Pranayama Foundations

The Science of Vital Energy

Pranayama is the fourth limb of yoga, positioned between asana (physical posture) and pratyahara (sense withdrawal). It is the bridge between body and mind - working with breath to influence the subtle energy that animates both.

Understanding Prana

Prana is the vital energy that pervades all living things. The word combines pra (forth) and an (to breathe) - that which moves forth, the life force.

Prana is not merely breath, though breath is its most accessible expression. It is the energy behind breath, behind thought, behind all biological function.

The Five Pranas

Classical yoga recognizes five functional aspects of prana (pancha prana):

Prana: Governs intake - breathing, eating, perception. Located in the chest.

Apana: Governs elimination - excretion, exhalation, release. Located in the lower abdomen.

Samana: Governs assimilation and digestion. Located in the navel region.

Udana: Governs upward movement - speech, expression, growth. Located in the throat.

Vyana: Governs circulation and distribution throughout the body. Pervades the entire system.

These five maintain the body’s equilibrium. Pranayama practices influence and harmonize them.

The Nadis

Nadis are the channels through which prana flows. The classical texts describe 72,000 nadis pervading the subtle body, but three are primary:

Ida: The lunar channel, running along the left of the spine. Associated with:

Pingala: The solar channel, running along the right of the spine. Associated with:

Sushumna: The central channel, running through the spine itself. When ida and pingala are balanced, prana enters sushumna:

The Four Components

Pranayama consists of four distinct phases:

Puraka (Inhalation)

The controlled intake of breath. Puraka brings prana into the system, energizes, and expands.

Practice: Smooth, even inhalation through the nostrils, using the diaphragm. No strain, no forcing.

Antara Kumbhaka (Internal Retention)

Holding the breath after inhalation. This is where prana is absorbed and distributed. Retention is the heart of pranayama.

Practice: Hold only what is comfortable. Never strain. The hold should be steady, not desperate.

Rechaka (Exhalation)

The controlled release of breath. Rechaka releases carbon dioxide, removes stale prana, and calms the nervous system.

Practice: Typically longer than inhalation. Smooth, complete, controlled.

Bahya Kumbhaka (External Retention)

Holding the breath after exhalation. This creates a profound stillness and is considered more advanced.

Practice: Proceed with caution. External retention should only be practiced after proficiency in other phases.

Classical Ratios

Traditional pranayama prescribes specific ratios between the phases. A common progression:

Beginning: 1:0:1:0 (equal inhale:exhale, no retention)

Intermediate: 1:1:2:0 (inhale, hold same count, exhale double)

Advanced: 1:4:2:0 (inhale, hold four times, exhale double)

These ratios should develop gradually over months or years. Forcing ratios before readiness is harmful.

Foundational Techniques

Diaphragmatic Breathing

Before any technique, correct breathing must be established:

Many people breathe in reverse (chest rising, belly pulling in). This must be corrected first.

Nadi Shodhana (Alternate Nostril Breathing)

The most important pranayama for beginners. It balances ida and pingala:

  1. Close the right nostril; inhale through the left
  2. Close both nostrils; retain briefly
  3. Close the left nostril; exhale through the right
  4. Inhale through the right
  5. Retain briefly
  6. Exhale through the left
  7. This is one round

Practice 5-15 rounds. This calms the mind, balances the nervous system, and prepares for meditation.

Ujjayi (Victorious Breath)

A slightly constricted throat breath that creates an audible sound:

  1. Constrict the back of the throat slightly
  2. Breathe through the nostrils
  3. A soft sound (like distant ocean waves) occurs
  4. Maintain even length of inhale and exhale

Ujjayi heats the body, increases awareness, and focuses the mind. It can be used during asana practice.

Bhramari (Bee Breath)

A humming exhalation that calms the mind:

  1. Inhale fully
  2. On exhalation, make a steady humming sound
  3. Feel the vibration in the head
  4. Repeat 5-10 times

Bhramari reduces anxiety, prepares for meditation, and is accessible to beginners.

Cautions and Contraindications

Pranayama is powerful and can cause harm if practiced incorrectly:

Never force: Strain indicates you have exceeded your capacity. Back off.

Proceed gradually: Add retention only after months of basic practice. Extend ratios slowly.

Contraindications include:

When in doubt, practice simple diaphragmatic breathing without retention.

Seek guidance: Advanced pranayama should be learned from a qualified teacher, not from books or videos alone.

Effects and Benefits

Pranayama, properly practiced, produces:

Physical effects:

Mental effects:

Energetic effects:

Pranayama and Meditation

The purpose of pranayama is to prepare for meditation. When prana is regulated, the mind becomes still.

“tasmin sati svasa prasvasayor gati vicchedah pranayamah” (II.49) “Pranayama is the regulation of incoming and outgoing breath, established after asana.”

“dharana su cha yogyata manasah” (II.53) “And the mind becomes fit for concentration.”

The breath and mind are intimately connected. By calming one, we calm the other. This is the practical wisdom of pranayama.
