In Ayurveda, you will often hear the term "Dosha". The doshas are energetic forces composed of Ether, Air, Fire, Water and Earth. To make things easier, the elements partner up to create the three doshas, Vata, Pitta and Kapha.
Ether and Air create Vata Dosha
Fire and Water create Pitta Dosha
Water and Earth create Kapha Dosha.
These energetic forces are present in the body and at constant play in our external environment. Each Dosha is predominant in a time of life, a time of year and a time of day. The doshas are more energy than matter, and their energetic force causes specific functions in the body and environment to happen.
