Life is a continuous process. It has no beginning or end. So, Ayurveda the science which describes about the life and longevity is also considered as eternal. The origin of Universe and all its sciences are credited to Lord Brahma. The knowledge of different fields of life is found in Vedas, which are the ancient literary records of Indian culture. There are four Vedas which are considered as the four mouths of Lord Brahma. They are Rgveda, Sama Veda, Yajur Veda and Atharva Veda. Ayurveda is considered as the Upaveda of Atharva Veda as the maximum information for the promotion of health, prevention and treatment of diseases are described in Atharva Veda. Nowhere in the Vedas the word ‘Ayurveda’ is used, which appears for the first time only in Samhita traditions.
Ayurveda- The knowledge of life – is that which is deal with what is good and what is bad, pleasure and sorrow for life.
BASIC PRINCIPLES OF AYURVEDA
The concreate basic principles of Ayurveda runs its root deep to the cores of Indian philosophies- Nyaya, Vaisesika & Samkhya. These principles highlight a noble concept – man is the microcosm of the macrocosm. When sun and moon controls the activities of the universe, agni and jala principles controls the physiological activities of the body.
BHUTAS

But they have the tendancy to become undergoing increase (Vridhi or decrease ksaya) quantitatively and qualitatively. When they are abnormal, they vitiate their places of dwelling – the dhatus. Because of their tendancy of vitation, they are called Dosas or Vitiators.
Though Dosas are present all over the body. They are found predominantly in areas below the Nabhi (vata between Hrudaya and Nabhi(pitta) and above Hirudaya (Kapha))
