This document provides an overview of the principles of Ayurveda, the ancient Indian system of natural and holistic healing. It describes the three doshas or biological energies - Vata, Pitta, and Kapha - which are derived from combinations of the five elements or mahabhutas that make up all living things. The document explains how to determine one's unique prakriti or constitutional makeup based on their dosha types and imbalance, and how this understanding can be applied to lifestyle, diet, exercise and other practices to maintain health and balance.
