February 13, 2014: “kaya nagara madhythu marutha kshithi palakaha”. In the city of our body, there is the king air. His majesty the air is the king emperor of our body. Ever since the child comes out of the womb till the man dies, respiration goes on incessantly knowingly or unknowingly. Breathing in air is called Inspiration(Inhalation) and breathing out of air is called expiration(Exhalation). Inspiration is Niswasa and expiration is Praswasa.
