The Ayurvedic Doshas are the 3 main conditions of the human and define the blueprint for everyone's health and fulfillment.  
The Doshas derive from the Five Elements. Vata is composed of Space and Air, Pitta of Fire and Water, and Kapha of Earth and Water.
You can do a Dosha Quiz online to get a sense of your predominating Doshas or see an Ayurvedic practitioner to get to know more about the Doshas and your individual condition.
