BASIC PRINCIPLE OF AYURVEDA :
Deviating from the known approaches of our times to human body, Ayurveda studies the human body more from a functional point of view. In Ayurveda, human body is not considered just as a mass of organs, systems and tissues; but the complex mechanism of myriad functions taking place both at physical and mental level are evaluated and described.
In order to explain the functional complexity of human body, Ayurveda propounded few basic doctrines. Ayurveda adopted the physics of the "five elements" (mahabhuta); Pṛthvī (earth), Jala(water), Agni (fire), Vāyu (air) and Ākāśa (Sky) — that compose the universe, including the human body.Chyle or plasma (called rasa dhātu), blood (rakta dhātu), flesh (māṃsa dhātu), fat (medha dhātu), bone (asthi dhātu), marrow (majja dhātu), and semen or female reproductive tissue (śukra dhātu) are held to be the seven primary constituent elements – saptadhātu (Saptdhatu) of the body.Ayurvedic literature deals elaborately with measures of healthful living during the entire span of life and its various phases. Ayurveda stresses a balance of three elemental energies or humors: Vāyu / vāta (air & space – "wind"), pitta (fire & water – "bile") and kapha (water & earth – "phlegm"). According to ayurvedic medical theory, these three substances — doṣas are important for health, because when they exist in equal quantities, the body will be healthy, and when they are not in equal amounts, the body will be unhealthy in various ways.
