Sira Sharira (Shareera) That means, Varieties And Significance


By Dr Raghuram Y.S.MD (Ay) & Dr Manasa, B.A.M.S
The phrases Sira, Dhamani and Srotas are used interchangeably in Ayurveda. All of those buildings transport one thing or the opposite from one a part of the physique to the opposite. The outline of every of those reveals that they’re totally different buildings serving totally different features within the physique. Sira Sharira i.e. examine of siras is equated to angiology therefore, thought of as ‘Ayurveda Angiology’.

Definition of Sira

In line with Atharva Veda  – ‘Siras are these which carry impure blood. They’re really referred to as Hira as a substitute of Sira. These of which carry pure blood are referred to as dhamani’.

With this reference we perceive that the sira is vein and dhamani is artery. However, Grasp Sushruta’s clarification of sira encompasses many buildings i.e. veins, arteries, lymphatic and nerves.

Grasp Charaka says ‘Since there’s motion of blood in these buildings they’re referred to as as sira’. Sarana means ‘to go’ or ‘to maneuver from one place to the opposite’. 

Grasp Gangadhara tells ‘Sarana means the motion of rasa and different tissues. The construction during which such motion takes place is named as sira’. Right here we get a doubt since Gangadhara has particularly talked about ‘rasadinam gamanat’ i.e. many extra tissues apart from blood circulation or transfer in these siras. However the buildings which carry all of the tissues are referred to as as srotas. Sira and Srotas have been used as synonymous to one another by many authors. Dhamani can be a synonym of sira and srotas. The identify of the identical construction may be sira, dhamani or srotas relying on what sort of perform they’re rendering. However they’re anatomically and functionally totally different since, they’ve been described individually regardless of getting used interchangeably.

One other truth is that the srotas carry the tissues that are within the technique of transformation and siras carry the fashioned blood and lymph / plasma tissue.

Origin, Root, Variety of Siras

Grasp Sushruta says that there are a complete variety of 700 siras within the human physique. The features of the siras are to supply diet to each a part of the physique. Subsequently they’re unfold out in the complete physique. This has been defined with appropriate examples –

Understanding the features of Siras with examples of water carriers and small channels – Similar to the water carriers sprinkle water to each plant within the backyard / grove and similar to the small canals / channels carrying water convey water to each a part of the sector and nourish the crops therein, the siras unfold all via the physique and nourish all buildings therein.

Understanding the construction of sira with examples of veins of leaves – Similar to the veins and venules are unfold over the leaf, the siras unfold all via the physique. They department and re-branch as they unfold out.

Root of origin of siras – Umbilicus is the basis of origin of siras. After taking their origin within the navel the siras unfold upwards, downwards and side-wards. They unfold all through the physique from the navel. This can be the reason in relation to fetal circulation and restricted to that a part of clarification from the fashionable perspective. The life ingredient of all residing beings is situated within the navel. And the navel exists on the idea of the life parts linked to it. The navel is surrounded by the siras in a approach just like the spokes of a wheel which encompass the axle of the wheel. From this instance we perceive that the navel is the axle and the siras taking their origin from the navel and likewise surrounding the navel kind the spokes of the axle. Thus, the navel and the siras round it seem like the wheel and its spokes. Similar to the axle depends on the spokes and spokes on the axle, the life ingredient is situated within the navel and the supply of existence of the navel is the pranas i.e. life parts linked to it.

The prana which is linked to the navel on this context needs to be understood as ‘blood’. Siras convey blood and blood is a crucial life ingredient, we stay when the blood flows uninterruptedly to each nook of the physique. The navel is surrounded by siras additionally signifies that the navel is surrounded by blood – described as life ingredient on this context. 

Once we have a look at the fetal circulation we perceive that the blood circulation to and from the kid occurs via the newborn’s navel. The diet to the newborn from the mom passes via the placenta, umbilical twine and navel of the kid to the kid. This has to occur uninterruptedly because the child within the womb doesn’t have its personal circulation and oxygenation system which is working. The newborn and sustenance of its life and development of the newborn is completely depending on the mom and the mechanism of fetal circulation which connects the mom with the newborn. If this connection will get reduce off from the newborn’s navel or if the fetal circulation is hampered it could end result within the demise of the kid within the womb. If the kid has inadequate blood and diet provide via the fetal circulation, the kid would possibly take start with many abnormalities. From this angle the navel may need been mentioned to be the basis and origin of siras. Subsequently this description is from the embryological perspective.

Why solely 700 siras – 700 siras needs to be understood because the bigger branches of siras. They might additional department into smaller branches as they unfold all through the physique and thus 1000’s of siras are fashioned.

If we fastidiously observe the meanings of the above talked about 3 examples, the examples clarify 3 totally different sorts of siras.

