12.1 Preparatory Breathing Practices & Syllabus Pranayamas (Practical 6 & 7)

Key Takeaways

  • As commonly taught (for example, in the S-VYASA tradition), Sectional Breathing (Vibhagiya Pranayama) trains the three anatomical lung compartments: Abdominal/Diaphragmatic (Adhama, ~60% capacity) paired with Chin Mudra, Thoracic/Intercostal (Madhyama, ~30% capacity) paired with Chinmaya Mudra, and Clavicular/Apical (Adhyama, ~10% capacity) paired with Adhi Mudra.

  • Full Yogic Deep Breathing integrates the three sectional chambers into a continuous, smooth, three-dimensional wave (inhalation: abdomen expands -> chest expands -> collarbones lift; exhalation: collarbones drop -> chest contracts -> abdomen gently draws in) practiced with Brahma Mudra.

  • The YWI syllabus marks Ujjayi, Sheetali, Sitkari and Bhramari '(Without Kumbhaka)'; Anuloma Viloma is a preparatory practice with no retention specified, and teaching it without retention is the safe default for wellness groups.

  • Nadi Shodhana is demonstrated using Nasika / Vishnu Mudra on the right hand and Chin / Jnana Mudra on the left, following the exact single-round sequence: Inhale Left (Ida) -> Exhale Right (Pingala) -> Inhale Right -> Exhale Left, always initiating and concluding through the left nostril.

  • The syllabus cooling practices (Sheetali and Sitkari) inhale orally and exhale nasally to reduce body temperature and soothe Pitta, whereas Bhramari induces a 15-fold surge in paranasal nitric oxide and stimulates vagal tone via resonant humming nasal exhalation with tragus or Shanmukhi Mudra closure.

Preparatory Breathing Practices & Syllabus Pranayamas (Practical 6 & 7)

Quick Answer: Practical Syllabus 6 & 7 evaluates foundational respiratory mechanics and classical breath regulation. Candidates must demonstrate Sectional Breathing (Vibhagiya Pranayama) across its three anatomical compartments—Abdominal (Adhama, ~60% capacity) with Chin Mudra, Thoracic (Madhyama, ~30% capacity) with Chinmaya Mudra, and Clavicular (Adhyama, ~10% capacity) with Adhi Mudra—before synthesizing them into seamless Full Yogic Breathing using Brahma Mudra. The syllabus marks Ujjayi, Sheetali, Sitkari and Bhramari "(Without Kumbhaka)"; Anuloma Viloma / Nadi Shodhana is listed among the preparatory breathing practices, and teaching it without retention at this level is the safe default.


The Physiology of Yogic Breathing: From Autonomic Reflex to Conscious Prana

In routine human physiology, respiration is primarily an involuntary autonomic activity coordinated by the respiratory rhythmicity center in the medulla oblongata and the pontine respiratory group (pneumotaxic and apneustic centers) in the pons. Under sedentary conditions, shallow thoracic breathing dominates, ventilating primarily the upper anatomical dead space and leaving the rich capillary beds in the lung bases poorly perfused.

In Yogic science, respiration is the physical manifestation of Prana—the vital life force that links the physical body (Annamaya Kosha) to the subtle mind (Manomaya Kosha). As sage Svatmarama declares in the Hatha Yoga Pradipika (HYP 2.2):

"Chale vate chalam chittam nishchale nishchalam bhavet, yogi sthanutvam apnoti tato vayum nirodhayet."
"When breath is unsteady, the mind is unsteady; when breath is still, the mind is still. The Yogi attains steadfastness; therefore, one should restrain the breath."

Before embarking on classical Pranayama, the practitioner must develop conscious neuro-respiratory control through preparatory sectional breathing, training the three anatomical chambers of the respiratory apparatus.


1. Sectional Breathing (Vibhagiya Pranayama — Practical 6.1)

Sectional breathing isolates and restores normal functional excursion to the three distinct anatomical zones of the lungs. For examination demonstration, each practice is performed in a steady meditative posture (Padmasana, Siddhasana, Swastikasana, or Vajrasana) with the spine, neck, and head vertically aligned.

