A personal experience.
For a couple of years, back about the turn of the century, I presented the breakfast show on a community radio station. One morning the next presenter had two aboriginal guests who had come to talk about their culture and who had also brought along a didgeridoo. I asked if I could stay.
As the man played I felt a remarkably strong vibration in my solar plexus, said to be the location of the Manipura chakra.
When we went to a commercial break I said to the man, "You have no idea where that music hit me." He grinned, reached across to touch my solar plexus, and said, "It hit you right there."
He knew.
That man had an uncanny ability and he was the model for Johnno in my novel. He also made me a shield like those Johnno gave his friends. It's hanging on the wall in front of my laptop. Virginia, you can actually feel the energy from it. I'll add a picture of it below.