Sl No Instance describing siras Kind of sira referred to by the instance
1 Water service Bigger siras – most likely the 700 siras talked about by Sushruta
2 Channels / small canals conveying water to the crops / crops within the fields The secondary branches of the above mentioned 700 siras, siras of reasonable measurement – measurement of those siras are smaller than the bigger siras
3 Veins and venules of the leaves The tertiary branches of the siras, the smallest branches which most likely department out from the reasonable sized siras talked about above

Observe – If sira is taken as vein, the examine needs to be accomplished in a reverse approach. Analogy / instance 3 explains the formation of venules on the capillary degree, becoming a member of to change into the secondary tributaries (analogy / instance 2). These secondary tributaries be part of collectively to change into bigger veins (water service instance / analogy 1) which drain into the center. If we have to use the phrase artery for sira we are able to additionally think about the phrase ‘branches’ as a substitute of ‘tributaries’ and  their distribution may be understood in a descending approach i.e. analogy 1 to analogy 3.

Relation of siras with features of the physique and physique components – Necessary privileged features like extension, flexion, speech, sleeping awakening and so on are below the management of siras. This implies to say that if the siras and their branches prolong to each a part of the physique and supply them with the wanted diet the talked about features will probably be doable in an unhampered approach. The phrase ‘adi’ which suggests ‘and so on’ explains that many features of the physique are depending on how the siras and their branches are distributed in the complete physique.

The truth is once we rely all of the siras talked about by Sushruta that are distributed within the head, neck and buildings therein we’ll get 262 siras i.e. 98 siras greater than the quantity talked about by Sushruta within the earlier a part of the identical chapter. The rationale for that is unknown. There is perhaps repetition of some siras.

What are Siras?

Understanding the time period sira from the definition and origin perspective – Siras are hollowed out buildings which carry plasma and blood tissue in them (in accordance with the definition). The siras convey rasa and blood to totally different components of the physique. The time period sira is used as synonym or interchangeably with dhamani and srotas that are the opposite buildings that are associated to transportation and distribution of significant components within the physique together with these supplies wanted for tissue development. The origin of siras is claimed to be the umbilicus. This clarification is restricted to the ‘embryological clarification of fetal circulation’. The outreach of siras are ‘total physique’ since sarana, the perform of sira is defined as ‘transportation of blood from one place to the opposite’.

Sira understanding from the attitude of similes given within the treatises – The water service simily explains the siras nourishing the buildings. That is the outward circulation of nourishing materials which may be doable solely via arteries as a result of veins deliver again the blood to the center. The definition of siras additionally tells the identical. Sarana means to move or issues within the siras shifting to totally different components of the physique. The leaf analogy too explains the outwards branching of siras and their distribution all via the physique. This may both be branches of arteries or nerves. However nerves should not hole and don’t carry something. All these analogies are given by Sushruta in the identical context, one after the opposite.

If siras are taken as veins and dhamanis (resulting from their pulsation property) as arteries, the water service analogy explains bigger veins, the ‘channels within the discipline’ analogy explains the secondary tributaries fashioned by the becoming a member of of smallest veins and in flip be part of collectively to change into the bigger veins. The ‘veins and venule on the leaf’ analogy explains the tributaries on the origin i.e. venules on the capillary degree. These be part of to kind the secondary veins or intermediate veins.

From the useful side of siras – the features like extension, flexion, speech, sleeping, awakening and so on are below the management of the nervous system and siras must be thought of as nerves. If these features are mentioned to be going down resulting from correct blood provide to the organs associated to those features, then siras must be thought of as arteries.

From the attitude of dosha clever classification of siras – The features of vata, pitta, kapha and blood are additionally carried about by the balanced presence of those elements in siras and put into circulation via the identical siras. These features embrace mental features, features of thoughts and physique, nourishment, enrichment of tissues, colour, complexion, lubrication, integrity, immunity, digestive features, energy, reflection and so on . These features relate to the features of the nervous system / nerves or arteries.

From the attitude of colour of the siras – Siras carrying vata are reddish brown and the outline resembles the nerves. Vata features are carried via nerves and the nervous system. Siras carrying pitta are mentioned to be blue in colour and resemble the construction of veins. Siras carrying kapha are white in colour and resemble the construction of lymphatics. Siras carrying blood are shiny crimson and clarify the construction of arteries and arterioles. Many consultants subsequently opine that siras should not simply veins. The phrase sira needs to be understood contextually. Ayurveda masters have given a generalized identify to many buildings as sira via which one thing is conveyed from one place to the opposite and the time period encompasses all of the buildings talked about on this paragraph.

From the siravedha perspective – Siravedha i.e. venesection which is part of bloodletting remedy in Ayurveda factors in direction of the time period sira as vein as a result of artery or nerve can’t be punctured. Grasp Sushruta has enlisted some siras (described above) which shouldn’t be punctured as part of surgical course of or vensection remedy / bloodletting remedy. These siras is perhaps the higher veins or necessary arteries or nerves or congruence of those buildings at some extent making a marma i.e. important construction or level whereby it shall not be punctured. The opposite siras may be punctured and therefore the ‘may be punctured’ part of siras are superficial veins which may be punctured for remedy. The siras which fall below the class of ‘to not be punctured’ siras could comprise arteries, deeper veins, bigger veins, nerves or marma factors.