1.1 Abdominal or Diaphragmatic Breathing (Adhama Pranayama)

  • Anatomical Mechanics: The diaphragm—the primary dome-shaped muscle of inspiration—contracts and flattens downward toward the abdominal cavity. This increases the vertical dimension of the thoracic cavity, creating negative intrathoracic pressure that draws air deep into the inferior lobes of the lungs. As the diaphragm descends, it exerts gentle downward pressure on the abdominal viscera, causing the anterior abdominal wall to expand outward smoothly during inhalation. On exhalation, the diaphragm relaxes and ascends to its resting dome shape, and the abdominal wall gently recoils inward.
  • Lung Capacity Utilization: Accounts for approximately 60% of total lung ventilation. The lung bases possess the highest concentration of alveoli and the highest ratio of capillary perfusion.
  • Mudra commonly used: Chin Mudra (the tips of the thumb and index finger touch to form a gentle circle, while the other three fingers are extended straight and relaxed; hands rest on the knees with palms facing upward).
  • Physiological Action: Rhythmic diaphragmatic excursion stimulates the afferent fibers of the vagus nerve (Cranial Nerve X) traversing the esophageal hiatus, shifting autonomic balance from sympathetic overdrive to parasympathetic dominance (rest and digest). It lowers resting heart rate, reduces salivary cortisol, and enhances venous return to the right atrium via the respiratory pump.
  • Teaching Cues & Demonstration: Instruct students to place their right hand lightly on the navel and left hand on the chest. During inhalation, only the right hand should rise outward; the chest must remain stationary. Avoid forceful pushing or abdominal cramping.

1.2 Thoracic or Intercostal Breathing (Madhyama Pranayama)

  • Anatomical Mechanics: With the abdominal wall kept relatively stable and engaged, inhalation is driven by the contraction of the external intercostal muscles. These muscles lift the ribs upward and outward in a "bucket-handle" and "pump-handle" motion, expanding the transverse and anteroposterior diameters of the mid-thorax. Air fills the middle lobes (and lingular segments) of the lungs. During exhalation, the external intercostals relax, the internal intercostals gently assist, and the ribcage compresses inward and downward.
  • Lung Capacity Utilization: Accounts for approximately 30% of total lung ventilation.
  • Mudra commonly used: Chinmaya Mudra (the tips of the thumb and index finger touch to form a circle, while the remaining three fingers are curled inward so their tips rest against the palm; hands rest on knees with palms facing upward).
  • Physiological Action: Enhances ribcage mobility, relieves intercostal muscle rigidity, stretches the parietal and visceral pleura, and improves oxygen saturation during moderate physical exertion.
  • Teaching Cues & Demonstration: Place both palms against the lateral sides of the lower ribcage. Inhale while actively expanding the ribs sideways into the palms, keeping the abdomen motionless. Exhale and feel the ribs retract.

1.3 Clavicular or Apical Breathing (Adhyama Pranayama)

  • Anatomical Mechanics: With both the abdomen and lower ribcage stabilized, inhalation is mediated by the accessory muscles of respiration—primarily the sternocleidomastoid, scalene muscles, and pectoralis minor. These muscles pull the upper ribs, sternum, and clavicles (collarbones) upward, drawing air into the narrow apical segments of the lungs. Exhalation occurs through passive elastic recoil of the upper chest tissues.
  • Lung Capacity Utilization: Accounts for approximately 10% of total lung ventilation.
  • Mudra commonly used: Adhi Mudra (the thumb is folded across the palm toward the base of the little finger, and the four fingers fold over the thumb to form a light fist; fists rest on the upper thighs with knuckles facing upward).
  • Physiological Action: Re-aerates the pulmonary apices, which are prone to stagnation, atelectasis, and microbial vulnerability in sedentary shallow breathers.
  • Teaching Cues & Demonstration: Place fingertips lightly on the collarbones. Inhale gently without arching the lower back or tensing the neck; observe the subtle rise of the clavicles. Exhale and feel them settle. Candidates must avoid hunching the shoulders toward the ears.

2. Full Yogic Deep Breathing (Practical 6.2)

Full Yogic Deep Breathing (Dirgha Pranayama / Purna Yogic Shvasana) harmonizes the three isolated sectional movements into one continuous, fluid, three-dimensional respiratory wave.

Sequence and Wave Dynamics

  • Inhalation Wave (Puraka):
    1. Air enters smoothly through both nostrils.
    2. The breath begins in the lower abdomen as the diaphragm descends and the belly gently expands outward (Abdominal / Adhama phase).
    3. Without pause, the expansion ripens into the mid-chest as the ribcage spreads laterally and anteriorly (Thoracic / Madhyama phase).
    4. The expansion finishes as the upper chest and collarbones subtly lift (Clavicular / Adhyama phase).
    5. The entire inhalation forms an unbroken, harmonious crescendo like water filling a tall vase from bottom to brim.
  • Exhalation Wave (Rechaka):
    1. Exhalation proceeds smoothly in the exact reverse sequence: the collarbones gently descend first.
    2. The ribcage deflates and retracts inward and downward.
    3. Finally, the lower abdomen gently draws inward toward the spine, expelling the residual functional volume.
  • Mudra commonly used: Brahma Mudra (both hands formed into Adhi Mudra fists, placed together at the navel center or lower abdomen with knuckles touching and thumbs directed toward the abdomen; alternatively, hands resting in Chin Mudra on the knees).
  • Examiner Pitfalls: Avoid jerky or step-wise transitions; the movement must be a single uninterrupted wave. Avoid paradoxical breathing (sucking the abdomen in during inhalation) and excessive muscular strain.

