Iam2 and Alex - Thank you so much for your replies. I gain so much energy and insight just from reading the postings in this site. I am working with your suggestions. We are not heating with wood, but I do have several environmental sensitivities so possibly this is a factor. I will work at not "judging" the feeling of dizziness and try to just experience it. I find the breathing difficult to I'm sure this is a factor. My breath seems to either be shallow or if I try to breathe deeply, it comes too quickly. If i lengthen the expiration then I feel like I can't slow down the inspiration. Obviously I need to work on this. My worst episode of pronlonged dizzines (I'm not sure that's the right word - more like "off balance") was when I did the Small Universe and I felt so good that I let the tape run and did Self -Concentration right after. That was the first time that I was able to really step aside and go into the emptiness. While this was happening I did notice that my chest felt heavy as if I had a weight on my chest. I felt a little fearful but trusted in my master's energy to watch over me. It was an amazing experience but when I got up I felt so off balance and it has persisted. Is there a problem with doing the 2 sitting mediatations together? Just wondering if that was part of my problem.
Thanks for your help.
