It belongs to the universe. We are all part of the universal ki . Like electricity, ki has plus and minus, positive and negative charges. Ki is as current in amperes. Mind is as power in voltage.
Body is as resistance in ohms.
We must have a healthy body that knows how to relax. This relaxed body becomes a good conductor and ki will flow freely in a cycle from the universe through the body. The mind, through concentration, extends or forces the ki through the body. Like electricity, it will be felt only on contact or when touched. Daily training is needed to develop it.
