Some of the most challenging places to be LGBTQ+ are in Africa -- but that doesn't stop gorgeous queer expression there. The National Museum of African Art offers a beautiful collection of 60 works by LGBTQ+ African artists. Join us, and find a new favorite queer artist from Africa! MEET AT: Outside the main entrance to the National Museum of African Art. It is inside the gardens behind the big red stone Smithsonian Castle and looks like the picture above. Look for Molly with the rainbow LAL sign. COST: FREE! NEAREST METRO: Smithsonian **Exhibition description:** Artists’ voices are central to this exhibition, which is based on years of close collaboration and dialogue with African visual art practitioners who claim belonging in the LGBTQ+ community, however they define those terms. They are united by a simple, shared declaration: **We are here and always have been and will be.** The exhibition is part of a larger research initiative, the Here Project, that seeks to document these voices. The artists in the Project practice across the entirety of the African continent and its global diaspora, using their work to speak their truths. Inviting us into their worlds, they share complex stories of openly claiming their identities, their histories, and their place. While their experiences are unique to them, they address issues that unite us all: the importance of family, of spirit, of standing up for oneself and others, of imagining the future, of making intimate connections, of finding belonging, of embracing potential, and above all, of experiencing joy. *Here* is based on years of close collaboration and dialogue with these artists and their communities. Through their art, they invite us into their worlds, and share complex stories of openly claiming their identities, their histories, and their place. *Here* is in the largest exhibition on this subject to date, with nearly 60 artworks, demonstrating how they are a part of a larger story of African art history.

Our April book is "The Highly Sensitive Person" by Elaine Aron. Join us for exploring the fascinating trait of high sensitivity, in Dr. Aron's pioneering book! Researchers believe approximately 20% of the human population has this trait that affects every dimension of a person's life, including mental and physical health, relationships, and more. Curious if you are highly sensitive? Dr. Aron's Self-Test Questionnaire is available on her website. [Are You Highly Sensitive?](https://hsperson.com/test/highly-sensitive-test/) Also, there's recently been a documentary on the topic of high sensitivity, where Dr. Aron discusses the trait. Here is a trailer. The full movie is available for free on YouTube. [Sensitive: The Untold Story](https://www.youtube.com/watch?v=nXlOyGuvfVE) We'll start the meeting with each person sharing their name and one thing they found interesting or helpful about the book, then have open discussion. Here is the Amazon description of the book: "ARE YOU A HIGHLY SENSITIVE PERSON? Do you have a keen imagination and vivid dreams? Is time alone each day as essential to you as food and water? Are you noted for your empathy? Your conscientiousness? Do noise and confusion quickly overwhelm you? If your answers are yes, you may be a highly sensitive person (HSP) and Dr. Elaine Aron’s The Highly Sensitive Person is the life-changing guide you’ll want in your toolbox. Over twenty percent of people have this amazing, innate trait. Maybe you are one of them. A similar percentage is found in over 100 species, because high sensitivity is a survival strategy. It is also a way of life for HSPs. In this 25th anniversary edition of the groundbreaking classic, Dr. Elaine Aron, a research and clinical psychologist as well as an HSP herself, helps you grasp the reality of your wonderful trait, understand your past in the light of it, and make the most of it in your future. Drawing on her many years of study and face-to-face time spent with thousands of HSPs, she explains the changes you will need to make in order to lead a fuller, richer life. Along with a new Author’s Note, the latest scientific research, and a fresh discussion of anti-depressants, this edition of The Highly Sensitive Person is more essential than ever for creating the sense of self-worth and empowerment every HSP deserves and our planet needs."

Philosophers, religionists, thinkers and psychologists have long debated whether we are born good, evil or full of sin – or whether we’re all blank slates just waiting to be filled in but with no inherent potential one way or the other. But what if we are actually created to be noble? How might that change the way we look at ourselves? What about others? At children? And the world? The world around us often seems to be telling us that we are unworthy of love or of excellence, that we as human beings are somehow inherently bad – or at least selfish in our motivations – and that this needs to be controlled. But what if we viewed ourselves and others as being born with inherent nobility just waiting to be realized? Is it possible that much of the negativity we see in the world today isn’t because people are inherently bad but that our inherent “goodness” and nobility is not being recognized and nurtured? What role does spirituality potentially play in this? How can a more spiritual perspective enable us to find reasons for hope and inspire us to act, to channel our unique strengths towards creating a world that reflects and nurtures our best selves? Can seeing the nobility in ourselves cause us to recognize and uplift the nobility in others, help us overcome challenges and forge a path towards a brighter future? Come join a different kind of conversation – one that welcomes every perspective in a search for the underlying truths that unite us all – as we discuss the spiritual perspectives offered by the Bahá’í Teachings to deepen our understanding of human nature and the nobility within each of us. Join us for a lively discussion as we explore the role each of us can play in transforming our communities, in building a spiritually dignified world where each of us can thrive. *“...Noble have I created thee, yet thou hast abased thyself. Rise then unto that for which thou wast created.”* – Bahá’í Teachings **\*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.**

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
