Anulom Vilom is the basic alternate nostril breathing — inhale one side, exhale the other, with no retention. Nadi Shodhana is the complete classical practice that includes breath retention (Kumbhaka). All Nadi Shodhana is Anulom Vilom, but not all Anulom Vilom is Nadi Shodhana.
The Simple Answer
This question causes genuine confusion because different teachers use these terms differently. Here is the classical distinction:
| Aspect | Anulom Vilom | Nadi Shodhana |
|---|---|---|
| Meaning | Alternate nostril breathing | Purification of channels (nadis) |
| Retention | No retention | Includes Kumbhaka (retention) |
| Ratio | 1:0:1 or 1:0:2 | 1:4:2 (classical Hatha prescription) |
| Level | Beginner | Intermediate to advanced |
| Purpose | Preliminary practice / daily calming | Deep nadi purification and transformation |
| Bandhas | Not required | Jalandhara + Mula Bandha during retention |
| Duration | 10–15 minutes | 15–30 minutes |
Why the Confusion Exists
In popular yoga culture — particularly on YouTube and in gym-based yoga — "Anulom Vilom" has become the common name for any alternate nostril breathing, even when retention is included. This is technically imprecise but now widely accepted in casual usage.
In classical texts like the Hatha Yoga Pradipika and Gheranda Samhita, Nadi Shodhana specifically refers to the complete practice with retention. The distinction matters for practitioners because retention changes the physiological and energetic effect significantly.
My teaching clarification: I teach Anulom Vilom as the entry-level practice: alternate nostrils, no retention, focus on smooth breath. Nadi Shodhana is introduced after 3–4 weeks when the student is comfortable with the nostril alternation and ready to add controlled retention.
Which One Should You Practice?
If you are a beginner: Anulom Vilom — simple alternation, 4:0:4 or 4:0:8, no retention. 10 rounds daily.
If you have 1+ month of daily practice: Begin adding 4-count retention after inhale. This is where Anulom Vilom becomes Nadi Shodhana.
If you have 3+ months: Work toward the classical 4:16:8 ratio progressively. This is where the deepest transformation occurs.
The Energetic Significance of Retention
In yogic physiology, the retention (Kumbhaka) is not merely a pause — it is the moment of nadi purification. The classical texts say the 72,000 nadis are purified only when retention is added. Without Kumbhaka, Anulom Vilom calms and balances; with Kumbhaka, Nadi Shodhana transforms.