3. Classical Concept of Puraka, Rechaka & Kumbhaka (Practical 7.1)

Classical Pranayama consists of three essential phases:

  1. Puraka (Controlled Inhalation): The intentional, measured intake of atmospheric air through the nostrils.
  2. Rechaka (Controlled Exhalation): The slow, prolonged, uniform expulsion of breath. In yogic physiology, Rechaka should naturally become twice the duration of Puraka (1:2 ratio) as mastery develops.
  3. Kumbhaka (Breath Retention): Derived from Kumbha (a water pot or pitcher). The state in which the respiratory movement is suspended, making the torso still and contained like a full vessel.

Classical Classification of Kumbhaka

  • Abhyantara / Antar Kumbhaka: Internal retention—holding the breath inside after a full Puraka.
  • Bahya / Bahir Kumbhaka: External retention—holding the breath outside after a complete Rechaka.
  • Sahita Kumbhaka: Intentional retention practiced together with (Sahita) deliberate inhalation and exhalation (e.g., Suryabhedana, Ujjayi, Sheetali, Bhastrika).
  • Kevala Kumbhaka: Spontaneous, effortless cessation of respiration occurring independently of Puraka or Rechaka when mental fluctuations cease (Patanjala Yoga Sutra 2.51: "Bahyabhyantara-vishayakshepi chaturthah"; Hatha Yoga Pradipika 2.71–73).

Important

YCB Level 2 Wellness Rationale: Why "Without Kumbhaka"?
The syllabus marks items 7.2–7.5 (Ujjayi, Sheetali, Sitkari, Bhramari) "(Without Kumbhaka)". It gives no reason, but the likely rationale is safety: breath retention can raise intrathoracic, intracranial, and intraocular pressure, posing severe risks for individuals with undiagnosed hypertension, glaucoma, cerebrovascular fragility, or ischemic heart disease. A certified Level 2 Yoga Wellness Instructor operates in community and workplace settings where participants possess diverse, non-screened health profiles; hence, prioritizing smooth, continuous Puraka-Rechaka cycles delivers optimal parasympathetic and pranic benefits with less cardiovascular strain.


4. Syllabus Pranayamas: Technique, Physiology & Safety (Practical 7)

4.1 Nadi Shodhana / Anuloma Viloma (Practical 6.3 & 7.1)

  • Textual Authority: Hatha Yoga Pradipika 2.7–2.10; Gheranda Samhita 5.38–45. Purification of the 72,000 Nadis is the prerequisite for all higher Hatha practices.
  • Hand Mudras:
    • Right Hand: Nasika Mudra (also termed Vishnu Mudra) — index and middle fingers are folded comfortably against the thenar eminence (palm); the thumb operates the right nostril, and the ring and little fingers operate the left nostril.
    • Left Hand: Jnana Mudra or Chin Mudra resting on the left knee.
  • Exact Single Round Cycle:
    1. Close the right nostril with the thumb; inhale slowly, silently, and deeply through the left nostril (Ida Nadi).
    2. Close the left nostril with the ring/little fingers, release the thumb, and exhale smoothly through the right nostril (Pingala Nadi).
    3. Inhale smoothly through the right nostril (Pingala Nadi).
    4. Close the right nostril with the thumb, release the left nostril, and exhale smoothly through the left nostril (Ida Nadi).
    • This completes exactly ONE round. The sequence must always begin by inhaling through the left and end by exhaling through the left.
  • Ratio at Level 2: Begin with equal 1:1 ratio (e.g., 4 seconds Puraka : 4 seconds Rechaka), gradually advancing to 1:2 (e.g., 4 seconds Puraka : 8 seconds Rechaka) without any breath holding.
  • Physiological Mechanisms: Alternating nostril airflow correlates with the ultradian nasal cycle governed by the autonomic nervous system. Left nostril breathing stimulates the contralateral right cerebral hemisphere and triggers parasympathetic activation; right nostril breathing stimulates the left hemisphere and sympathetic tone. Rhythmic alternate breathing balances hemispheric EEG power, optimizes autonomic tone, and lowers arterial blood pressure.

