Chandra Bhedana Pranayama- Left Nostril Breathing
As per the Vedic traditions the left nostril is associated with the Ida Nadi or nerve of the body which lies to the left side of the spine and goes to the left nostril activating the right side of the brain. This nerve is associated with the coolness effect and brings ‘rest-relax’ peace of mind.
The word ‘Chandra Bhedana’ comprises of two words- ‘Chandra’ or Moon and ‘bhedana’ or piercing. Therefore, the literal meaning of this pranayama is the ‘piercing of moon’.
The reason why this Pranayam is called chandra bheda is because this exercise calms the nerves with the cool energy which works to reduce the body heat of the body. This is opposite of Surya Bhedana pranayama in which the body heat is generated. Due to the opposite nature of the two exercises, the energies of the body remain balanced.
In the Left nostril breathing, the inhalation is done only from the left nostril while keeping the right nostril blocked and the exhalation is done only from the right nostril by keeping the left nostril blocked.
Chandra Bhedana pranayama is an effective way of bringing peace and calmness to mind as it has cooling effect throughout the body. The reduction in heat of the body is useful in controlling heartburn, acidity and other digestive issues. It is also helpful in maintaining a balanced energy flow in body.
Care shall be taken to observe all precautions before and during its practice.
