In India, Charak Samhita, a famous treatise on Ayurveda, classifies people into the categories of vata, pitta and kapha on the basis of three humoural elements called tridosha. Each refers to a type of temperament, called prakriti (basic nature) of a person. Apart from this, there is also a typology of personality based on the trigunas, i.e. sattva, rajas, and tamas.
