JingQiShen are the three treasures in Daoist internal arts that one must constant nurture, cultivate, and balance for a long and healthy life. These three compliment and rely on eachother–if one is weak, the others will suffer, advancing age and increasing the likelihood of disease and sickness.
Jing (精): In English this Chinese term is known as essence. It’s a physical matter that is believed to be stored in the kidneys (yin in nature, apart of the water cycle). It flows throughout your body to keep it strong, healthy and young. It’s the primordial energy given to you by your mother and father. It helps create marrow and semen and aids in the development of bones, hair and teeth. As you age you “use up” your jing. It is important to understand the seven desires and six emotions as these will hasten the loss of Jing resulting in physical decay (i.e. hair loss/greying; weak bones/connective tissue; teeth issues; dull mind; etc). If you Jing completely depletes your body dies.
Qi (氣): In this reference Qi is defined as the life force that enables your body to move and focus. When your body is strong (strong jing) your Qi will be abundant and circulate freely. Qi is connected to the blood and air and thus thought to be the result of lungs and spleen. Qi is also associated with Yang and Fire cycle. It circulates through your 12 meridians and 100 vessels. If there is an imbalance, blockage or disruption then one can get sick, injured, or die. When Qi strongly circulates a person’s fu organs will be nourished and healthy, they will move energetically and their si shou will be fully developed and strong.
Shen (神) can de defined as spirit. It is the energy behind mental functions and spiritual awareness. To develop a strong shen one must have strong qi and solid jing. Shen is housed in the heart and is another reason a person must conquer their emotions and desires, becoming centered and balanced. To be centered and calm a person gains the ability to convert and consolidate shen in their Upper Dan Tian. Shen will primarily be observed through the eyes (yangshen 眼神), through a strong and radiant gaze.
Overall the three treasures nourish eachother and are developed or used mutually. A strong JingQiShen creates a strong and healthy ming (life). If a person develops and cultivates these treasures they will slow aging (cellular decay is slowed), will have a tranquil peace of mind, and have abundant vitality. Through Daoist concepts they may be able to develop a connection back to the void and expanded consciousness. Now this is easily written but to truly have a strong JingQiShen one must live a regimented lifestyle often antagonist to work and relationships.
Can I not have a strong JingQiShen then? Yes, not as strong as the monks and martial artists of old but still strong enough to live a healthy, mobile, and happy life. You must guard your treasures, nourish them, and cultivate them. Do not let your desires scrape your bones, your procrastination strip away your youthfulness, and your idleness rob you of your mind.
Consistent (Daily) and focused practice will allow gains to slowly and surely be made. Over time, this compounds, and resulting in real and recognizable gains in strength, health, and mental clarity. Again, the ideals are easy to discuss and understand but true discipleship in this method takes dedication and patience.
