This world is one of conflicting benefits, of conflicting interests and conflicting ideas. If there were not a balance everything would go topsy-turvy. The body works because there is balance in it. Two contradictory streams of energy are flowing within it. Pran or breath is contradictory to apan and vice versa. Man lives because of the balance between the two. There are many glands in the body. They have different functions to perform and yet there is a mutual understanding and balance between them. As long as there is balance, the body is fine and once this balance is lost, trouble begins.
Balance is the bridge between two opposing claims. It prevents a clash between opposites. Anekanta has clearly explained balance.
