### Bhagavad Gita Study Group **Planned Start Date:** Wednesday, March 11, 2026 **Wednesdays\, 7:00 PM \- 9:00 PM \| Ongoing** **Where:** Toronto Theosophical Society, 792 Glencairn Ave, Toronto, ON **Format:** In-person (Zoom considered for special circumstances) **Main Text (free PDF):** *[Bhagavad-Gītā As It Is](https://www.prabhupada-books.de/pdf/Bhagavad-gita-As-It-Is.pdf)* by **H.D.G. Abhay Charanaravinda Bhaktivedanta Swami Prabhupada** Physical books are available in exchange for donation. This weekly study group offers an opportunity to explore the **Bhagavad Gita**, one of the foundational texts of **Vedic philosophy**, through sustained reading, reflection, and thoughtful dialogue. The Bhagavad Gita addresses fundamental questions of **consciousness, duty, freedom**, and **the nature of reality**. Presented as a dialogue between the warrior Arjuna and Sri Krishna, it offers insight into paths of **knowledge, devotion**, and **action**—and examines how these integrate within human life and spiritual development. The approach will be: * Textual study combined with open discussion and inquiry * Exploration of Vedic philosophy, cosmology, and psychology * Question-and-answer format to support understanding * A complete picture of the cultural and spiritual context This group is suitable for: * Those new to the Bhagavad Gita or Vedic philosophy * Students continuing their study of Eastern spiritual traditions * Anyone interested in consciousness, ethics, and the structure of reality * Participants seeking grounded philosophical inquiry alongside spiritual exploration **No prior background is required**—only openness, curiosity, and a willingness to engage thoughtfully with the material. *** **About the Teacher** **Radhikatma Prabhu** is a disciple in the **Brahma Sampradaya**, one of four authorized Vedic lineages. He received second-level initiation from his spiritual master, **Tamal Krishna Goswami**, who was a direct disciple of **H.D.G.A.C. Bhaktivedanta Swami Prabhupada**, the scholar and teacher who brought Vedic knowledge to the Western world and founded the International Society for Krishna Consciousness (ISKCON). Radhikatma Prabhu spent many years studying and practicing in **Israel, Europe and India**, where he received training in Vedic rituals and holds the traditional status of **Brahmin**. During his formation, he worked closely with Tamal Krishna Goswami, who in addition to his spiritual leadership was an accomplished academic, holding a **B.A. in Religious Studies** and a **Ph.D. from Cambridge University**, where he authored nine volumes of scholarly work. This period of close service deepened Radhikatma Prabhu's understanding of both the **devotional and philosophical dimensions** of the tradition. He brings to this study group both the authenticity of traditional lineage transmission and the ability to make these teachings **accessible and relevant** to contemporary students seeking to understand Vedic philosophy and apply it.

**NO PHILOSOPHY EXPERTISE REQUIRED!** **🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 **📓 HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/B7LyJIeBlaH5VtXkMJTTph?mode=gi_t), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 19:30-19:45 - People arrive and chat, get to know each other before the official start. * 19:45-19:55 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 19:55-21:15 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 21:15-21:30 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo. * 21:30 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other. **🧧PRICING?** Practical Philosophy is operated entirely on voluntary donations! If we are meeting in a café, buy a beverage! Donations are 100% voluntary, but they help us to bring the gift of deep conversation to people around the world. If you'd like to support, you can [donate here](https://www.zeffy.com/en-CA/donation-form/donate-to-practical-philosophy)! (Practical Philosophy is a registered Canadian charity) **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** **🗣** “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * **Do I need to study or read anything to attend?** No preparation is necessary. This isn’t a study of other thinkers. We want to know what you think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it. * **Is there a specific philosophy that Practical Philosophy is focused on?** The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * **Is it mostly men that attend?** Surprisingly, no! Although often, philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * **Can I come alone?** Of course you can, we encourage it :) * **Can I be late?** Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * **Where do you meet?** The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/B7LyJIeBlaH5VtXkMJTTph?mode=gi_t) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent.

Struggling with motivation and focus as you hammer away on your manuscript at home? Want to join a community of writers as we embrace the joys and pains (mostly pains) of writing together? Bring your laptop, pen & paper, old-school typewriter, or futuristic writing gadget, and join an enthusiastic community of science fiction and fantasy writers as we work on our current projects in the same space. The format will be similar to our online writing sprints: 30-minute blocks of focused, quiet writing time (the sprints), interspersed with breaks where we can chat, ask questions, and share our writing experiences.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/xwjDdVSw3E **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

[Summary] This meetup is for those who are interested in code, web development, design, cloud, or AI. All levels are welcome, so feel free to bring your laptop and discuss what you are working on or what you are learning. You can share your projects and ideas with other participants freely. There are outlets and WiFi, drinks are about $5 for tea, they take card only. [Price] Attendance is FREE. But you need to buy something from the venue. [Policies] \- We do not tolerate harassment of our members \- We remind users that that this meetup is intended for networking and hobby development\, and any attempts at using this meetup event as a dating platform will not be not be tolerated Further information: https://torontostack.exchange/

### Thursday Evening Discussion Group **In\-Person \| Starts at 8:00 PM \(Doors open at 7:30 PM\) \| Drop\-In** **Starting material:** *[Network of Thought](https://www.holybooks.com/wp-content/uploads/Network-of-Thought-Krishnamurti-ebook.pdf)* by **Jiddu Krishnamurti** This weekly discussion group offers a reflective and open space to explore themes of **mysticism, spirituality, and inner transformation** through selected writings and talks by Jiddu Krishnamurti, Annie Besant, Alice Bailey, and other thinkers whose work invites deep **inquiry into consciousness, freedom, truth,** and **the nature of self-understanding**. Rather than promoting a particular belief system, the group emphasizes **shared reading, thoughtful reflection, and respectful dialogue**. Participants are welcome to engage at their own pace—whether through listening, contemplation, or open discussion. While there is **no requirement to commit before attending**, *the intention is to gradually build a group of participants who are interested in returning regularly and engaging sincerely with the material* and the group process. Newcomers are very welcome, and those who feel drawn to ongoing study are warmly encouraged to continue attending. This is a **drop-in group**, and no prior background or preparation is required. **All are welcome.** Come as you are, reflect together, and take part in a spirit of openness and mutual respect.

This panel brings together identity leaders to challenge today’s assumptions, debate what’s hype versus real architectural shift, and explore where existing identity guidance breaks when agents start acting on our behalf. Through sharp, opinion-led questions on delegation, standards, continuous decisioning, and auditability, panelists will surface the principles and industry changes that will matter most in the next 12–24 months. **7:30pm -** Network **8pm -** Event and attendees exit venue Have a great day, An

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8.

Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9
