Ayurveda is a traditional Indian system of holistic medicine which is widely practiced in India since ages. Although it is considered as one of the many alternative medical systems, its scope is not similar to the scope of modern medical science or other alternative medical systems. Ayurveda, as the name aptly suggests, is a part of vedic literature originated in Bharatavarsha. It is considered to be the उपवेदः । Upaveda of अथर्ववेदः । Atharvaveda with its main focus on maintenance of आयुः। Ayu (life). Ayurveda thus offers the divine methods to achieve ‘Ayu’ and keep away the रोगाः । ‘Rogas’ that create obstacles in the daily activities of human beings.

Ayurveda (Samskrit: आयुर्वेदः) is a traditional Indian system of holistic medicine which is widely practiced in India since ages. Although it is considered as one of the many alternative medical systems, its scope is not similar to the scope of modern medical science or other alternative medical systems. It is important to know that, Ayurveda can not be equated with conventional medical science since the modern medical science deals with the diagnosis and management of diseases affecting only a physical body. However, Ayurveda refers to the knowledge in the scriptures, describing the methods to obtain health and longevity, by preserving health and eradicating the diseases affecting union of body, mind and life energy known as Ayu.

== परिचयः ॥ Introduction ==

Ayurveda refers to the knowledge in the scriptures describing the methods to obtain Ayu. Ayu is a union of 4 elements namely, शरीरम् । Shareeram (Body that has natural tendency to degenerate), इन्द्रीयाणि । Indriyas (commonly known as sense organs and motor organs), सत्वम् । Satva (or मनस् commonly known as mind) and आत्मा Atma (commonly referred to as life energy, consciousness or indestructible spirit). It follows that, purpose, scope and application of Ayurveda is not limited to physical body but to all the 4 elements and the union of these.

Dhaari (धारि), Jeevitam (जीवितम्), Nityaga (नित्यगः), Anubandha (अनुबन्ध) are the terms synonymously used with Ayu. This union is present till the time of death or in other words death is the discontinuation of this union. Therefore Shareeram, Indriyas, Satva and Atma are considered the essential components of Life. <blockquote>शरीरेन्द्रियसत्त्वात्मसंयोगो धारि जीवितम् । नित्यगश्चानुबन्धश्च पर्यायैरयुरुच्यते ।। (Char.

== Emergence of Ayurveda  ==

Every new invention has its roots in some necessity. This the the basis for emergence and advancement for any branch of knowledge. Similarly, even many thousand years ago Ayurveda originated because immense need for this kind of knowledge was felt at that time. This necessity highlights the importance and relevance of knowledge offered in Ayurveda as well as the purpose behind offering the knowledge of life in Ayurveda. Acharya Charaka throws a light on this by writing that, Arogya ( Health and well being) acts as the root of धर्मः । Dharma, अर्थः । Artha, कामः । Kama and मोक्षः। Moksha which results in Shreyas prapti and logngevity. Through the fulfillment of these, life became complete socially, physically, psychologically, intellectually, and spiritually.<ref>Swami Krishnananda, The Heritage of Indian Culture ([https://www.swami-krishnananda.org/heritage/heritage_4.html Chapter 4])</ref> Therefore when in ancient times, common people, Seers and sages performing pious acts experienced impediments due to diseases, the quest for knowledge of life began and this lead to the emergence of Ayurveda many thousand years ago. <blockquote>धर्मार्थकाममोक्षाणामारोग्यं मूलम् उत्तमम् ।। (Char. Samh. 1.1.15)</blockquote><blockquote>रोगास्तस्यापहर्तारः श्रेयसो जीवितस्य च । प्रादुर्भूतो मनुष्याणामन्तरायो महानयम् ।। (Char.

Therefore there is a necessity to know the methods to achieve the desired arogya and eliminate the roga. This necessity also describes the basis of the specific structure of Ayurveda, the aim of Ayurveda and the various concepts that act as basic principles of Ayurveda.

अधिकरणम् । Adhikarna means the substratum or the object for which the entire knowledge is offered.  

Aacharya Charaka has clearly mentioned that knowledge about life offered under Ayurveda is related to the Ayu of त्रिदन्डात्मकपुरुषम् । Tridandatmaka Purusha. It is highly recommended for one to understand the concept of त्रिदन्डात्मकपुरुषम् । Tridandatmaka Purusha described in Ayurveda to identify the scope and application of Ayurveda. The entire knowledge in Ayurveda has been offered for this object known as Tridandatmaka Purusha.

Meaning: Satva (Mind), Atman (Soul) and Shareeram (Body) are the three basic components. The union of these three components form the tripod of life. The entire life depends and sustains on this union. It must be understood that any one of these is not sufficient to uphold the life individually. When each one of these factors supports other and form a union, they develop the ability to sustain the life. When any one of these factors is absent and their union breaks, the life discontinues. Hence each of these 3 factors and their union hold equal importance.

It is believed that the knowledge of Ayurveda was recollected by ब्रह्मा । Brahma and not created. Knowledge of Ayurveda is thus said to be received first by Brahma in meditative state by revelation. It was then passed on to दक्ष प्रजापति । Daksha Prajapati. Daksha Prajapati passed on this knowledge to अश्विनीकुमारौ Ashwinikumaras. Ashwinikumaras are recognized as twin brothers who are renowned physicians of devatas. Various mythological tales in vedas describe complex, innovative surgical procedures and medical treatments performed by Ashwini kumaras.
