Prana

 

The Vedic texts state that all living entities are sustained by the life-giving force called Prana. The concept plays a central role in ayurveda and yoga and their holistic view of life.

According to Ayurveda, prana emanates from the sun. It flows through the bodies of living beings through a system of subtle pathways (nadis). We experience prana as breath, but it also exists in blood. Prana is most concentrated in reproductive fluids.

Ayurvedic texts classify prana into five subdivisions – the currents that energize and sustain the body’s physiological processes:

  • The air entering the nose is Prana; it governs the functioning of the heart and circulatory system.
  • The air evacuated from the rectum is Apana, that which removes waste products from the lungs and excretory system.
  • Samana is the air responsible for metabolism and the functioning of the digestive system.
  • Udana flows through the throat. It regulates the vocal chords and the conscious ability to produce the varied sounds of speech, laughter, crying and singing, as the situation demands.
  • Vyana circulates throughout the body and controls voluntary muscular activity.

 

Yoga scriptures break down prana into five more sub-categories responsible for various bodily functions:

  • Naga is the air that regulates burping.
  • Kurma is the upaprana that controls contracting movements e.g. blinking.
  • Krikala is the upaprana that governs sneezing.
  • Devadatta controls yawning.
  • Dhananjaya controls the functioning of heart valves.

Pranayama – the specialized yogic technique of deep breathing – is practiced to control the flow of these currents in the body, so as to enhance the vitality of both body and mind.
