Pitta means, "That which digests things." The elements that govern Pitta are fire and water. Think of Pitta as the body's fire or metabolism. A famous Ayurvedic text defines the characteristics of Pitta dosha: hot and a little unctuous; sharp, burning; liquid and acidic; always flowing in an uncontrolled manner; pungent and sharp. Pitta contains fire, but it also contains water. It is the source of the flame, but not the flame itself.
Pitta is a power created by the interaction of water and fire. These forces symbolize transformation. For example, too much fire and too little water will cause the evaporation of the water. Too much water will result in the fire being put out. - excerpted from: Dipreg.com
