According to Maharishi Ayurveda, the key to health lies with the three doshas Vata, Pitta and Kapha. If they are in their natural, individual balanced state, we feel good, efficient, and are very healthy. Maharishi Ayurveda, however, records different therapies to balance the doshas, if they ever become unbalanced..
