Diana;
How I think this would fit into Qigong healing practise is just like how Master Lin mentioned the musician with the energetic flock of birds that interfered with his songwriting. Or the Rose who helped the lady resolve her breast cancer. In both cases he "talked" to them to cure the problem.
It is also used in "Talking " to the Masters and requesting help.
As a side story I always noticed that Dance Instructors always went Dancing on their off time because they loved to dance. Maybe "talkers" go off and talk for the same reason.
