Chandra Bhedana Pranayama (Left Nostril Breathing) – Guide

Chandra Bhedana Pranayama (चन्द्रभेदन प्राणायाम), or Left Nostril Breathing, is a cooling, calming, and introspective yogic breath practice. It activates the Ida Nadi, associated with the moon (Chandra), which governs mental calmness, emotional balance, and cooling energy. This technique is ideal for relaxing the nervous system, reducing heat or agitation, and preparing the mind for meditation and sleep.

🔹 Reference: Hatha Yoga Pradipika (Chapter 2, Verse 50) refers to lunar breath control (Ida Nadi activation) as effective in cooling the system and pacifying mental disturbances.

Meaning & Etymology

Sanskrit Name: चन्द्रभेदन प्राणायाम (Candra Bhedana Prāṇāyāma)
Meaning:
- Chandra = Moon
- Bhedana = Piercing or Activating
- Pranayama = Breath Control
Literally, it means “piercing the moon channel” – promoting cool, tranquil energy and nervous balance through left nostril inhalation.

How to Practice Chandra Bhedana Pranayama (Piercing the Lunar Channel)

Chandra Bhedana Pranayama is a classical cooling breathing technique in which inhalation is performed exclusively through the left nostril (Ida Nadi) and exhalation through the right nostril (Pingala Nadi). The word Chandra means “moon,” symbolizing coolness, calmness, nourishment, and emotional stability. This pranayama is traditionally prescribed to pacify heat, calm the nervous system, reduce mental agitation, and promote restorative balance.

Preparatory Guidelines Before Practice

Practice on an empty stomach or at least 3–4 hours after meals.
Choose a quiet, cool, and well-ventilated environment.
Avoid practicing when the body feels excessively cold or sluggish.
Beginners should avoid breath retention in the initial stages.

Step-by-Step Method of Practice

1. Sit in a Comfortable Meditation Posture

Sit in one of the following stable postures:
- Sukhasana
- Padmasana
- Vajrasana
Keep the spine upright, chest relaxed, shoulders soft.
Align head, neck, and trunk in one straight line.
Rest the left hand on the knee in Chin or Jnana Mudra.
Gently close the eyes.

Why this is important:

A steady, upright posture allows smooth pranic flow and prevents strain in breathing.

2. Form Vishnu Mudra with the Right Hand

Fold the index and middle fingers of the right hand toward the palm.
Use:
- Thumb to control the right nostril
- Ring finger (and little finger if comfortable) to control the left nostril

Purpose of the mudra:

Facilitates precise nostril regulation and encourages focused breath awareness.

3. Close the Right Nostril

Gently press the right nostril with the thumb.
Ensure the pressure is light and comfortable.

Energetic awareness:

Closing the right nostril minimizes Pingala activity and prepares the system for lunar cooling.

4. Inhale Slowly Through the Left Nostril

Inhale smoothly and silently through the left nostril only.
Let the inhalation be slow, deep, and unforced.
Allow the breath to expand:
- lower abdomen
- rib cage
- upper chest

Inner focus:

Sense coolness, calmness, and soothing energy entering the body.

5. Close the Left Nostril & Exhale Through the Right Nostril

After inhalation, close the left nostril gently using the ring finger.
Release the thumb from the right nostril.
Exhale slowly, fully, and comfortably through the right nostril.

Breath quality:

The exhalation should be longer, softer, and smoother than inhalation.

Awareness cue:

Feel excess heat, tension, and agitation leaving the system.

6. Complete One Round and Pause Briefly

After the exhalation, pause naturally for a moment.
Observe sensations of coolness, relaxation, and mental quiet.

7. Repeat for 5–10 Rounds

Beginners: 5 rounds
Intermediate practitioners: 7–10 rounds
Advanced practitioners may gradually increase rounds under guidance.

