The uniqueness of ancient Indian sciences is the Panchamahābhūta theory, which holds good with any physical phenomena in the Universe! The whole universe is made up of 5 elements: Prithvi, Jala, Agni, Vayu, and Akasha. These are found in various combinations of different proportions, thus giving different physical and chemical properties to each substance. To better adopt the Panchamahābhūta theory to deal with the Human Body and the Human Mind, our great ancestors devised the idea of Tridosha theory. Three Doshās make up the entire human body, in various proportions so as to perform various physical and biochemical functions.
