"Arogyam Sarvadhanal Pradhanam" is a famous quote in Malayalam, which means 'health is the most important wealth'; the slogan upheld for centuries in societies all over the world. Health and longevity have been the major concerns, both at individual and societal levels, from the very beginning of human race. The ancient Greek civilization was one of the first to consider health and illness as related with bodily functions rather than the influence of evil spirits. Ancient philosophers discussed body-mind relationship in the form of conceptualations like monism and dualism. Hippocrates, the 'Father of Modern Medicine', was a firm believer in the dualistic nature of mind and body. According to him, diseases occurred only in body, and mind is free from this process.
