Free In-person Meeting: Unwanted Emotions & Loneliness, How to Get Over Them
This is an in-person meeting.
Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance.
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues.
So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them?
That is what this meeting will be all about.
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.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.

Drunken
This month's prompt concerns the idea of the “warrior philosopher” (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 critique—whether complicity strengthens or undermines credibility and also consider some of the concrete reforms he proposed (e.g., “conscript” capital before soldiers, restrict the military to coastal defense, and have only those who fight decide on war).
Butler’s life arc clearly changed from pacifist upbringing to warrior to antiwar crusader—and 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!

Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machine’s?
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.
Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
