The purpose of the practice is to develop one’s body and mind to the ultimate potential.

The essence of life force in lower Danjeon (Jung, 정, 精) representing the physical force and is located at the center of lower abdomen. The essence of life force in the lower Danjeon nourishes the upper Danjeon (Ki, 기, 氣) representing spiritual/intellectual force and is located at the brain. The life force in the upper Danjeon nourishes the life force in the middle Danjeon (Sin, 신, 神) representing mental/mind-will force and is located at heart. 

Sun Do is a practice to raise the life force in lower Danjeon thereby enriching the upper and middle Danjeons.

This process is beautifully explained by the Grand Master: the life force in the lower Danjeon can be compared to the wax/wick of candle; and the life force in the upper Danjeon can be compared to the flame of the candle; and the life force in the middle Danjeon can be compared to the light of candle. A bigger candle provides bigger flame and bigger light.

This Jung (정, 精), Ki (기, 氣), Sin (신, 神) 3 danjeon practice is can be found only in Sun Do. No other oriental philosophy or medicine system explains the concepts, functionality and the way of developing these 3 danjeons as Sun Do does.

Through life long practice, Sun Do aims to acquire utmost health and strength in body and mind, noblest virtue of human nature and spiritual enlightenment solidified in body and mind.

Sun Do practice utilizes the universal energy to attain a healthy body and mind and to achieve the goal of our life. The goal of Sun Do is to participate in the universal rule of nature so that we can co-exist in harmony with nature.
