Most precious of them is Jing. It is the essence of all vitality of human. Part of it is inherited from parents (DNA) and the rest is aquired from very slow process of refinement of digesting food and breathing air. It is the most concentrated vital substance which is crucial for all living processes. All other substances, like blood, marrow, brain tissue or bones have their source in jing. Jing is stored in kidneys. To form one drop of blood it is necessary to digest about 20 times more food. To form one drop of jing about 40-50 drops of blood is required. Although energy which controls the vital processes (qi) and form thoughts (shen) comes from transformation of jing.
Guess what is the main ingredient of semen? Exactly - Jing. It has the power to bring life. But what gives life, that takes life. Each ejaculation depletes man of tons of vitality. Frequent ejaculations lead to jing deficiency. What are the effects?
