**Easy Definition for Beginners** The [Dosha definition](https://www.harithaayurveda.com/blogs/dosha-in-ayurveda) in Ayurveda describes dosha as a functional energy that governs the body and mind. It is not a physical organ but a principle that controls how systems work together. Doshas influence digestion, immunity, circulation, and emotions. Each dosha has qualities like hot, cold, heavy, or light, which affect the body’s response to food and weather. When these qualities increase or decrease too much, imbalance occurs. Ayurveda focuses on preventing illness by maintaining dosha balance through diet, herbs, lifestyle changes, and therapies rather than treating disease only after it appears.
