### 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.

**This is a ticketed event. Please register at [this link](https://luma.com/n5d2q50u).** ​The Platonic Representation Hypothesis (Huh et al., 2024) proposes that neural networks are converging toward a shared statistical model of objective reality, offering a Platonic explanation for the growing representational similarity observed across models of different architectures, datasets, and modalities. In this talk, Robert Adragna argues that such convergence is computationally intractable in practice. Truly representing reality would require models to recognize the same real-world concept across all its possible appearances — a form of robustness that theoretical and empirical work suggests is infeasible to achieve at scale. He proposes an alternative account: representational convergence reflects shared structural assumptions embedded in training data, not the discovery of objective reality. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

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.

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!
