What Ancient Yoga Texts Say About Breathing: A Guide to the Sources

By Breathwork Studios · Updated March 2026 · 10 min read

Pranayama is not a modern invention. The breathing techniques practiced today with scientific understanding of HRV, CO₂ tolerance, and the autonomic nervous system were first described in Sanskrit texts composed between 400 and 1500 CE — and some practices draw on traditions older still. Understanding the source texts contextualises the practice in a way no modern guide can: these were observations from sustained, serious practitioners over many generations, refined by a tradition of direct transmission from teacher to student.

This article surveys the four primary classical sources for pranayama: the Yoga Sutras of Patanjali, the Hatha Yoga Pradipika, the Gheranda Samhita, and the Shiva Samhita.

The Yoga Sutras of Patanjali (circa 400 CE)

The Yoga Sutras are the philosophical foundation of classical yoga — 196 aphorisms in four chapters covering the nature of mind, the practice of yoga, the supernatural powers (siddhis) that may arise from advanced practice, and liberation (kaivalya). Patanjali did not invent yoga — he systematised and organised a tradition that already existed.

What the Sutras say about pranayama

Pranayama is defined in sutras 2.49–2.53. Key teachings:

• Sutra 2.49: Pranayama is "the regulation of the movements of inhalation and exhalation" (tasmin sati shvasa prashvasayor gati vicchedah pranayamah). It is described as following from asana — the fourth limb following the third.
• Sutra 2.50: Breath is modified by place, time, and count — external (bahya), internal (antara), or restrained (stambha). It becomes prolonged and subtle.
• Sutra 2.51: There is a fourth pranayama that transcends the external and internal — a hint at the more advanced states where deliberate technique gives way to natural, effortless breath suspension.
• Sutra 2.52: Pranayama removes the covering of inner light (tata kshiyate prakashavaranam) — the mental obscurations that veil direct perception are thinned by pranayama practice.
• Sutra 2.53: The mind becomes fit for dharana (concentration) — Patanjali explicitly states that pranayama prepares the mind for the inner practices.

The Sutras are deliberately sparse on technique — Patanjali assumes the reader has access to a living teacher. What they provide is the philosophical framework: pranayama as a bridge between physical and mental practice, and as a tool for removing the mental coverings that obscure clarity.

The Hatha Yoga Pradipika (15th century CE)

Composed by Swatmarama, the Hatha Yoga Pradipika (HYP) is the most practically detailed of the classical texts — a manual for practice rather than a philosophical treatise. Its four chapters cover asana, pranayama, mudra and bandha, and samadhi. Chapter Two is devoted entirely to pranayama and is the primary source for most classical techniques still practiced today.

What the HYP says about pranayama

The HYP opens its pranayama chapter with a remarkable statement: "When the breath wanders, the mind is unsteady. When the breath is still, the mind is still" (HYP 2.2). It then provides extensive practical guidance:

• Nadi purification first: The HYP insists on nadi shodhana (nadi purification through alternate nostril breathing) before any other pranayama — the channels must be clean for other techniques to work safely. It prescribes three months of intensive Nadi Shodhana before advancing.
• The eight kumbhakas: The text describes eight named breath retention practices — Surya Bhedana, Ujjayi, Sitkari, Sitali, Bhastrika, Bhramari, Murccha (swooning breath), and Plavini (floating breath). Each is described with its technique, benefits, and appropriate use.
• Signs of progress: The HYP describes specific signs indicating that pranayama is working — perspiration, trembling, and lightness in early stages; the ability to remain still for long periods; and ultimately the cessation of ordinary breathing in deep states.
• Diet and lifestyle: The text is specific about conditions that support pranayama: moderate, wholesome food; avoidance of overexertion, excessive talking, and late nights; and a quiet, clean practice space.
• Kumbhaka and Kundalini: The HYP is explicit that kumbhaka (breath retention) combined with bandhas is the primary mechanism for awakening Kundalini — the text is written with this as its explicit goal.

The Gheranda Samhita (late 17th century CE)

The Gheranda Samhita is a dialogue between the sage Gheranda and his student Chanda Kapali. It describes a seven-step Ghatastha yoga (yoga of the body) that differs somewhat from Patanjali's eight limbs. Its third chapter is devoted to pranayama.

What the Gheranda Samhita says about pranayama

The Gheranda Samhita describes five conditions necessary for successful pranayama practice:

• A suitable place — a small, clean room free from insects, with a door but no windows
• A suitable time — spring or autumn, when the temperature is neither too hot nor too cold
• Regulated diet — wholesome food in moderate quantities
• Nadi purification first — consistent with the HYP
• Three preparatory practices — the Shatkarmas (cleansing practices) before pranayama is introduced

The Gheranda Samhita also describes eight kumbhakas, largely consistent with the HYP, and is particularly detailed on the kumbhaka that involves Khechari Mudra (tongue-rolling into the nasopharynx). It attributes extraordinary longevity and resistance to disease to advanced practice.

The Shiva Samhita (15th–17th century CE)

The Shiva Samhita is presented as teachings of Shiva to his consort Parvati — a Tantric text that integrates Hatha Yoga with Vedanta philosophy. Its fifth chapter covers pranayama in the context of a broader discussion of nadis, chakras, and the ultimate nature of consciousness.

What the Shiva Samhita says about pranayama

The Shiva Samhita describes 350,000 nadis (other texts give 72,000 — the specific numbers are symbolic rather than literal) and emphasises that without purification of the nadis, pranayama cannot produce its intended effects. It describes four stages of pranayama practice:

• Arambha — the initial stage, characterised by perspiration, trembling, and a feeling of lightness
• Ghata — the second stage, where the inner sound of the breath becomes audible in meditation
• Parichaya — the third stage, where prana enters Sushumna and the practitioner gains control over the sense organs
• Nishpatti — the fourth stage, mastery — where the practitioner transcends ordinary physical limitations

The Shiva Samhita also contains detailed descriptions of the 84 classical asanas, the chakra system, and the stages of Kundalini awakening — situating pranayama within a comprehensive system of subtle body cultivation.

What the Texts Agree On

Despite differences in emphasis and detail, all four texts agree on several key points:

• Nadi purification through Nadi Shodhana is foundational and must precede advanced practice
• Kumbhaka (breath retention) is the most powerful element of pranayama
• Bandhas are applied during retention to direct and contain prana
• Diet, lifestyle, and teacher guidance are prerequisites for safe advanced practice
• Pranayama prepares the mind for meditation and the deeper states of yoga
• The breath and the mind are intimately connected — stilling the breath stills the mind

This consistency across texts composed centuries apart and in different traditions suggests these observations were empirically derived — the products of extensive practitioner experience rather than purely doctrinal elaboration.
