Ayurveda is the oldest surviving complete medical system in the world. Derived from its ancient Sanskrit roots - ‘ayus' (life) and ‘ved' (knowledge) – and offering a rich, comprehensive outlook to a healthy life, its origins go back nearly 5000 years. To when it was expounded and practiced by the same spiritual rishis, who laid the foundations of the Vedic civilisation in India, by organising the fundamentals of life into proper systems.

The main source of knowledge in this field therefore remain the Vedas, the divine books of knowledge they propounded, and more specifically the fourth of the series, namely Atharvaveda that dates back to around 1000 BC. Of the few other treatises on Ayurveda that have survived from around the same time, the most famous are Charaka Samhita and the Sushruta Samhita which concentrate on internal medicine and surgery respectively. The Astanga Hridayam is a more concise compilation of earlier texts that was created about a thousand years ago. These between them forming a greater part of the knowledge base on Ayurveda as it is practiced today. The art of Ayurveda had spread around in the 6th century BC to Tibet, China, Mongolia, Korea and Sri Lanka, carried over by the Buddhist monks travelling to those lands. Although not much of it survives in original form, its effects can be seen in the various new age concepts that have originated from there.

It also gives rise to cosmic consciousness, which is the universal order that prevades all life. Individual intelligence, as distinct from the everyday intellectual mind, is derived from and is part of this consciousness. It is the inner wisdom, the part of individuality that remains unswayed by the demands of daily life, or by Ahamkara, the sense of `I-ness’.

A Sanskrit word with no exact translation, Ahamkara, is a concept not quite understood by everyone as it is often misleadingly equated to `ego’. Embracing much more than just that, it is in essence that part of ‘me’ which knows which parts of the universal creation are ‘me’. Since ‘I’ am not separate from the universal consciousness, but ‘I’ has an identity that differentiates and defines the boundaries of `me’. All creations therefore have Ahamkara, not just human beings. There arises from Ahamkara a two-fold creation.

The first is Satwa, the subjective world, which is able to perceive and manipulate matter. It comprises the subtle body (the mind), the capacity of the five sense organs to hear, feel, see, taste and smell, and for the five organs of action to speak, grasp, move, procreate and excrete. The mind and the subtle organs providing the bridge between the body, the Ahamkara and the inner wisdom, which three together is considered the essential nature of humans.

The second is Tamas, the objective world of the five elements of sound, touch, vision, taste and smell – the five subtle elements that give rise to the dense elements of ether or space, air, fire, water and the earth – from which all matter of the physical world is derived. And it is Rajas, the force or the energy of movement, which brings together parts of these two worlds.

Ayurveda therefore is not simply a health care system but a form of lifestyle adopted to maintain perfect balance and harmony within the human existence, from the most abstract transcendental values to the most concrete physiological expressions. Based on the premise that life represents an intelligent co-ordination of the Atma (Soul), Mana (Mind), Indriya (Senses) and Sharira (Body). That revolves around the five dense elements that go into the making of the constitution of each individual, called Prakriti. Which in turn is determined by the vital balance of the three physical energies - Vata, Pitta, Kapha and the three mental energies - Satwa, Rajas, Tamas. Ayurveda thus offers a unique blend of science and philosophy that balances the physical, mental, emotional and spiritual components necessary for holistic health.
