AYURVEDA - The ancient Indian science of health
According to ayurveda and other Indian philosophies like Sankya, Nyaya etc. humans, like the universe, are made up of five elements (called the Mahabhootas) and the Soul. Hence the human body is a microcosm of the universe within itself. In ayurveda the five lements (mahabhootas), in their biological form in the living body are known as doshas, or the humours, namely Vata, Pitta and Kapha. All activities and functions (normal or abnormal) of the body and mind are dependent on the normal or abnormal state of these three doshas in the body.
