Yes, you're right about the varied vibrations. I'm glad you mentioned that because it reminds me to use my intuition versus my head. For example, I attended a workshop with 30 people who were complete strangers to me but the room was filled with a very positive energy. Then, a woman sat next to me and she had a weird vibration. I felt it and didn't say anything. She got up and moved a seat away from me. I overheard her talking to another person and she was quite negative. I thought to myself, "Oh, she must not like me. But maybe that is a good thing."
Another woman across the room had bloodshot eyes and seemed very, very down. I felt sorry for her. Some of the attendees were just bubbly and upbeat with a very playful attitude as though this were all a fun game. Others more grounded but were open to expanding awareness.
This was a class and not a true development circle though.
I had walked into shops and classes where the vibration was dark and heavy. There is a well-known center in the next city and I attended a fair there once. While I was drawn to development, I cannot make myself go to that location. I get this distinct feeling that the place is filled with many errant spirits roaming around. I am not afraid. They are not necessarily dark or harmful. But still, I must not resonate with that location.
I would be very interested in an virtual circle. Can you share some details? You can PM me if you like.
