For a common man, pranayama is nothing but a breathing technique which helps in stress relief and relaxation. But for people who know the benefits of pranayama, it is a science of inhalation and exhalation that brings the involuntary action under human control. The word pranayama is derived from two words – Prana and Ayama. According to practitioners of Yoga, prana is the universal energy or life force which is omnipresent. It is also considered to be cosmic energy that connects all the elements of the universe together. Ayama is the technique of guiding, stimulating and giving rhythm to this energy force within our body.
