Yogasana and Pranayama are closely inter-related. An aspirant should master asanas like Padmasana, Siddhasana, Swastikasana and Sukhasana before he begins to practise Pranayama. One can be called the master of a particular asana only when one practises it for three hours without any movement of the body. At the start, it is very difficult to accomplish this. So it is advisable to begin with any asana suitable to oneself him and practise Anuloma-Viloma Pranayama. Gradually,with the help of Pranayama, one will get mastery over that asana. Thus, Pranayama is helpful in getting mastery over asanas.
Yogasanas become much more effective if they are performed with Puraka, Kumbhaka and Rechaka Pranayama in the right proportion. Pranayama is helpful in practising and maintaining asanas. The lungs can be properly expanded and contracted through Yogasanas and Pranayama. Yogasanas and Pranayama supply plenty of oxygen to the lungs and so the body becomes healthy and the mind contented and delightful. Hence, the basic knowledge of Pranayama is of immense help to the students of Yogasana.
