From antiquity man has made all efforts to maintain his health, promote his longevity and prevent or eradicate the disorders affecting him by all available means. Health according to the definition of the World Health Organization, is a state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity. Recently, a fourth dimension – spiritual health is also added to the definition. The theory of salutogenesis incorporating factors supporting health, as opposed to the conventional approach of pathogenesis to study the factors that cause disease is finally identified by the contemporary system.They still in the basics of finding the facts about health and its preservation.

Swasthasya swaasthya rakshanam aaturasya vikaara prashamanam cha
The word ‘Swastha’ is made of two words, ‘Swa’ and ‘Stha’ which mean the one who stays in self. Swa (Self) refers to the complete personality of an individual which is a conglomeration of four interdependent components namely the body (Shareera), the sensory and motor faculties (Indriya), the mind (Satva) and the soul (Atma). A healthy life necessitates perfect complementary support of all these factors and thus the concept of health according to Ayurveda encompasses physical, mental, sensory and spiritual domains. It is also indicated that a person with Swastha mana (healthy mental state), Prasanna aatmendriya (delighted soul with proper functioning of sense organs) along with Sama dosha (well balanced state of body humours), Sama agni (proper metabolism), Sama dhatu (proportionate body organs and tissues) and Mala kriya (proper elimination of wastes) is perfectly healthy.
