Prana or “vital
energy” operates within the body to maintain life. It performs distinct
functions and manifests in different forms in our physical being. In each case
this specific function is called a "vayu". The word
vayu translates as "wind," connoting all-pervading movement. The
root ‘va’ means “that which flows” – and so a vayu is a vehicle for activities
and experiences within the body, or a ‘force’ that moves in a specific way and
in a specific area of the body. The practices of yoga – both asana and
pranayama – are meant to optimize the
functioning of these vayus as well as bring them under our influence, so that
their energies can be used to uplift ourselves and restore vibrant health.
Though there are 49 prana vayus or types of vayu in the body,
five principle vayus are important for the yogi to recognize. They are Prana
Vayu, Upana Vayu, Samana Vayu, Udana Vayu and Vyana Vayu. Each
govern specific areas of the body, and can be thought of as elemental forces in
the body that are not just the physical, but govern emotional qualities and
mental energies fundamental to physical, mental and emotional well-being.
(see chakras and mudras)
1.
Prana Vayu – while ‘Prana’ is the general name of the life force, the prana vayu
is one of its specific functions. The energy known as prana vayu governs the region from
the throat to the bottom of the heart, corresponding to Jalandhara bandha (see bandhas). The ‘seat’ of the prana
vayu is the heart, and this vayu ensures that the heart goes on beating. It is
associated with the element of air, and has an upward motion associated with the inhalation. When you breathe in, you
feel the ‘lift’ of the breath, which
is the energy of the prana vayu in the upper body. Its movement is upward
in the way the glass is filled with liquid – from the bottom to the top.
The experience is of being filled with energy, which is distinct from the
physical experience of the breath as a flow of air coming in through the nose
or mouth and down to the lungs.The
prana vayu governs assimilation or taking into oneself – as in the process
of inhalation, of swallowing, assimilation through digestion, as well as
the processes of taking in sensory impressions and mentally assimilating information
and experience. It works to maintain the proper temperatureof
the body relative to one’s environment, and sustains one’s vital organs, particularly
the heart. Though
its seat is in the heart, the functioning of the prana vayu can be experienced
in different parts of the body. It gathers at the navel and from there
is distributed throughout the body; yet it can also be experienced strongly
as it moves within the head in practices of pranayama and meditation.
An effective way to focus on the prana vayu is to focus on the sensation
of the breath at the tip of the nose during breathing practices. Another
focus is at the navel. The prana vayu is the energy of the Anahata chakra, the ‘heart’ chakra,
which expresses that energy, summarized in the familiar phrase, ‘open-hearted.’
2.
Apana Vayu – while the prana vayu is the moving force behind the inhalation,
the apana vayu is the moving force behind the exhalation. The apana
vayu is the aspect of the prana that governs the ability to eject or eliminate
what is not needed to the system. Just as with the breath we exhale what
is not needed after assimilating the in-breath, the apana vayu is the force behind
the elimination of waste in general, working in the kidneys, colon,rectum,
bladder and genitals. It is also the moving force in the process ofreproduction
– which essentially moves new life ‘out’ into the world – from insemination
to childbirth. The
healthy functioning of the apana vayu is as vital as that of the prana vayu. If
waste is not eliminated from the body, there is no room for assimilation of
fresh energy, and toxins build up. This slows the body down – and slows us
down on the mental level as well. Without the healthy functioning of apana
vayu, one lacks motivation and determination; one feels lazy, dull and
even confused, indecisive and befuddled.
In
a subtle but vital sense, the apana vayu has much to do with our power of
decisiveness and self-determination, both of which turn upon our power of
choice. Clarity in defining oneself demands decisiveness in eliminating
what doesn’t work for us, what is not needed, or what conflicts with
our highest goals. It’s not surprising that the apana vayu is associated with
the element of earth, and is the energy of the Muladhara Chakra, which is
concerned with having a strong, sure and reliable foundation, especiallyin
fundamental matters of survival.
The
seat of the apana vayu is in the core of the pelvis, and it governs the lower body,
from the navel down through the legs, corresponding to the area in which
we practice Mulabandha. It’s worth noting how our language reflects this
awareness; a person whose decisiveness is rooted in real possibilities and
clear intentions is said to be very ‘grounded’, or to have his "feet on the ground." The clearest expression of decisiveness and self-assertion, in fact, is
to "put your foot down." This kind of language expresses the power of the apana
vayu.
3.
