Hi Iam2,
I just wanted to clearify, that I didn't have an 'experience' of heat, in the sense of it appearing due to the phone session. Heat, or warmth, for me is a constant with qiqong exercise. I was in a sitting position, which for me generates warmth. Master Lin's guidance, allowed me to focus on what was there, and amplify it, or draw and focus it to a place, just like bringing all ones energy work to the lower dan tien , spinning it, and closing. This warmth , for me, doesn't have to be created, it is already there, hence my newer perspective of utilizing that, and how well I felt its connection to smoke. What's that saying,,,,where there's smoke , there's fire?? something like that!!
love,
gallen
