What is meant by correct breathing?
Unless the science of breathing is properly understood and correctly practised, there is a likelihood of imbalance in breathing, which may result in various types of mental and emotional conflicts and impulsiveness.
Most people breathe incorrectly, using only a small part of their lung capacity. The breathing is then generally shallow, depriving the body of oxygen and prana essential for good health. The first practices taught to pranayama students are preparatory techniques which introduce correct breathing habits. In addition, they help focus the awareness on the breathing process, which is otherwise normally ignored.
