I did not read the post, and yet I will say that the SFQ Small Universe is safe. I have practices it for a long time and only ever had good results.
I have met other people who have heard about bad experiences with qigong. The one thought that always comes to mind when I hear these stories is that the energy goes where the mind goes. So go with love and expectations of good results, which is the core of SFQ.
You are perfection,
