Chandra Bhedana pranayama

The basis of life is breathing, a process that links the body's physiology to the current state of the mind. — In yoga, pranayama is the practice of consciously regulating the breath in order to channel vital energy (prana) through the body's channels and synchronize the body's functions with the state of the mind¹. — This practice allows the practitioner to directly influence the autonomic nervous system, thereby balancing internal processes and creating a foundation for deep meditation². — Among the many techniques that aim to create tranquility, Chandra Bhedana pranayama, also known as "moon breathing," stands out for its cooling and soothing effect.

The name of this technique is derived fr om the Sanskrit words "chandra" (meaning 'moon') and "bhedana" (meaning 'to pierce' or 'to pass through'). Thus, the name literally translates as 'moon-piercing breath' or 'breath that passes through the lunar channel,' and its essence lies in passing through the left nostril to purposefully activate the Ida nadi — an energetic channel associated with lunar, cooling, and feminine energy as well as intuition and the parasympathetic nervous system³.

Regular practice of Chandra Bhedana pranayama is meant to help you achieve inner peace, reduce mental noise, and prepare your consciousness for deep meditation. It is especially relevant in today's stimulus-saturated world, wh ere our minds rarely get the opportunity to truly rest.

The benefits of Chandra Bhedana pranayama manifest on the physical, mental, and energetic planes, as confirmed by both the centuries-old tradition of yoga and the ever-growing number of modern scientific studies⁴.

Physiological and therapeutic benefits:

• Effective rest and relaxation. This practice gradually shifts the body into a mode of rest and recovery — the main focus of the parasympathetic nervous system. This manifests as steady slowing of the heart rate and breathing as well as deep relaxation of the muscles. Studies of brain activity (EEG) also reveal that this state is often associated with deep inner calmness⁵.
• Decreased blood pressure. This technique helps relax blood vessels and decrease levels of stress, thereby allowing blood pressure to decrease in a gentle and lasting way. This establishes Chandra Bhedana as a highly useful complementary tool in the complex approach to managing hypertension⁶.
• "Cooling" of the body. In Ayurvedic tradition, this technique is used to reduce inner heat (i.e. manage Pitta dosha), making it useful for those prone to overheating, irritability, and inflammatory processes.
• Improved sleep. Evening practice relieves accumulated daily stress, calms the stream of consciousness, and helps the body transition into a state that facilitates good sleep. More specifically, it helps one fall asleep more quickly and makes sleep deeper and more restorative.

Psycho-emotional and energetic benefits:

• Reduction of anxiety and stress. Systematic practice leads to a decrease in the levels of stress hormones (e.g. cortisol, which breaks the cycle of anxious thoughts and helps develop great emotional resilience)⁷.
• Development of intuition and creativity. Activization of the Ida nadi and the corresponding right hemisphere of the brain creates an internal space in which intuitive insights, creative ideas, and nonlinear thinking can easily emerge.
• Harmonization of the feminine principle. This practice is associated with the harmonization of the feminine aspects of energy: acceptance, fluidity, sensitivity, and inner knowledge. It is quite useful for relieving emotional tension during the premenstrual period.
• Preparation for meditation. By calming the mind and alleviating mental tension, Chandra Bhedana perfectly prepares one for their transition into a state of deep meditation and contemplation.

Despite its gentle nature, Chandra Bhedana pranayama is a powerful technique for working with energy; therefore, disregarding key contraindications may lead to imbalance and a deterioration in wellbeing. In addition, it is highly important to practice with close attention to the signals sent by your mind and body.

Absolute and relative contraindications:

• Hypotension and bradycardia. This practice may exacerbate these conditions, causing a further drop in blood pressure or a slowing of the heart rate.
• Depression or intense apathy. Chandra Bhedana may intensify feelings of lethargy and fatigue.
• Nasal congestion or acute respiratory diseases. This practice is ineffective in cases of airway obstruction.
• Pregnancy. Pregnant individuals, specifically those in their first trimester or those experiencing complications, must consult with a doctor prior to beginning practice.
• Severe exhaustion or fatigue. In such states, your priority must always be complete rest and not practice.

