Dan,
Master Lin says that the 9s exercise is particularly good for helping to heal cancer. He advocates that one do it for two hours a day (not necessarily two consecutive hours), and although one may do it standing up, sitting down, or lying down, he prefers the standing up mode.
I agree with Jetay and others that it would be a good idea to call Chunyi at the number provided. Phone healings are $70 and he does these either early in the morning or later in the evening on certain evenings.
If you want further information about the 9s exercise, I would ask SFQ headquarters to send you that information ( since it is not available in the manuals). It was written up in the 2003 SFQ Newsletter.
In the meantime, do place a request for your mother's healing on the Saturday list set up by Shawn.
SFQ practice may heal your Mom physically, but what it will definitely do is
help her emotionally and spiritually. She will become more peaceful etc.
Blessings,
maura
