Hi The23rdMan,
Thanks for sharing your experiences.
I had very similar feelings when doing this exercise and it gets stronger as you practice. Soon you may start to feel that as one hand turns at the top or bottom it turns the other for you. It feels exactly as though your hands are magnets that are reversed in polarity and moving in a stream of energy. I think this feeling is why I enjoy the active exercises so much.
I also felt this in the Joining of Yin & Yang the first time I tried SFQ. I think this happened as they were both quite easy to remember and I was able to free my mind and meditate deeply. As you practice more and the motions become automatic, you will start to get similar feelings in each exercise. It is very exhilerating.
My thoughts are that you have tapped into your energy field and there may be a slight imbalance between yin and yang. I had the same feelings at first and as I practiced I eventually felt that both my hands moved smoothly in the energy field through the cycle and had the same force applied evenly throughout.
You can feel when there is balance and when you have done an exercise for long enough. It also helps me greatly to meditate and visualise as I can focus on the sensation and work by touch to a certain extent.
NOTE: When I say practice more, I believe you can achieve everything I have mentioned and more in your next session, even before. Believe in yourself, trust in your master and have no limits. Know that whatever happens is perfect and give thanks.
I would love to hear of your progress in the future if you feel like sharing, it is great to hear of someone having similar results with SFQ.
