Pranayama During Meditation
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.
