The Theory of Yin and Yang

1) Theory of Yin and Yang

   Ancient experts recognized natural phenomenon and physical matter into separate entities Yin and Yang.   In nature, duality of life force(matter and phenomenon) coexist and that is represented by the symbol of water and fire.   Ying and Yang can siimply explained as 24 hours in a day which is divided into 'day'(Yang = fire) and 'night'(Yin = water) or in one year winter(Yin = water) and summer(Yang = fire).   There are more 'states' that are inbetween Yin and Yang because the energy changes state in alternating fashion.   If we continue our anology of 'a day' we must realize that there is a 'morning'(middle of Yin and Yang) that starts the cycle, 'noon'(Yang), 'sunset'(middle of Ying and Yang) and, finally 'night'(Yin).
   The transformation  of states between Yin and Yang, opposition of Yin and Yang, to the interdependenance of Yin and Yang, mutual of Yin and Yang, to inter-transformation of Yin and Yang is translated into the human body as Qi(aka 'chi' , Yang) and blood, fluid(Yin), if the balance is broken the human body could develop diseases and ailments.   The treatments using acupuncture, moxa, cupping and other methods are used to bring the body into balance to heal the body.
