This oscillation continues, till everything is well balanced. Our lives are a series of swings from too positive to too negative. This is because our actions and thoughts are imbalanced. Knowledge of this law helps to bring back the balance and harmony in our daily lives. It becomes smooth and peaceful instead of violent swings of polarities.
