Standing in front of the camp fire by the lake. The warmth from the fire transferred to the body. The flow of energy inside of the Ging and Mai is actually the same as the meditation practice. Also is the same as when it rains.
Maybe, the energy just reflects what's happening in the body.
It was a good experience to watch the fire brought the progress of the chi movement inside.
There is so much to learn after observing the energy development inside of our body.