Suggested breath ratio (advanced only):

Inhalation : Exhalation = 1 : 2

Breathing Rhythm & Mental Focus

Breath remains slow and rhythmic
No jerky or forced movements
Face, jaw, and shoulders remain relaxed
Mind stays gently attentive to the breath flow

Best Time to Practice

Evening or late afternoon
During hot weather or after intense physical activity
When experiencing emotional agitation, irritability, or mental restlessness

Sensations Commonly Experienced

Cooling sensation in nasal passages and chest
Slower heart rate
Reduced mental chatter
Emotional soothing and grounding

These indicate proper activation of Ida Nadi.

Common Practice Errors to Avoid

Breathing too forcefully
Practicing in cold or damp conditions
Practicing during severe congestion or cold
Performing immediately after meals

After-Practice Integration

Sit quietly for 1–2 minutes after completing the rounds.
Observe the calm, balanced state of body and mind.
The practice may be followed by meditation or silent sitting.

Yogic & Energetic Understanding

Chandra Bhedana activates Ida Nadi, associated with:
- cooling
- relaxation
- emotional balance
- mental clarity
Helps pacify excess pitta and nervous agitation.
Encourages downward grounding of prana and inward awareness.
Supports pratyahara and preparation for meditation.

Practice Tip

📌 Chandra Bhedana is distinct from Anulom Vilom. In this practice, inhalation is strictly through the left nostril and exhalation strictly through the right, creating a unidirectional lunar-to-solar flow. Maintain precision and gentleness for best results.

Chandra Bhedana Pranayama is a subtle yet powerful method for cultivating calmness, emotional balance, and inner cooling. By consciously guiding the breath through the lunar channel, the practitioner pacifies heat, steadies the mind, and restores harmony to the nervous system. Practiced with patience and awareness, Chandra Bhedana becomes a valuable tool for stress management, emotional regulation, and meditative readiness.

Precautions & Contraindications for Chandra Bhedana Pranayama

Chandra Bhedana Pranayama is a cooling, calming breathing technique in which inhalation is performed through the left nostril (Ida Nadi) and exhalation through the right. It strongly activates the parasympathetic nervous system, reduces internal heat, and promotes mental tranquility. While generally gentle and soothing, its sedative and cooling effects make it unsuitable for certain conditions or times if practiced without awareness.

1. Major Contraindications

Avoid or carefully modify Chandra Bhedana if you have the following conditions:

1.1. Asthma or Severe Bronchial Disorders

Deep inhalation through one nostril may:
- increase airway resistance
- trigger bronchial spasm in sensitive individuals
Excessive cooling effect may aggravate respiratory constriction.

Recommendation:

Asthma patients should avoid Chandra Bhedana unless prescribed and supervised by a qualified yoga therapist. Gentle bilateral breathing may be safer.

1.2. Low Blood Pressure (Hypotension)

Chandra Bhedana enhances parasympathetic dominance.
Can further reduce blood pressure, leading to:

- fainting

Guidance:

Individuals with low BP should practice for very short durations or avoid altogether.

The deeply calming nature may increase:
- mental dullness
- lethargy
- withdrawal symptoms
Particularly unsuitable during depressive episodes dominated by low energy.

Recommendation:

Practice only under guidance and combine with mild energizing practices if needed.

2. Conditions Requiring Caution or Modification

2.1. Chronic Sinus Congestion or Nasal Blockage

Left nostril breathing may feel restricted.
Forced inhalation can cause discomfort.

Modification:

Ensure nasal passages are clear; practice gently or postpone.

2.2. Excessive Cold Sensitivity

Cooling pranayama may aggravate cold intolerance.
Can reduce body temperature beyond comfort.

Guidance:

Limit duration and avoid practice in cold environments or winter mornings.

2.3. Sleep Disorders with Excessive Sleepiness

The advanced variations of Chandra Bhedana Pranayama—incorporating kumbhaka, silent mantra chanting, and cooling pranayamas—significantly deepen its physiological, neurological, and spiritual effects. These practices calm the nervous system, balance emotional states, reduce excess heat, and refine pranic flow through the Ida Nadi. When practiced progressively and with sensitivity, advanced Chandra Bhedana becomes a powerful tool for mental tranquility, emotional balance, and meditative readiness, offering a cooling counterbalance to the intensity of modern life.
