Usually translated as “essence,” Jing can also be called Jing Qi. It is thought of as a highly potent essence that is transmitted from parent to child, and is thus also called the “congenital root” or “congenital Qi.” A person begins life with a finite amount of Jing and can consume or conserve the Jing through various activities. Jing Qi is one of the three sources for the formation of Qi in the human body, along with Gu Qi and Qing Qi. Jing is stored in the Kidney.
