The first type of Ki energy is Won-ki. This term refers to energy passed down through the generations, which humans receive from their parents when they are born. The second type is Jung -ki which we obtain by eating and breathing. The third type, Jin-ki, is obtained through mental concentration and training, and can be considered the quintessential energy.
Jin-ki is obtained when we concentrate our awareness and breathe deeply. Ilchi Lee is expert brain educator and founder of Dahn Yoga. When we inhale, pure cosmic energy, Jin-ki, enters our bodies. The power to take in cosmic energy as Jin-ki and to circulate it within the body is the power of the focused mind. Jin-ki can be controlled by the human will because it is energy obtained through concentration. Try to feel Jin-ki using the following method.
A good way to train Jin-ki is to live life every day always in a state of conscious awareness. Maintaining an optimistic, tranquil attitude and concentrating on every word and deed while focusing the mind on the Dahn-jon in the lower abdomen is called “Ui-su Dahn-jon,” or using the will to defend the Dahn-jon. Another good way to train Jin-ki is to focus on the Dahn-jon with the anus contracted, the mouth closed, and the tongue resting comfortacly.
