What Is Prana? Life Force and Prana Energy in Yoga
Prana is the Sanskrit term for the life force — the vital energy that yoga describes as animating the body and the mind. The word joins the prefix pra-, meaning forth, with the root an, to breathe or to live. Breathing practices are called pranayama for that reason: prana plus ayama, meaning to extend.
This page covers what the term means, how the tradition relates prana to the breath, the five things it describes doing with prana, and the two breathing practices taught to new students.
What prana means
In this system prana is not a single substance but the name given to whatever animates a living body. The tradition holds that it is present throughout nature and that it varies in concentration — fresh food, open air and living things are described as carrying more of it than processed or enclosed equivalents.
It is worth being clear about the register. This is a descriptive model belonging to yoga and Ayurveda, used to organise and teach practice. It is not a structure described by modern physiology, and nothing here is a claim about preventing or treating illness.
Prana and the breath are not the same thing
The breath is the most visible expression of prana, which is why the two get conflated. In the tradition's own account prana extends beyond respiration to everything the body does — digestion, circulation, and mental activity included.
That connection has one plainly observable side. Breathing and mental state move together: short and quick when agitated, long and slow when settled or concentrated. Yoga works that relationship in the other direction, adjusting the breath deliberately to act on the state of mind. Pranayama is where that happens.
The five things the tradition does with prana
Across the teachings this comes down to five verbs. They are usually taught in this order, and the money analogy that follows is the tradition's own.
1. Increase — Practices held to add to it: the postures, the breathing exercises, rest, fresh food, time outdoors.
2. Conserve — Earning is not enough if it is spent as fast. The teaching compares this to income against savings: a week of practice can be undone in an afternoon.
3. Balance — Described as the distribution rather than the amount. Someone may be highly active mentally and inert in another respect; the tradition frames this as the imbalance of ha and tha, the two syllables in hatha.
4. Channel — Directing it into use. The teaching holds that prana behaves less like a stored quantity and more like a capacity that grows with use.
5. Purify — Making it subtler, described in the tradition's vocabulary as more sattvic. The analogy given is a hundred single notes against one note of the same value: the same amount, in a more concentrated form.
The pair worth noticing is the second and third. Both say that the quantity of energy is not the whole question — how it is kept and how it is distributed matter as much, which is why the practices are as concerned with rest and diet as with effort.
The five elements
One teaching organises the sources of prana by the five elements. The associations are set out here as the tradition states them, without instructions attached.
- Earth — contact with the ground and with growing things; fresh, unprocessed food.
- Water — clean water, fresh fruit, cleanliness.
- Fire — sunlight, warm food, digestion.
- Air — open air and the breathing practices. This is the element pranayama works with directly.
- Ether — described as the subtlest of the five, and associated with thought, the sung practice, and the company one keeps.
The sequence runs from the most tangible to the least, which is also the order in which the five points of yoga move: from posture and diet through breathing to the mind.
Where prana sits in the Five Points of Yoga
Proper breathing is the second of the five points the Sivananda system is built on, alongside the postures, relaxation, diet, and positive thinking with meditation.
Its position in a class is specific and often surprises people: pranayama comes before the postures, not after. A ninety-minute open class runs initial relaxation, then the seated breathing practices, then Sun Salutations, leg raises, the twelve basic postures, and a guided final relaxation. The full sequence is described in the beginner's guide.
The two breathing practices taught first
Kapalabhati
A series of short, active exhalations produced by contracting the abdomen, with the inhalation left passive as the abdomen releases. The exhalation is the working phase; the inhalation is not forced. Practised in rounds with a rest between them.
Anuloma Viloma
Alternate nostril breathing. The breath is drawn in through one nostril, retained, and released through the other, then repeated from the opposite side — one such cycle is a round. It is taught with a set ratio between inhalation, retention and exhalation, and the number of rounds is built up over time.
The left and right distinction rests on the tradition's account of nadi, the channels prana is said to move through: Ida and Pingala are associated with the left and right sides, and Sushumna with the central line.
Learn these in a class first
Kapalabhati is normally avoided during pregnancy and with uncontrolled high blood pressure, heart conditions, hernia, epilepsy, or recent abdominal surgery.
Retention in Anuloma Viloma is built up gradually. Both are simple to perform and easy to perform wrongly, which is the reason they are taught in person where the count can be corrected. This page is general information, not medical advice.
Frequently asked questions
What does prana mean?
Life force, in Sanskrit. The word combines pra-, forth, with an, to breathe or live. Pranayama — the breathing practices — takes its name from it.
Is prana the same as breath?
No. The breath is its most visible expression, but the tradition extends prana to everything the body does, mental activity included.
Is prana the same as qi?
They come from separate systems and are better not treated as equivalents. Both describe a vital energy moving through the body, but the categories and the techniques differ. Prana belongs to yoga and Ayurveda.
How is prana increased?
The tradition names the postures, the breathing practices, rest, fresh food and time outdoors, and places equal weight on not dissipating what is there. Increase and conserve are taught as a pair.
Do I need to practise postures before pranayama?
In a Sivananda class the order is the other way round: the breathing practices come before the postures.
Can I practise the breathing exercises at home?
Both are taught in class first, because the count and the technique need correcting in person. The cautions above apply at home as much as anywhere.
Pranayama in class
Kapalabhati and Anuloma Viloma are on the timetable of every open class, at the start of the session. No previous experience needed.
