This book presents the four essential pillars of Chinese energetics aimed at protection from and prevention of common and more serious illnesses:

A healthy, varied and natural diet, which supports the elimination of toxins through the body's outlets via conscious breathing.

The regular practice of Qi Gong, which activates the circulation of blood in the vessels and optimises the energy in the meridians.

The strengthening of the immune defences, of the vital energy of the kidneys and of the Qi through abdominal breathing.

Sound emotional balance in relation to the main organs, through the tree of Zhan Zhuang and Zen Buddhist meditation.

These four preventive methods, the Yang Sheng of the Tao, consist in nourishing the "vital principle" of the human being in accordance with the laws of nature.
