The life energy (Qi) is in everything and penetrates everything. Out of this power, everything arises and transforms as well. Qi is matter, energy or information, in certain combinations it also shows itself as synthesis of those conditions. It is a oneness out of complementary natural power, which are called Yin and Yang in Chinese. The equilibrium of Yin and Yang plays a central role in our good health and being.
The Qi flows in energy paths through the body, which are also known as meridians (chin.: may). The existent amount of the Qi, and its state, influence our bodily, mental and spiritual health. And corresponding the way as well, how we live as individual and social being.
Scientists have long been preoccupied with the phenomenon Qi.
Despite its noticed effect there is no internationally accepted evidence for its existence. To emblaze the meaning of Qi in all of its facets is so challenging as to want to explain life itself. In both cases you can only experience/live and feel it, to get little by little your own picture of it.
