Raising Conscious Kids – A Unity Family Experience
At Unity of Columbus, our Youth and Family Ministry nurtures the spiritual growth of children and families through love, joy, and practical spiritual teachings. Each Sunday, children explore timeless spiritual principles through stories, creative activities, music, and group sharing in a safe and welcoming environment.
Our program encourages children to discover their own inner light, express kindness, and develop a personal connection with God. Together, we celebrate diversity, cultivate understanding, and inspire each child to live with purpose and compassion. Parents and families are invited to join in this uplifting journey of learning, laughter, and spiritual connection.

Swap for something new-to-you from others. *The more you bring, the more there is to exchange!*

How Lucky by Will Leitch
Posting this early because seemingly all Sundays in May are holidays or busy! I picked a shorter thriller that's hopefully a fast read/listen.
[Columbus library link to book](https://cml.bibliocommons.com/v2/record/S105C3458940)
Location: Grandview Cafe, *1455 W. 3rd Ave*,
Columbus, OH 43212
[Menu](https://www.grandviewcafe.com/menu)
Book summary:
Daniel leads a rich life in the university town of Athens, Georgia. He's got a couple close friends, a steady paycheck working for a regional airline, and of course, for a few glorious days each Fall, college football tailgates. He considers himself to be a mostly lucky guy -- despite the fact that he's suffered from a debilitating disease since he was a small child, one that has left him unable to speak or to move without a wheelchair. Largely confined to his home, Daniel spends the hours he's not online communicating with irate air travelers observing his neighborhood from his front porch. One young woman passes by so frequently that spotting her out the window has almost become part of his daily routine. Until the day he's almost sure he sees her being kidnapped.

Our meditations guide others to actually experience that energy! xoxo We don't just talk about peace, love and affection, we experience it :)

Tango & Milonga: Practice and Social in Dublin
We practice, dance, and enjoy a BYOB bottle of your favorite wine at the Dublin Ballroom off Sawmill, North, and “milonga” is a social event for tango dancing where dancers socialize. A “*practica*” is an informal social event for tango dancing where dancers focus on practicing the dance; while a “*practilonga*” combines the relaxed atmosphere of a “*practica*” with the format of a “milonga.” We are doing it all!
***Cost is $10 payable to the Teacher.*** *Cost is for the cost of the venue and covers some snacks.* We have had fun doing this event in the past. Please arrive promptly as lessons begin at 2pm. Don't worry about bringing a partner as there will be others at the event from outside the group that: a) might have a clue and b) won't step on your toes.
The event is BYOB (similar to our Salsa events), so bring your favorite and a wine glass. We will likely find a place for dinner and drinks after the dance.
Investing & Personal Finance Meeting
If you are interested in selecting investment choices for your 401(k) or other workplace savings plan, minimizing your income tax liability, or identifying the most effective investments for your brokerage account, we are the group for you.
We are a local chapter of Bogleheads, whose investment strategy can be found here:

Or you can peruse the Boglehead forum here:

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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.

Take Control Of Your Life, Freedom From Negative Thoughts & Irrational Emotions
Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences.
Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future.
What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs.
At this free local Meetup event we will talk about:
* What causes grief, anxiety and depression to become chronic.
* Is it possible to regain your joy and happiness even after traumatic experiences?
* How to break away from negativity and focus on the future
* What are the steps to take to get control of your mind and your emotions?
Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home.
Let's explore safe, effective solutions for healing from traumatic experiences.
Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there.
This group is sponsored by the Dianetics & Scientology Life Improvement Center.
