Thank you all for your comments. I reviewed the manual and of course you are right. Palms up for low blood pressure. I've always meditated in the Japanese posture - probably because of my many years with NSA/SGI - and it's soooooo much more comfortable than crosslegged.
My symptoms were continuing 24/7 there for awhile, but mostly disappeared when I cut way back on the amount of time I spent doing SFQ. I've only brought up the blood pressure thing because I just recently discovered what the problem was and hoped others might learn from my experience. If you feel lightheaded, dizzy, have rapid pulse, heart palpitations and/or shortness of breath during or after SFQ, a drop in blood pressure could be involved.
When I found out about the blood pressure, I decided to try adding a positive reinforcement during the harvesting of the Qi - "blood pressure going up!!." This actually seems to help...lol.
Gallen, please tell me what "reverse breathing" is.
Peace and love,
Susan
