Nāḍī Śodhana

Nāḍī Śodhana (नाडी शोधन) is a prāṇāyāma technique involving alternate nostril breathing, designed to purify the nāḍīs (energy channels). The name means “channel purification” (nāḍī = energy channel, śodhana = purification). The Yoga Sūtras and Hatha Yoga Pradīpikā describe the fundamental importance of nāḍī purification:

नाडीशुद्धौ वातरोगनिवृत्तिः
Nāḍī-śuddhau vāta-roga-nivṛttiḥ
“When the nāḍīs are purified, diseases of the vital breath are removed.”

Nāḍī Śodhana is considered one of the most important prāṇāyāma practices, serving as a foundation for advanced breathwork and meditation.

Origins

The practice of alternate nostril breathing appears throughout yogic literature. The Yoga Sūtras (2.29) include prāṇāyāma as the fourth limb of yoga, and Nāḍī Śodhana is understood to be one of its primary techniques. The Hatha Yoga Pradīpikā (2.7–2.8) provides detailed instructions, stating:

प्राणायामं तु कर्तव्यं नाडीशोधनम् आदितः
Prāṇāyāmaṃ tu kartavyaṃ nāḍī-śodhanam āditaḥ
“Prāṇāyāma should be performed beginning with nāḍī purification.”

The Śiva Saṃhitā describes it as essential for balancing the lunar (ida) and solar (pingalā) energy channels.

Technique

The practitioner uses the right hand in viṣṇu mudrā, folding the index and middle fingers. The right thumb closes the right nostril, and the ring finger closes the left nostril. The Hatha Yoga Pradīpikā (2.8) instructs:

पूर्वं वामनासिका रन्ध्रे वायुः कार्यो विशेषतः
Pūrvaṃ vāmanāsikā randhre vāyuḥ kāryo viśeṣataḥ
“First, the breath should be drawn in through the left nostril specifically.”

The basic pattern is:

1. Close right nostril, inhale through left
2. Close both nostrils, retain breath
3. Close left nostril, exhale through right
4. Inhale through right
5. Close both nostrils, retain
6. Close right nostril, exhale through left

This completes one cycle. Traditional ratios are 1:4:2 (inhale:retain:exhale).

Benefits (as claimed by tradition)

Traditional texts claim Nāḍī Śodhana:

• Purifies and balances the iḍā and piṅgalā nāḍīs
• Balances the lunar and solar currents of prāṇa
• Calms the mind and prepares for meditation
• Removes blockages in the energy channels
• Regulates the flow of prāṇa throughout the body

The Hatha Yoga Pradīpikā states that it “destroys diseases” and “awakens kuṇḍalinī.”

In modern practice

Nāḍī Śodhana is one of the most widely taught prāṇāyāma techniques in contemporary yoga. It is valued for its calming effects and is often used as a preparatory practice before meditation. Studies have reported reductions in anxiety, lower blood pressure, improved respiratory function, and balanced autonomic nervous system activity. It is considered safe for most practitioners and is frequently included in yoga therapy protocols.
