When faced with the challenges thrown at us by the world, our minds can be our greatest asset or a cause of sorrow. To help strengthen and purify the mind, the ancient Rishis (seers) gave us the Gāyatrī Mantra, found in the Vedas. Swami Swaroopananda gives us the background into the origins and deep significance of this popular mantra. Swamiji clearly articulates how we can use it to tune the mind so that the mysteries and the powers of the universe are revealed to us.
