Technique: Sit comfortably on a chair, sofa or easy-chair. Draw the air through both nostrils, as long as comfortable. Retain as long as comfortable. Repeat your Ishta Mantra or 'OM' while retaining the breath. Then exhale as long as comfortable. You need not observe any ratio between the inhalation, exhalation and retention; but let the inhalation and exhalation be deep and full.
Benefit: The benefits of this Pranayama are incalculable. All the muscles are relaxed. All the nerves are toned. Rhythm and harmony are established in the entire being. Mind is calmed. Circulation is promoted. An inexpressible peace and bliss come to reign within you.
You can do it in the morning while lying in bed. Your mind will become alert for commencing Japa and Dhyana. You can do it when the mind is about to lose balance on account of the setting in of lust, anger or other evil Vrittis; the mind will be filled with a great power that will prevent the evil Vrittis from disturbing it. You can do it just before commencing your study; the mind will be concentrated easily and what you study will be indelibly impressed in your mind. You can do it during your office-work; you will get new strength every time and you will never be tired. When you return home from the office you can practise this Pranayama and you will be recharged with fresh energy.
The greatest advantage is that once you start doing it you will do it very often; and your mind can never find an excuse for not practising this Ati-Sukha-Purvaka Pranayama, very easy and comfortable Pranayama which has all the advantages of Pranayama, without its 'rules and regulations'. Do it from now without fail.
