Indian yoga is not merely a physical discipline; it is a systematic science of harmonizing body, mind, and consciousness. Ancient yogic texts such as the Hatha Yoga Pradipika and Gheranda Samhita describe Pranayama as the bridge between the external practices of asana and the internal practices of dharana and dhyana.
Among all pranayama techniques, Nadi Shodhana Pranayama (also known as Anulom Vilom in its simpler form) is regarded as a foundational and purificatory practice. The term is derived from Sanskrit:
Nadi – subtle energy channels
Shodhana – purificationThus, Nadi Shodhana literally means purification of the energy pathways, enabling prana (life force) to flow freely and evenly.
Yogic Concept Behind Nadi Shodhana
According to yogic physiology, the human system contains 72,000 nadis, of which three are primary:
Ida Nadi – lunar, cooling, mental, left nostril
Pingala Nadi – solar, heating, dynamic, right nostrilSushumna Nadi – central channel of spiritual awakening
Most mental disturbances arise due to imbalance between Ida and Pingala. Nadi Shodhana restores equilibrium, preparing the practitioner for higher yogic states.
