When Lord Rama stood discouraged on the battlefield, where the magical powers of the demon Ravana seemed impossible to overcome, the great sage Agasthya taught Sri Rama the aditya hrdayam, a hymn to the sun god by which the powers of Ravana would be nullified. Fervent and regular chanting of this hymn even today has great beneficial effects on all levels of our life.\r\nThe subtle meanings hidden in this text are brought out in Swami Tejomayananda's beautiful and lucid commentary in a way that is simple and easy to understand for everybody.\r\n
