dan2004, Jetay has given you most of the information you've asked for, and it's all very valuable.
You asked does it work, and what you can do. I would say that yes qigong and similar messages healing work as well. The keys to success are outlined in the SFQ courses.
It would be foolish for me to try and teach the material on this forum. However, I can give some basic ideas you can use in a prayer - like meditation. Don't come from a place of anger or desperation. Feel strong love for yourself and your mom. Feel completely relaxed physically and mentally, wrapped in your and universal (god if you like) love. Ask for help from god or whomever you believe will answer, to help in the healing . Then think positive thoughts. Either see the problem (in SFQ the qi in the wrong place) leaving. Continue the love and positive thoughts until you see your Mom completely healthy.
How quickly or in what fashion this will manifest is not predictable. Be ready to notice improvement, but do not label or judge the results.
Lastly, things like SFQ are not a pop a miracle pill and then your done. Yes, sometimes is does work like that but for the most part it about how much time you spend in the love and the intensity of the love experienced, which moves one energy towards a freely flowing and balance life.
As a reminder, use the weekly healing group sessions.
You are perfection, as is your Mom.
