We gather to help each other integrate our journeys, find "the others", and or seek wisdom about altered states of consciousness. Arrive ready to share honestly, openly, and from the heart. Bring your insights from journeys to unpack or your questions about plant medicines and psychedelic experiences to ask the more experienced journeyers. At 7 pm we will do a short grounding exercise and a brief check-in/ice breaker. At 7:15 pm we will begin the integration circle with honest and open processing of psychedelic experiences. Your facilitators are trained in psychedelic integration and or other coaching/facilitation modalities but we are not mental health professionals, we are community members called to service in mutuality.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in 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 & Scientology life improvement center.
