Chandra Bhedana
Chandra Bhedana (चन्द्र भेदन) is a prāṇāyāma technique in which inhalation is performed exclusively through the left nostril (the moon channel) and exhalation through the right. The name means “moon-piercing,” referring to the activation of the lunar nāḍī (ida).
Overview
Chandra Bhedana is the complementary practice to Sūrya Bhedana, designed to activate the parasympathetic nervous system, cool the body, and calm the mind. It is associated with the moon (chandra) and the ida nāḍī, and is traditionally recommended for practice in the evening or during hot conditions.
Method
The practitioner sits in a meditative posture and closes the right nostril with the thumb of the right hand. Inhalation is performed slowly and deeply through the left nostril, followed by retention (kumbhaka) as prescribed. Exhalation is then performed through the right nostril after closing the left nostril with the ring finger. The practice is typically performed for 15–20 minutes.
