Chandrabhedan 1 || Chandranadi || Chandraabhyas || Moon Energy || Ida Nadi || Insomnia || Headache

In Hatha Yoga, the left nostril is associated with our body’s cooling energies. It corresponds with Ida nadi and is symbolized by the characteristics of the Moon. By activating only your left nostril through Chandrabhedan Pranayama, we imbibe the qualities of the Moon within us. Chandrabhedan is a pranayama but here, we are only discussing the first stage of breathing i.e. without breath retention.

Technique

Hand Position

Use right hand – We always use right hand during pranayama practice.

Assume Pranav Mudra i.e. your right index and right middle fingers are folded whereas right thumb, right ring and right little fingers are kept straight.
Assume any comfortable sitting position
Your spine has to be neutral and aligned
Your mind alert and focused on your breathing
Softly block your right nostril with your right thumb just below the nasal bone
Inhale softly but deeply from the left nostril, block your left nostril with the ring finger, release the thumb lock on the right nostril and exhale from the right nostril. This is one cycle of Chandrabhedan.
Block your right nostril again with right thumb, release your lock on the left nostril by removing the right ring finger, inhale from the left nostril again, and block your left nostril with right ring finger, release right thumb from the right nostril and exhale from the right nostril. The previous detailed instruction may sound confusing. Follow the instructions word to word, practice it a few times and then it would be easy to perform.

The important critical point is to ensure that you only inhale from the left nostril and only exhale from right.
Alternate Method,

You can also choose to inhale and exhale only from the left nostril by keeping your right nostril blocked. That way only your left nostril is at work. This practice is known as “Chandraabhyas”.

There is no mention of Chandarabhedan in Hathapradipika and Gheranda Samhita. It is believed, however, that the practices and techniques not mentioned in classical texts still form a part of continuing tradition.

Duration

Start with a 30 second practice and gradually increase the duration to 2-3 minutes or more as per your comfort.
Train yourself gradually to double the ratio of exhalation to inhalation. Please ensure full inhalation and complete exhalation to avoid shallow breathing.
