The 5 Pranas – Apana, Udana, and Prana

The 5 Pranas

-Apana, Udana, Prana

As discussed in the previous post on Samana and Vyana, the 5 Pranas or energies are an important aspect of both yogic science and ayurvedic medicine, which as a discipline also aims to achieve and maintain balance between said energies within the mind and body.
Having already come to understand Samana as an energetic movement stemming from the periphery of the body moving inwards and focused in the area of the naval, and Vyana as a circulatory movement to aid with the transportation of energy around the entire physical body, it follows that Apana, Udana, and Prana each travel along their own individual paths too.



Apana can be understood literally as ‘the air that moves away’, therefore signifying the downward and outward energetic pathway which it follows. Apana is associated with the elimination of toxins from the body, and is sometimes considered the definition of our pranic or energetic immune system. Again, this can be understood in terms of physical waste and stools, sweat, carbon dioxide and urine, but also in terms of negative sensory, emotional and mental experiences which prove unpleasant or unsuited to our composition. Centralised in the lower abdomen, Apana not only governs elimination, but also reproduction, providing an instinctual self-sufficiency and replenishing sense of continuity when functioning at the height of it’s potential.


Udana on the other hand is an uplifting force of energy, literally translated as ‘upward moving air’, and is primarily associated with the progression, growth and transformation of the body and mind as they evolve continuously throughout our lives. Physically, Udana aids with balance, growth, and our ability to stand and carry out actions. It also governs speech and is said to stem from an area in the throat, supporting the head and organs associated with our mentality balanced upon the spine. This force of energy being continuously drawn upwards is easily blocked, resulting in stunted growth and stagnancy within our actions and thoughts. Yoga and Ayurveda are used as ways to reopen these pathways and aid the correct flow of Udana throughout the body, unblocking both mental and physical pathways and habits which have hindered our growth and expansion into the world.


Prana in it’s own right serves as the energy of ‘forward moving air’, and although Samana constitutes inward moving energy from the external and its assimilation to the internal,  Prana as a whole deals with the reception of all sensory engagement and its propulsion around the body. Not only does it provide the energy which is necessary for all other pranas to function, but it guides them from its seat in the region of the third eye.

While all 5 Pranas on a physical level have many inherent effects on our body’s reactions and chemical processes, the “receptivity to mental sources of nourishment” (D. Frawley) that can be achieved by incorporating pranayama techniques successfully into one’s yoga practice is an invisible yet exceptional way to achieve and maintain a better mind/body balance and ensure the healthy functioning of the channels through which the pranas travel (nadis). These channels will be discussed  further in another post.

The 5 Pranas – Samana and Vyana

The 5 Pranas
1. Samana and Vyana

Having consumed and digested a certain amount of knowledge on the 5 pranas during my teacher training with Zuna Yoga and also from reading the likes of David Frawley’s ‘Yoga and Ayurveda’, I was inspired to delve deeper and discover more about the subtle differences which exist between them.
‘Prana’ is taken in its most basic form to mean ‘energy’, and we as humans use the five forms of this energy effectively as a means to connect with the universal experiences that are the physicality and consciousness of being. Frawley outlines how the one dominant force of prana within us divides into five separate types which can be categorized according to their movement and direction, and in this blog series we will delve into each pranas individual role and effects within the body in context to the whole.

Prana, Apana, Udana, Samana, and Vyana serve as a means to help us digest and assimilate with all elements of our environment. It’s interesting to consider these actions in terms of elements outside of food and water, something which I had never ever considered before I began to glean an understanding of the pranas.
Outside of the breath, oxygen or air, prana refers to the overall life force which sustains both mind and body and has the power to maintain equilibrium between them.  While food and sustenance are included in the ‘balancing air’ of Samana, which works predominantly in the gastrointestinal tract digesting food,  it also refers to other areas which deal with digestion – namely the digestion of oxygen through the lungs, and the digestion of experiences in the mind. Whether emotional, mental or physical, the correct and balanced functioning of this particular prana is vital to achieving and maintaining a balanced lifestyle.


Moving towards the midline of the body from the periphery inwards, one can imagine the digestive actions of Samana in terms of inhaling and exhaling, in terms of ingesting food, and also in terms of other sensory experiences – sight, sound, smell and touch. These actions all require the assimilation of an external sensation with the internal body as it currently exists, and as such the inward flowing direction of Samana means that it is the primary prana, or energy, required to do so.


A similarly fascinating combination of movements and energy can be observed in Vyana, which aids in circulation and continuation of energy throughout the body. Having established that movement is key to living and maintaining a steady balance, it follows that one of the main pranas must deal with this continuity of motion throughout the body – be it food and water moving through the digestive process, oxygen moving through the lungs, or thoughts and emotions through the mind. This is Vyana’s role.

Cogs and Wheels

The subtle differences between these two pranic energies (Samana and Vyana) is important to be aware of when attempting to understand the power of prana, the combined functioning of which must be broken down to ensure achievement of optimum expression and balance within the body. When Samana’s role ceases after the ingestion of sensory experience, Vyana kickstarts the movement of this externally sourced energy around the internal body. In a way it’s kind of like the cogs in a machine coming into action as their individual role becomes necessary to ensure correct functioning of the whole task. Similarly, for just one of these cogs to be even slightly off or imbalanced in its alignment, the machine does not function to the best of it’s capability.

Having experienced in the past what I have now come to understand as severe imbalances of these energies, manifesting itself within my tiny and self-absorbed world at the time as varying degrees of depression and anxiety, it follows that my fascination with this particular aspect of yoga and energy consumption is ongoing and ever-expanding.

The other 3 prana, Apana, Udana, and Prana itself are similarly linked and we will continue the discussion of them in the next post.
