Pranayama "Pranayama is control 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. Hatha Yoga also talks about 8 types of pranayama which will make the body and mind healthy.

Five types of prana are responsible for various pranic activities in the body, they are Prana, Apana, Vyan, Udana & Samana. Out of these Prana and Apana are most important. Prana is upward flowing and Apana is downward flowing. Practice of Pranayama achieves the balance in the activities of these pranas, which results in healthy body and mind.

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 its unpopularity 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.

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. Even the Asanas discussed here are presented in their preliminary form. Therefore, for doing Pranayama, it is not enough to have done the Asanas as mentioned here. Even after learning these Asanas and having practiced them, one needs some preparation before actually taking up Pranayama. And an attempt is made to discuss that preparation. Actual Pranayama means the holding up of the process of exhaling and inhaling. And it is not possible to discuss or guide this serious aspect of Yogabhyasa in preliminary discussion. Therefore, as the preliminary exercises are discussed and which are to be done before the actual beginning of the Asanas: similarly, for Pranayama too, the preliminary exercises of breathing are designed and only this part is going to be discussed here.

Before examining the exercises of breathing it is necessary to understand the process of breathing. The breathing process chiefly involves two activities, viz., inhaling and exhaling. Of these the former is called "Puraka" and the latter "Rechaka"' in Yogashastra. These two activities continue non-stop right from the birth to the death of a person. The state when these two activities are made to halt is given the name "Kumbhaka" in Yoga Studies. The halt after inhaling, i.e., Puraka is called "Abhyantara Kumbhaka" and after exhaling, i.e. rechaka. It is called "Bahya Kumbhaka". Two more types of Kumbhaka are mentioned. But instead of talking of them in detail, let us turn to the process of breathing.

According to the speed of breathing, it is divided into three parts:

• The smooth breathing that continues naturally without any effort (Quiet Breathing)
• The protracted breathing which is caused by deliberate slowing down of the breathing (Deep Breathing)
• The quick breathing which is caused by deliberate increase in the speed of breathing (Fast Breathing)
