Well person I've met, but say it happened for them when a heart condition they'd had for decades was healed and doctors could find not sign of it. Another might say they believed it was real after their cancer dimished then was gone.
Some are convinced by the sword fingers and growing finger demonstrations.
A part of me would still say, well that's just the power of the mind..... and what's wrong with that, but does that mean there really is a qi?
Well for me, I was sitting in the audience while Master Lin worked on a group of people on stage. I had wanted to go up there and experience his energy, but well there was a stampede and I had no real illness. So I just sat quietly in the audience, close to the stage.
I didn't know SFQ at the time. I spent much of the healing with my eyes closed and relaxing. I don't know why, it just seem the next best thing to do if I wasn't on stage. While I had my eyes closed I saw the flash of a camera and thought how rude and inconsiderate. Later one of the people on stage asked if the person who had taken the picture could send them a copy. The person was informed that no picture had been taken. Master Lin said it had been the qi.
My experience, without a pre-loaded suggestion and confirmed by a other person convinced me, a person with a science background, that qi is more than just positive thinking.
At the time I didn't recognize the significance of this experience for myself.
If you travel the path of SFQ you will have the experience(s) that will solidify your belief.
You are perfection.