Key precautions:

• If you have any chronic health conditions (particularly cardiovascular, neurological, or psychiatric), please consult your physician or an experienced yoga instructor before beginning practice.
• It's recommended to start with a small number of cycles, focusing on quality rather than quantity. Gradually, over the course of many weeks and months, you'll find the right time to increase the duration of your practice sessions, so don't strive to do so immediately.
• During practice, you should not experience any tension, dizziness, or shortness of breath. Your breathing should remain smooth, silent, and controlled.
• Practice should be performed on an empty stomach and in a calm, clean, well-ventilated environment.

Stage 1. Preparation

1. Sit in a stable position with a straight spine (e.g. Sukhasana, Vajrasana, Padmasana, or in a chair). For added comfort, you may place a folded blanket under your pelvis. Close your eyes.
2. Place your left hand on your left knee, joining your thumb and pointer finger in Jnana mudra (palm facing down) or Chin mudra (palm facing up).
3. Relax your right hand and use one of the two finger positions described below to close the nostrils:
   • Option A — Vishnu mudra: bend the pointer and middle fingers and press them against the palm; at the same time, position the thumb by the right nostril and the ring finger by the left.
   • Option B — Nasikagra mudra: place the fingertips of the pointer and middle fingers on the point between the eyebrows; cover the right nostril with the thumb and the left with the ring finger.

Choose the position which will allow you to cover your nostrils comfortably and without strain.

Stage 2. Main breathing cycle.

1. Take a calm, complete exhale through both of your nostrils.
2. Gently but firmly cover your right nostril with the thumb of the right hand while keeping the left completely open.
3. Inhale slowly, smoothly, and deeply through your left nostril for 4-5 seconds.
4. Exhale slowly, smoothly, and deeply through your right nostril for 4-5 seconds.
5. Continue breathing in this manner for the necessary amount of cycles.
6. After making a final exhalation through your right nostril, release it and take 2-3 calm, balancing breaths (where one breath is an inhalation and an exhalation) through both nostrils.

Stage 3. Advanced variation (with breath retention).

Once you've mastered the basic rhythm, you may introduce an internal breath hold (antar-kumbhaka) with a sequence of inhalation, hold, exhalation.

1. Inhale through your left nostril for 4 seconds.
2. Hold your breath and softly cover both nostrils for about 2 seconds. If you want and can, tilt the chin lightly toward the chest (Jalandhara bandha).
3. Exhale through your right nostril for 6 seconds.

Start with a short breath retention (e.g. 4:2:6), increasing the duration very gradually (to 6:3:9, 8:4:12, etc.) when you feel truly comfortable, making sure to avoid tension or panic.

Stage 4. Finishing the practice.

After completing the planned number of cycles, lower your right hand onto your knee. Continue breathing naturally and calmly through both nostrils for 1-2 minutes, observing the sensations— feelings of coolness, relaxation, and mental stillness— that arise in your body. Only after this may you open your eyes.

Consistency is crucial for achieving long-lasting results: for instance, it's far better to practice for 5-10 minutes daily than for an hour once a week. The ideal time for practice is generally considered to be the late evening (to unwind just before bed) or midday (to relieve the tension accumulated in the first half of the day). Practicing in the morning is not recommended, as it may decrease the energy levels that you need.

Within the context of a yoga session, Chandra Bhedana is performed after asanas and immediately before meditation. For overall balance, it can be alternated on a daily basis with Surya Bhedana (solar breathing in the morning, lunar breathing in the evening). This practice also pairs well with gentle, restorative asanas such as those drawn from the Yin yoga tradition.

To conclude, despite all its benefits, Chandra Bhedana pranayama isn't mentioned in a single ancient text and has started gaining popularity only in the 20th century, catering primarily to a Western audience. — On the same note, it's important to note that some people have reservations about this practice, believing that it activates the less favorable aspects of one's personality and should therefore be undertaken exclusively in special conditions and under the careful guidance of an experienced instructor.

"When the breath wavers, the mind is unstable. When the breath is calm, the mind too gains peace and the yogin achieves steadiness. Therefore, one should restrain the breath."
