Yin and Yang-In Acupuncture

As per acupuncture,we can classify all the things in the world into 2 groups. One is YIN, and the another one is YANG.These two will behave like a magnetic nature,and will act on opposite side of each other.Both are negative to each other,but they are not without each other.If Yin gets increases, Yang decreases.These Yin & Yang are also in human body.Both of this should equal in our body.If they are equal in our body ,that indicates that our body is very healthy.If Yin increases,and Yang decreases there will be a loss of balance in our body,and that leads to any disease depends upon the condition of our body.When one dominates fully on the other, death occurs to human body.
