Anulom-Vilom is a widely known Pranayama. Pranayama means expansion of Pran Shakti or vital force. There are many ways of doing pranayama but the basis of all kinds of pranayama is ‘Deep Breathing’. We breathe every moment of our lives, and yet we are hardly aware of it unless and until we are afflicted with some breathing disorder. Just close your eyes for a few minutes and concentrate your attention on your breathing – you will feel as if all the tension has vanished into thin air and you feel bliss.
When we do normal breathing, our breathing is limited to area between heart and throat only. Conversely, when we inhale deeply, our lungs become filled with air and our chest gets expanded, and when we exhale deeply our lungs and chest are contracted. How and why this happens? For this, it is essential to know the structure of our lungs.
