Pranayama During Meditation
If you do concentration and meditation, Pranayama comes by itself. The breath becomes slower and slower. You will practise this Pranayama daily unconsciously. When you are reading a sensational story-book or when you are solving a mathematical problem, your mind is really very much absorbed in the subject-matter. If you closely watch your breath on these occasions, you will find that the breath has become very, very slow. When you see a tragical story being enacted in the theatre or a film-show, when you hear a very sad striking news or some glad tidings, when you shed tears either of joy or sorrow, or burst into laughter, the breath is slackened<197>Pranayama comes by itself. In those Yogic students who practise Sirshasana, Pranayama comes by itself. It is obvious from these examples that when the mind is deeply concentrated on any subject, the respiration slows down or stops. Pranayama is being done automatically. Mind and Prana are intimately connected. If you turn your attention to watch the breath on those occasions, it will regain its normal state. Pranayama comes by itself to those who are deeply absorbed in doing Japa, Dhyana and Brahma-Vichara (enquiry of Atman).
Prana, mind and Virya (seminal energy) are under one Sambandha (connection). If you can control the mind, Prana and Virya are controlled by themselves. If you can control Prana, mind and Virya are controlled by themselves. If you control the Virya by remaining as an Akhanda Brahmachari without emission of even a single drop of semen for 12 years, mind and Prana are controlled by themselves. Just as there is connection between wind and fire (light), so also there is connection between Prana and mind. Wind fans the fire. Prana also fans the mind. If there is no wind, fire or light gets steady. Hatha Yogins approach Brahman by controlling Prana. Raja Yogins approach Brahman by controlling mind.
In this Pranayama you need not close the nostrils. Simply close the eyes if you practise it in a sitting posture. Forget the body and concentrate. If you practise this during walking, just feel minutely the movement of the air that is inhaled and exhaled.