4.2 Ujjayi Pranayama (Practical 7.2)

  • Textual Authority: Hatha Yoga Pradipika 2.51–53 ("Mukham samyamya nadibhyamakrishya pavanam shanaih..."); Gheranda Samhita 5.68–72.
  • Technique: Seated comfortably with an erect spine. Inhale slowly and smoothly through both nostrils while partially contracting the glottis (the vocal cords / laryngeal aperture). The air passing through the narrowed glottis produces a gentle, continuous, unforced friction sound (frequently compared to distant sea waves, rustling leaves, or the soft breathing of a sleeping infant). Exhale slowly and smoothly through both nostrils while maintaining the identical soft glottic friction.
  • Physiological Mechanisms: The laminar resistance across the partially closed glottis increases intrathoracic vagal afferent firing. The slow rhythm and mild resistance are commonly explained as engaging vagal and baroreceptor reflexes, producing a drop in sympathetic output, lowering systemic vascular resistance, and stabilizing heart rate variability (HRV). It also mildly warms the inspired air and increases pulmonary gaseous diffusion.
  • Contraindications & Notes: Avoid excessive tension in the throat muscles, grimacing, or producing an abrasive rasping sound. Those with severe hypotension should practice gently without prolonged exhalation.

4.3 Sheetali Pranayama (Practical 7.3)

  • Textual Authority: Hatha Yoga Pradipika 2.57–58 ("Jihvaya vayumakrishya purvavad kumbhakam charet, shanaih ghranena rechayed..."); Gheranda Samhita 5.73–74.
  • Technique: Extend the tongue comfortably outside the mouth between parted lips. Curl the lateral edges of the tongue upward and inward to form a narrow cylindrical tube or flute (Kaki Mudra shape). Inhale deeply, smoothly, and audibly through this tongue tube; the incoming air is cooled as moisture evaporates from the lingual mucosa. At the end of inhalation, retract the tongue, close the mouth, and exhale slowly, smoothly, and completely through both nostrils.
  • Physiological & Energetic Benefits: Evaporative cooling at the tongue surface immediately reduces thermal sensation, soothes hyperacidity, quenches thirst, alleviates hunger, reduces systemic inflammation, and pacifies vitiated Pitta Dosha. It lowers body temperature and systolic blood pressure.
  • Contraindications: Severe hypotension (low blood pressure), chronic asthma, bronchitis, excessive respiratory secretions (vitiated Kapha), and exposure to freezing or heavily polluted environmental air.

4.4 Sitkari Pranayama (Practical 7.4)

  • Textual Authority: Hatha Yoga Pradipika 2.54–56 ("Sithkuryat vadane shreshtha ghranenaiva rechayet..."); Gheranda Samhita 5.75–76.
  • Technique: A separate classical practice (HYP 2.54–56) that is also a convenient alternative for people who cannot roll the tongue. Lightly press the upper and lower teeth (incisors and canines) together while parting the lips wide. Fold the tongue flat against the palate or keep the tip gently touching the lower gums. Inhale slowly and deeply through the spaces between the teeth, producing a distinct hissing sound (seeee). Retract the lips, close the mouth, and exhale smoothly and completely through both nostrils.
  • Benefits: Identical cooling and Pitta-pacifying effects to Sheetali. Additionally stimulates salivation, maintains dental and gingival micro-circulation, and alleviates psychological agitation and anger.
  • Contraindications: Same as Sheetali (hypotension, asthma, cold weather), plus sensitive teeth, severe dental caries, or active gingivitis.

4.5 Bhramari Pranayama (Practical 7.5)

  • Textual Authority: Hatha Yoga Pradipika 2.68 ("Vegad ghosham purakam bhrnganadam bhringanadam rechakam mandamandam...").
  • Technique: Sit in a steady posture with spine erect. Inhale deeply and smoothly through both nostrils. On exhalation, produce a smooth, soft, continuous humming sound resembling the buzzing of a female black bee (Bhramari—a resonant Makara / "mmmm" sound) until the lungs are empty.
  • Hand Positions Evaluated:
    1. Basic Practice: Index fingers placed on the tragus of each ear, pressing gently inward to occlude the external auditory canal.
    2. Advanced Practice: Shanmukhi Mudra (closing the six perceptual gates): thumbs on tragi, index fingers resting gently over closed eyelids, middle fingers partially occluding nostrils, ring fingers above upper lip, little fingers below lower lip.
  • Biochemical & Neurological Mechanisms:
    • Nitric Oxide (NO) Surge: Acoustic humming vibrations within the nasopharynx cause a 15-fold increase in endogenous nitric oxide production by the paranasal sinus epithelium. Nitric oxide is a potent endogenous vasodilator, bronchodilator, and broad-spectrum antiviral/antimicrobial agent.
    • Vagal Tone & Neuroplasticity: The skull-vibrating resonance stimulates the auricular branch of the vagus nerve (Arnold's nerve), inducing immediate parasympathetic dominance, marked reduction in state anxiety, and dominant bilateral alpha brainwave (8–12 Hz) activity across frontoparietal EEG leads.
  • Contraindications: Active middle ear infections (otitis media), severe mastoiditis, or purulent sinusitis.
