Finding Hope in Chaotic Times (Free Event)
How can a spiritual perspective help us make sense of the times in which we live?
Despite efforts by many well-intentioned people, it seems more true now than ever that the problems humanity is facing sometimes seem to be getting worse not better. Divisions appear to grow deeper day by day, social relationships can feel strained, our institutions often appear unable to meet the needs of the world today, and even the viability of the natural environment around us seems threatened. So in the midst of these turbulent times, where can we turn to for sources of hope? In times of crisis, are there actually new opportunities for a more peaceful, just, and sustainable way of life? How can we help build those new patterns in our communities?
Come join a different kind of conversation โ one that welcomes every perspective in a search for the truths that unite us all โ as we discuss the spiritual perspective offered by the Bahรกโรญ Teachings on how to promote constructive change in these difficult times. Join us for a lively discussion as we explore the role spirituality can play in our efforts to construct a new, more meaningful path forward in the midst of social turmoil.
*โThe world of mankind is in the throes of evolutionary activity indicating the passing of the old conditions and advent of the new.โ* โ Bahรกโรญ Teachings
**\*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.**
Quads & Doubles Volleyball - Competitive BB+/A
Let's get together to play some competitive quads and doubles volleyball.
**COST**: FREE
**Court Type**: Outdoor grass
**Minimum Skill Requirements**: BB+ (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details)
Attention:
1. This event is **NOT on a first come-first serve** basis and players with higher skill level and players who can bring a net/ball will get priority over others on the wait list.
2. Since skill levels are **self-reported**, some new attendees may not meet the expected level. For doubles, we encourage you to choose a partner you can enjoy the game with, and since this a competitive event, it is okay if you make a strong team and win all the games.
3. Each person must help set up and take down one net, leaving some nets unset for latecomers.
4. Please answer all questions, so it's helpful for us to organize the event.

*Systemic constellation* work explores the path of inner freedom and fulfillment by uncovering and releasing trauma. Harrison is honored to be the guest facilitator (standing in for Randy) at the Teal Center for this monthly event. As pointed out on the Teal website the constellation process:
*"...doesnโt just uncover wounds; it reconnects you to inner resourcesโstrength, belonging, dignity, ancestral supportโthat were always present but obscured.*
*From this place, genuine movement becomes possible. The work tends to feel less like โfixingโ and more like remembering who and what you already are, creating conditions for profound healing, clarity, and moving forward."*

Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machineโs?
This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
We encourage audience participation during this event that will be moderated by Chris Slee.

This month's prompt concerns the idea of the โwarrior philosopherโ (seemed appropriate in these times)--that is someone whose understanding of violence, power, and justice is forged through direct experience of war. We are looking at Major General Smedley D. Butler, a highly decorated U.S. Marine raised in a Quaker (pacifist) tradition who later became a prominent critic of American militarism (there is a wonderful biography of Gen. Butler called "Gangsters of Capitalism")
Butler's argument in *War Is a Racket* (1935): that many U.S. interventions were driven less by national defense than by corporate and financial interests, with Butler portraying himself as an enforcer for business and Wall Street. We can consider the moral ambiguity of his insider critiqueโwhether complicity strengthens or undermines credibility and also consider some of the concrete reforms he proposed (e.g., โconscriptโ capital before soldiers, restrict the military to coastal defense, and have only those who fight decide on war).
Butlerโs life arc clearly changed from pacifist upbringing to warrior to antiwar crusaderโand asks whether true understanding of peace requires firsthand knowledge of war, and what that implies about the cost of suffering. So do we need to suffer to understand suffering? Do we have to experience war to appreciate peace? As one more question: in the movie "A Few Good Men" Jack Nicholson's character says that "you have the luxury of not knowing what I know" so do most of us go through life oblivious to real violence and suffering? See you at Drunken Philosophy!
