Ayurveda is a medical-metaphysical healing science that focuses on maintaining balance in one's life through diet, lifestyle, and herbs in order to prevent disease and promote health. It views the body as having three main energies - vata, pitta, and kapha - which must be balanced. When these energies are imbalanced, disease can occur. Ayurveda aims to balance the doshas, remove toxins from the body, and restore the free flow of energy in order to cure diseases and maintain well-being. Yoga and adding cosmic energy through various means can heal diseases by up to 80% by balancing energy flow in the body.
