Lesson Five — Pranayama

Preparation before technique

The fifth lesson is devoted to prāṇāyāma, the regulation or expansion of vital breath. Before naming techniques, the Gheraṇḍa Saṃhitā discusses place, season, food, purification, posture, and the teacher’s guidance. This preparatory emphasis is one of the chapter’s most valuable features. Breath practice is not isolated from the conditions in which it occurs.

The text recommends a suitable environment and moderation in diet. Its dietary rules reflect historical and ascetic values and should not be turned into universal nutrition advice. Individual needs vary with age, health, pregnancy, medication, culture, workload, and access to food. “Purity” language must never be used to shame bodies or to encourage restrictive eating.

Nāḍī purification

The lesson describes purification of the nāḍīs before stronger breath regulation. Nāḍī Śodhana, alternate-nostril breathing, is often taught today in a gentle form without retention. In the classical subtle-body model, nāḍīs are channels of prāṇa. They should not simply be equated with nerves or blood vessels.

A beginner can practise easy alternate-nostril breathing without forcing the breath: inhale through one side, exhale through the other, reverse, and keep the rhythm comfortable. Nasal obstruction should not be overcome by aggressive pressure. Stop if the practice creates air hunger, dizziness, anxiety, or headache.

Classical ratios and long retentions require supervision. Numbers in a manual are not targets for everyone. Capacity changes from day to day, and competitive breath-holding can cause loss of consciousness.

The eight kumbhakas

The chapter presents eight major techniques, often called kumbhakas: Sahita, Sūryabheda, Ujjāyī, Śītalī, Bhastrikā, Bhrāmarī, Mūrchā, and Kevalī. Terminology varies across texts; the same name may be taught differently in modern schools.

Sahita includes structured inhalation, retention, and exhalation. Sūryabheda emphasizes one nostril and commonly includes retention. Ujjāyī uses gentle narrowing at the throat to create a soft breath sound. Śītalī draws air through a rolled tongue or an alternative tooth position. Bhastrikā uses active bellows-like breathing. Bhrāmarī employs a humming sound. Mūrchā is associated with swooning or faint-like states. Kevalī describes spontaneous suspension beyond ordinary respiratory movement.

What should not be chased

Fainting is not a safe wellness goal. Mūrchā and prolonged retention can reduce cerebral oxygen delivery or alter cardiovascular responses. They should not be attempted from online instructions. Kevalī should not be imitated by forcibly suppressing the need to breathe. A spontaneous quiet pause in a settled breath is different from straining against air hunger.

Rapid breathing such as Bhastrikā can lower carbon dioxide and produce tingling, visual changes, cramping, panic, or fainting. These sensations are physiological effects, not reliable proof of energetic purification. Sit safely, keep initial rounds brief, and stop before symptoms escalate.

Ujjāyī should be soft enough that the throat remains comfortable. Loud constriction, dryness, or strain indicates excess effort. Cooling breaths can irritate sensitive teeth or airways and are not a treatment for fever or heat illness.

Retention and contraindications

Breath retention changes pressure in the chest, abdomen, and head and can affect heart rate and blood pressure. Strong or extended retention may be unsuitable during pregnancy or with cardiovascular disease, uncontrolled hypertension, glaucoma, retinal conditions, seizure disorders, significant lung disease, panic disorder, recent surgery, or hernia. Anyone with medical concerns should seek individualized guidance.

Never practise long retention in water, while driving, standing, or in any place where fainting would be dangerous. Do not combine it with intoxicants. If chest pain, faintness, confusion, severe headache, or unusual shortness of breath occurs, stop and seek appropriate care.

Traditional claims and modern evidence

The chapter attributes extensive effects to prāṇāyāma, including purification, lightness, disease removal, and spiritual realization. Modern studies have explored slow breathing in relation to autonomic regulation, stress, and some clinical outcomes, but the literature varies in quality and technique. Findings about one slow-breathing protocol cannot validate every classical kumbhaka or metaphysical claim.

It is reasonable to say that breathing patterns interact with arousal and attention. It is not responsible to promise that pranayama cures hypertension, anxiety disorders, asthma, infection, or other disease. Breath practice may complement care; it should not replace diagnosis, medication, or emergency treatment.

A safe beginning

Start with posture rather than ratio. Sit supported or lie down. Observe several natural breaths. Gently lengthen exhalation only if it remains comfortable, or practise a short round of alternate-nostril breathing without holds. End with normal breathing and note the after-effect.

Progress is shown by ease, regularity, and recovery—not maximal duration. The classical lesson’s own insistence on preparation supports this conservative approach. Breath is powerful precisely because it should not be handled carelessly.

Source note

Technique names, counts, ratios, and verse numbering differ across editions and lineages. This commentary does not prescribe advanced kumbhaka. Learn strong retentions and rapid methods from a qualified teacher who screens for contraindications and respects medical boundaries.
