According to Ayurveda a human being is composed of five elements, three vital energies – principles (dosha), seven tissues (dhatus) and a large amount of canals (shrotas). Of these five elements – air, space, fire, water and earth – two elements always form the basis of each of the three doshas. The word „dosha“ itself and the names of the three doshas, Vata,Pitta,and Kapha, are Sanskrit words.Dosha – the three principles – interpenetrate everything in nature. Vatta is the energy of movement, Pitta expresses the metabolism and Kapha corresponds to the principle of substance and structures. These energies occur in each of us, only in different amounts in each individual. Each of us has a unique structure of energy – therefore each human being is so unique. The combination of those three doshas comprises our constitution.