Samana Vayu – this is the power of the metabolism or ‘digestive fire,’ which controls
the functioning of the abdominal organs and glands. It governs the area
between the bottom of the heart and the navel – centralized in the area of
the solar plexus – and its seat is said to be in the navel. It corresponds to the
area in which we practice Uddiyana bandha. While the prana and apana vayus
have to do with assimilation – or taking-in – and self-determination –
or grounding – through choice, the Samana Vayu is concerned specifically with
the power of discrimination.
In
its work with food and digestion, this is the force that separates nutrients from
toxins: when it is not functioning well, one may retain toxins, leading to
shortness of breath and gastric disorders. In the case of the mind, the Apana
Vayu is the power by which to separate out or discern good from bad, which
allows us to assimilate information for the sake of making choices. When
there is a disorder, one can be delusional or of unsound mind. For this
reason, in the yoga tradition the power of digestion is very closely inked
to the power of the mind – particularly regarding discrimination and
judgment.
Samana
vayu is associated with the element of fire. It is associated with the Manipura
chakra, and
when unbalanced, its fiery energy can be used to assert one’s
will or to dominate, especially through anger. In the yoga tradition, anger
is the direct result of a combination of desire, delusion and lack of discrimination.
When the energies and functioning of the vayus are brought into
balance to support clarity of mind, the qualities of Samana Vayu take on
the humble yet expansive self-awareness expressed by the soft opening to the
breath at the back body with Uddiyana bandha. The actions of Uddiyana bandha
and the circulation or prana generally through the body.
4.
Udana Vayu – while apana vayu is concerned with elimination or outward moving energy
in general, udana vayu is the specific force that expels air with the
exhalation in a way that is particularly concerned with speech and the
production of sound. "Udana" is "that which carries upward." It rules the region of the throat and head,
and is seated specifically in the throat. Its function is expressive; it is the
energetic flow that moves upward and out. When udana is unbalanced, speech
is disjointed and one cannot speak or articulate ideas properly.
Imbalances
can also cause shortness of breath and other respiratory problems particularly
associated with the throat, which can have their root in obstacles to
self-expression, or emotional repression. The
area ruled by udana vayu is the head and throat; its energy is particularly stimulated
by Jalandhara Bandha. Udana vayu is related to the element Udana
vayu also governs vomiting, and imbalances in udana can produce nausea or the desire
to vomit. Ether or space, and is associated with this vayu as is the fifth or
throat chakra – the Vishuddha chakra. This upward moving energy continues through the upper
chakra, the Ajna chakra, to the Sahasrara, and is purified during this upward
journey. The feeling of movements of energy in the head during pranayama and
meditation are manifestations
of the movements of udana vayu.
5.
Vyana Vayu – this vayu pervades the whole body, and is a coordinating, connecting
force. It has no specific seat, but rather coordinates all the powers such
as sensory awareness, and runs through the whole network of the 72,000 nadis
or passageways of prana in the body, connecting the functions of the nerves,
veins, muscles and joints. Its function is cohesive and is associatedwith
the element of water. Vyana
vayu is fundamental to making one feel and function as an integrated whole.
Though it governs and coordinates all of the senses as well as the functioning
of all muscles, both voluntary and involuntary, it is felt especially in
the skin. Goosebumps and perspiration, and all of the various actions and reactions
of the skin to the environment are manifestations of Vyana vayu. It functions
at the “surface” or outer boundary of your energy body, much like surface
tension on a drop of water, and is associated with a sense of boundaries through
which we define ourselves and interact with our world.
Within
oneself, Vyana vayu governs our internal sense of coordination and
balance. When unbalanced, one feels uncoordinated and clumsy. Coordination
between mind and body suffers, and one’s own thoughts canbe
disjointed, fluctuating and rambling. Dysfunctions in Vyana vayu can also
lessen our power of sensation.
Though
Vyana vayu itself has no specific seat, it is associatedwith
the energy of the Svadisthana Chakra, In general, Vyana vayu is strengthened by the practice of
hatha yoga asanas. More specifically, because of its association with the
energy and concerns of the Svadisthana Chakra, the subtler energies involved
are enhanced
through Mulabandha. The
energy of the Svadisthana Chakra concerns your sense of self, and sense
of boundaries between yourself and others as you express yourself creatively
in relationships. A healthy sense of boundaries is fundamental to forming
relationships, and work with this chakra concerns the formation of boundaries
and sense of self. Weakness
in the energy of this chakra – which can be due to disorders in Vyana
vayu – leads to a weak sense of self, low self-esteem, problems in forming
relationships, and even problems with the immune system, all of which
concern interaction and exchange with our world and a healthy set of
boundaries.
