Shira (शिरस् or शिरः)

Shira (शिरस्/शिरः) in Samskrt denotes head. In Ayurveda Shira is known as one of the 3 extremely significant marmas (seats of prana or life energy). A lot of discussion about anatomy and physiology of shiras along with various diseases, pathological processes related to it can be found in Ayurveda literature. While describing all these aspects, the viewpoint of Ayurveda of looking at it is quite different from that of modern/western medicine. The same has been described here.

What is Shira according to Ayurveda

Shiras is also called as uttamanga in Ayurveda. Uttara means top or above and anga means a body part. Thus the part of body located in the topmost position is called as uttamanga. Also, uttama means best or of topmost quality/significance etc. Thus shiras is also known as that body part which is of topmost significance. The reason to call it of topmost significance is as follows,

प्राणाः प्राणभृतां यत्र श्रिताः सर्वेन्द्रियाणि च| यदुत्तमाङ्गमाङ्गानां शिरस्तदभिधीयते||१२|| (Char. Samh. Su 17.12)

Meaning: Shiras (head) is foremost among all organs as it is the part of the body where the life energy and all the vital centers of sensory and motor organs (indriyas) of a living-being are located. (Thus) It is vital (uttama) amongst all the other organs of the body.

Therefore it is clear that Shiras is the seat of all the sensory and motor organs according to Ayurveda. Also being one of the marmas, the life energy is also concentrated at this place. It indicates that, any injury to this part of the body will certainly affect indriyas, pranas and thus the entire life. It is also clear from the above discussion that, ancient Ayurveda scholars very well knew the level of seriousness of neurological disorders, the center of all of which is situated in brain and nerves that are situated inside head.

Anatomy related Shiras

Ayurveda acharyas have counted Shiras in one of the 6 angas knows as Shadangas in Human.

तच्च षडङ्गं- शाखाश्चतस्रो, मध्यं पञ्चमं, षष्ठं शिर इति ||३|| (Sush. Samh. 5.3)

Entrance or Gateway It is also described that Nose is the entry point of shiras. It has been described like follows,

द्वारं हि शिरसो नासा तेन तद् व्याप्य हन्ति तान्||८८|| Cha. Si 9.88

Bahirmukha strotas

Nose is counted as one of the bahirmukha strotasa (channel of passage for various body elements having opening on outer surface of body) along with 5 other such openings situated in head. The other 5 openings are 2 eyes, 2 ears and 1 oral cavity.

Marma

Shiras is known as one of the vital points or marmas.

सप्तोत्तरं मर्मशतं यदुक्तं शरीरसङ्ख्यामधिकृत्य तेभ्यः| मर्माणि बस्तिं हृदयं शिरश्च प्रधानभूतानि वदन्ति तज्ज्ञाः||३|| प्राणाश्रयात्, तानि हि पीडयन्तो वातादयोऽसूनपि पीडयन्ति| (Char. Samh. chi 26.3-4)

Total 107 marmas have been listed by Ayurveda scholars. Among them 3 are extremely significant and vital. Shiras is one of these 3 vital marmas. Since this is the seat of life energy any disturbance in this point will lead to disturbance in life in total.

Bones, Joints, muscles and other structures related to shiras have been discussed in Ayurveda literature at relevant places. Apart from the shiras being a marma itself, simanta, the fine lines of joint between skull bones known as Simantas have also been counted in marmas and effect of injury to them is also described.

The internal structure of pathways of various sensory and motor organs along with seat of prana (life energy) is said to be present in a particular manner in Shiras. Ayurveda acharyas have explain this structure in a simplified way with the help of a similie. They say that, like the radiating spicules of the rays of sunlight that seem to be present far away somewhere from the sun but originate from only one center i.e. Sun, all these Indriyas and prana (life energy) are situated in Shiras but could be seen/manifested anywhere else over the body.

शिरसि इन्द्रियाणि इन्द्रियप्राणवहानि च स्रोतांसि सूर्यमिव गभस्तयः संश्रितानि, (Ch siddhi 9.4)

Effect of head injury

Shiras is one of the 3 most highly important marmas in the body. IT is known that if injury to anyone of these occurs, the person may loose life and can be left severly injured. This has been mentioned by Acharya Charka in the following sutra,

तेषां त्रयाणामन्यतमस्यापि भेदादाश्वेव शरीरभेदः स्यात्, आश्रयनाशादाश्रितस्यापि विनाशः; तदुपघातात्तु घोरतरव्याधिप्रादुर्भावः; तस्मादेतानि विशेषेण रक्ष्याणि बाह्याभिघाद्वातादिभ्यश्च||५|| ??Char. Samh. chi 26.3-4) or (Char. Samh. Siddh 9.5) Menaing: Injury to any of these three vital marma which includes shiras (basti and hriday being other two marma), leads to sudden pain all over body. Destruction of the ashraya(substance) leads to destruction of the ashrita(substrate). Severe disease manifestations occur due to injury, thus shiras must be protected especially from external injury and vata dosha.

Specifically due to head injury certain signs and symptoms can arise and those are as follows,

• Neck stiffness,
• facial paralysis,
• eye disorders,
• mental confusion,
• loss of bodily movements,
• cough,
• breathlessness,
• stiffness of jaw,
• excessive yawning and etc.
