someone we disagree with to practice finding out why our views are different and what might change our minds. ## Location Enter the Mars Atrium via University Avenue entrance. We'll meet at the food court in the basement. I'll be wearing a bright neon yellow jacket. ## Detailed Directions to the Food Court Enter from University Avenue and walk east until you see escalators. Take the escalators down. The food court is to the east of the escalators. If you are lost/confused, ask a security guard to direct you to the food court.

**In-Person Light Body Expansion Activation** Join us for a powerful in-person Light Body Expansion Activation — an immersive energetic experience designed to awaken your life force energy and expand your consciousness. This session combines **Kundalini (life force) activation and Light Language transmission**, creating a space where deep healing, emotional release, and expanded awareness can unfold naturally. As you lie comfortably on your mat, you will receive a transmission of energy that supports the awakening of your own inner life force and the expansion of your energetic body. Participants often enter deep meditative or altered states as the body responds to the vibrational frequencies of sound, energy, and light language. These frequencies communicate directly with your consciousness, activating the body’s innate intelligence and natural healing capacity. This experience supports a deeper connection to your authentic self while helping release energetic blockages and limiting patterns. **During the session you will experience:** • A heart-opening ceremony to deepen connection and receptivity • Demonstration of the activation process • Full Light Body Expansion Activation energy transmission • Light Language channeling and vibrational sound frequencies • Somatic and energetic release as the body responds to the energy • Closing integration and sharing circle **Participants may experience:** • Spontaneous body movements or energetic sensations • Emotional release such as laughter, tears, or deep peace • Visual or intuitive insights • Expanded states of consciousness • Activation of the voice through humming, singing, or light language **Potential benefits:** • Release of emotional and energetic blockages • Expansion of awareness and consciousness • Greater intuition and clarity • Reconnection with your inner guidance and purpose • Increased creativity, joy, and emotional freedom All you need to do is lie down, relax, and allow the energy to guide the experience. Please book your spot [here](https://lightbodyexpansion.com/class/4)

🌆🚶‍♂️ THE PATH WALK & LUNCH ADVENTURE 🚶‍♂️🌆 Toronto’s Underground City… Let’s Go Get Lost (On Purpose) Did you know Toronto has an entire second city beneath the city? Welcome to **PATH (Toronto)** — a 30-kilometre maze of tunnels, walkways, food courts, shops, office towers, and hidden corners connecting more than 70 buildings in the downtown core. It’s climate-controlled. It’s slightly confusing. It’s uniquely Toronto. And we’re going to explore it together — above ground first, then descending into the urban underworld like the confident city adventurers we are. [NOW Magazine piece](https://web.archive.org/web/20220429041937/https://nowtoronto.com/lifestyle/health/toronto-walk-exploring-the-path-in-winter) about the PATH awhile back. 👉 **Don’t forget to join our WhatsApp group** – [CLICK HERE!](https://chat.whatsapp.com/H59mSCbsAi018gYANrKAnc?mode=ac_t) \*\*\* 🗺️ The Plan We’ll begin at Wellesley Station and start by walking west. Then we’ll head south and eventually make our grand entrance into the PATH system. From there, we’ll continue indoors, weaving our way south through the network — past office towers, hidden corridors, and pockets of unexpected energy — all the way down to **Union Station**. At Union, we’ll head into the food court to grab lunch, sit down, and actually socialize (because that’s the point, right?). Expect lots of conversation, a little “Wait… where are we?” and a whole lot of discovering how this city secretly works. It’s part walking tour, part social hang, part urban exploration. \*\*\* 🌧️ Rain or Shine (Mostly Shine Because… Indoors) T his walk goes ahead rain or shine. The beauty of the PATH? We’ll be indoors for large portions of the route. That said, we’ll start above ground — so dress appropriately. It may be wise to bring a backpack or bag for your coat once we’re inside. You don’t want to be carrying it dramatically over your arm like you’re in a soap opera. \*\*\* 🐾 Important Notes Dogs are not allowed in the PATH system. Service animals are of course welcome. \*\*\* 🧢 Meetup Details 📍 Meetup Spot: Main entrance of Wellesley Station (near the bank of PRESTO machines) 🫎 I’ll be wearing my Moose Hat ⏰ Start time as listed — please arrive on time We’ll begin promptly so we can stay on route. \*\*\* 🎟️ **Meetup Fee:** $5 cash in person **or** e-transfer to 📧 \*\*[mathewmaclean@hotmail.com**](http://mathewmaclean@hotmail.com%2A%2A/) This fee helps support the group and allows us to keep hosting events like this. Thank you for supporting community! 💖 \*\*\* 🌈 Who Is This For? This group is open to anyone who wants to be social and make friends — whether single or not. We also host: 🎬 Movies 🚶 Walks & hikes 🎭 Arts & culture outings 🍽️ Restaurant meetups There’s always something happening. And remember — you can just show up on the day if you’re unsure about your schedule. \*\*\* ⚠️ A Gentle Reminder Sometimes life throws curveballs and events may need to be canceled — please keep an eye on updates. \*\*\* 👤 Organizer: Mathew Questions? Post on the event wall or email 📧 [torontomoviesandoutings@hotmail.com](mailto:torontomoviesandoutings@hotmail.com) Come for the tunnels. Stay for the laughs. Leave knowing a secret shortcut through downtown that most people still pretend to understand. Toronto has layers. Let’s go explore one of them. 🏙️✨

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. 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. 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 created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
