Pranayama is control and extension of Breath". "Prana" is Breath or vital energy in the body. On subtle levels prana represents the pranic energy responsible for life or life force, and "ayama" means control. So Pranayama is "Control of Breath".
One can control the rhythms of pranic energy with pranayama and achieve healthy body and mind.
Patanjali in his text of Yoga Sutras mentioned pranayama as means of attaining higher states of awareness, he mentions the holding of breath as important practice of reaching Samadhi. In Patanjali's "Ashtanga Yoga", Pranayama appears at the fourth stage. This means unless one observes Yama-Niyama and does Asanas well, he cannot reach this fourth stage.
Hatha Yoga also talks about 8 types of pranayama which will make the body and mind healthy.
As people have attraction towards Yogasanas, similarly they have attraction to Pranayama. The process of Pranayama is concerned with the breathing, the indicator of life. And therefore, if it is done wrongly, it may do harm to the person.This fear dissuades many from taking up Pranayama.
The second reason for not taking is the absence of teachers who can teach it scientifically. However, it is true that if one does Pranayama unscientifically, without proper guidance, one certainly suffers. But it does not mean that it is such a difficult process, that it cannot be done by a common man. On the contrary, if it is learnt and practiced under an expert's guidance, one learns soon and experiences the wonderful and even unimaginable benefits.
We can say pranayam as the nanotechnology of medical science which has highly therapuetic results in every aspect of health either physical ,mental,social or spiritual aspect and we use pranayam as the main tool of our special programmes.
Actual Pranayama means the holding up of the process of exhaling and inhaling.
