Each Dosha has a primary function in the body:
Vata: Air and air is the moving force within the body. The air moves within the spaces within the body, such as the lungs and colon, and the subtle channels.
Pitta: Fire and Water is the force of assimilation in the body. Fire in the body exists in the form of water, which can be found in acidic fluids.
Kapha: Water and earth are the strength of fluidity and stability in the body. Water in the body is contained within the boundaries of the earth, that is, the skin and tissues.
For a person to have good health, these forces must be balanced within their body. This principle is seen in the scientific concept of homeostasis, where a system regulates its internal environment to maintain a stable and constant condition.
