The 8 Limbs of Yoga Explained: Where Pranayama Fits

By Breathwork Studios · Updated March 2026 · 10 min read

The word "yoga" in the West has become almost synonymous with physical postures — stretching, strength, flexibility on a mat. But in its classical definition, yoga is a complete philosophical and practical system aimed at a very different goal: the stilling of the mind. The postures most people associate with yoga are just one step — the third — in an eight-step path described by the sage Patanjali approximately 2,000 years ago.

Understanding the eight limbs contextualises everything about pranayama practice: why it is done the way it is, why it precedes meditation, and what a complete practice actually encompasses.

Patanjali and the Yoga Sutras

The primary source for the eight-limb system is the Yoga Sutras of Patanjali — 196 terse aphorisms compiled around 400 CE, though drawing on traditions considerably older. Patanjali defines yoga in the second sutra: yogas chitta vritti nirodha — yoga is the cessation of the fluctuations (vrittis) of the mind (chitta). This is not a physical definition. The entire system exists to produce and sustain this state of mental stillness.

The eight limbs — Ashtanga, from Sanskrit ashta (eight) + anga (limb) — are described in the second chapter (Sadhana Pada) as the practical means of achieving this state. They are sequential: each prepares the ground for the one that follows.

The Eight Limbs

1. Yama — Ethical Restraints

The first limb consists of five ethical principles governing how one relates to the world:

• Ahimsa — non-violence, non-harming (in thought, word, and action)
• Satya — truthfulness, honesty
• Asteya — non-stealing (including theft of time, energy, and credit)
• Brahmacharya — continence, appropriate use of vital energy
• Aparigraha — non-possessiveness, non-greed

The Yamas are the outermost layer of the system — the ethical foundation without which the deeper practices cannot take root. A mind engaged in harmful, dishonest, or grasping behaviour cannot achieve the stillness yoga aims for. This is not moralising — it is practical: ethical turbulence creates mental turbulence.

2. Niyama — Personal Observances

Five practices governing one's relationship with oneself:

• Saucha — cleanliness, purity (of body, environment, and mind)
• Santosha — contentment, acceptance of what is
• Tapas — discipline, the "burning" purification of consistent practice
• Svadhyaya — self-study, including study of sacred texts
• Ishvara Pranidhana — surrender to a higher principle or the divine

The Niyamas work on the internal environment. Together with the Yamas, they create the ethical and psychological conditions in which the physical and energetic practices become effective rather than merely gymnastic.

3. Asana — Physical Posture

Patanjali devotes just three sutras to asana — far less than the extensive treatment it receives in modern yoga. His definition is elegant: sthira sukham asanam — posture that is steady (sthira) and comfortable (sukham). The purpose of asana in the classical framework is not fitness or flexibility but the preparation of the body for sitting still long enough for pranayama and meditation to work.

The 84 classical postures described in Hatha Yoga texts — and the thousands of variations taught in modern studios — all serve this foundational purpose: a body that is neither restless with tension nor collapsed in fatigue can hold the stillness meditation requires.

4. Pranayama — Breath Regulation

The fourth limb, and the primary focus of Yogi Breath. Patanjali defines pranayama as the regulation of the incoming and outgoing breath flow — the conscious control of inhalation, exhalation, and retention.

Its position in the sequence is significant: it comes after the body has been prepared by asana and before the internal withdrawal of the senses. Pranayama is the bridge between the outer (physical) practices and the inner (mental) practices. It works on the pranamaya kosha — the energy body — which mediates between the physical body and the mind.

Patanjali describes pranayama as removing the covering that obscures inner light — a metaphor for the mental clarity and perceptual opening that sustained practice produces. He identifies four aspects: external retention, internal retention, the movement of the breath, and the precision of place, time, and count.

5. Pratyahara — Withdrawal of the Senses

The fifth limb marks the transition from the outer to the inner practices. Pratyahara is the deliberate withdrawal of the senses from their objects — a turning of awareness inward so that sounds, sights, and sensations lose their power to distract.

Pranayama directly prepares pratyahara: the settled, inward-focused state produced by sustained pranayama is already a partial pratyahara. The complete sensory withdrawal of techniques like Bhramari with Shanmukhi Mudra (closed ears and eyes) is explicitly a pratyahara practice embedded within pranayama.

6. Dharana — Concentration

The first of the three inner limbs (Samyama). Dharana is the binding of awareness to a single object — a mantra, a point in the body, a visualisation, or the breath. The mind is gathered and directed rather than scattered across multiple objects.

This is what most people experience as the beginning of meditation: the deliberate attempt to hold attention on one thing. The difficulty of dharana — the constant drift of attention — is what pranayama's earlier attention training helps address.

7. Dhyana — Meditation

When the binding of dharana becomes continuous — when attention flows uninterruptedly toward the object without effort or interruption — it becomes dhyana. This is not an act of concentration but a state: the effortless flow of awareness. The classic analogy is oil poured from a spoon — continuous, smooth, unbroken.

The difference between dharana and dhyana is not of kind but of quality: dharana is concentrated effort, dhyana is effortless continuity. Most people experience momentary dhyana within dharana practice — brief periods where the effort falls away and pure awareness remains.

8. Samadhi — Integration / Absorption

The eighth limb and the goal of the entire system. Samadhi is the state in which the boundary between the meditator, the act of meditation, and the object of meditation dissolves. Subject-object duality temporarily resolves into pure awareness.

Patanjali describes multiple levels of samadhi, from states with form and thought to the highest formless absorption (nirbija samadhi) in which even the subtlest mental modifications cease. This is yoga in its original meaning — union.

How the Limbs Work Together

The eight limbs are not eight separate practices to be taken up and put down independently. They form a single integrated path where each prepares the ground for the next:

• Yama and Niyama create the ethical and psychological stability that makes the physical practices meaningful
• Asana prepares the body for the stillness pranayama requires
• Pranayama purifies and regulates the energy body, creating the conditions for sensory withdrawal
• Pratyahara withdraws the senses, enabling the sustained inner focus of dharana
• Dharana concentrated and refined becomes dhyana
• Dhyana deepened becomes samadhi

In practice, most modern practitioners work primarily with limbs 3 and 4 (asana and pranayama) and begin exploring 5–7 (pratyahara, dharana, dhyana) through meditation. This is a complete and deeply worthwhile practice, even without engaging the full system.

The Place of Pranayama in Modern Practice

The Yogi Breath app's six-level curriculum — Newbie through Yogi — follows the classical pranayama progression embedded within this eight-limb framework. It does not require engagement with the full system, but for practitioners who want to understand why pranayama is structured as it is, the eight-limb context provides the answer: pranayama is not a breathing exercise. It is the fourth step in a 2,000-year-old map of human development.
