Nadi Shodhana — Pranayama

Nadi Shodhana, or alternate nostril breathing, is the foundational purification practice of the pranic body, designed to cleanse and balance the two principal energy channels, Ida and Pingala, which flow along either side of the central Sushumna nadi. Ida governs the lunar, cooling, and mentally receptive qualities associated with the left side of the body, while Pingala governs the solar, heating, and active qualities of the right side. When these channels are congested by stress, poor diet, or erratic breathing habits, the mind becomes agitated and prana cannot rise freely through Sushumna. By consciously directing breath through alternating nostrils using the fingers of the right hand in Vishnu Mudra, the practitioner gradually dissolves these blockages, harmonizing the sympathetic and parasympathetic nervous systems. Classical texts such as the Hatha Yoga Pradipika prescribe Nadi Shodhana as a preparatory practice before deeper kumbhaka work, since a purified nadi system is required before retention can be safely extended. Regular practice produces a subtle sense of equanimity, sharpens concentration, and prepares the subtle body for the awakening of Kundalini by ensuring that prana moves evenly rather than erratically. It is considered safe for nearly all levels and is often the first pranayama taught to new students.

Sit in a comfortable meditative posture with the spine erect. Form Vishnu Mudra with the right hand, folding the index and middle fingers. Close the right nostril with the thumb and inhale slowly through the left nostril for a count of four. Close the left nostril with the ring finger, release the thumb, and exhale through the right nostril for a count of four. Inhale through the right nostril, then switch and exhale through the left. This completes one round. Continue for 8-12 rounds, keeping the breath smooth, silent, and free of strain.

Balances the left and right hemispheres of the brain, calms the nervous system, reduces anxiety and mental fatigue, improves respiratory efficiency, and prepares the mind for meditation. It also purifies the subtle nadis, allowing prana to flow more evenly through the body and supporting hormonal balance.

Avoid during severe nasal congestion, cold, or sinus infection, as forced breathing through blocked nostrils can create strain. Those with severe hypertension or heart conditions should practice without breath retention and under supervision.
