Hinduism has faced numerous situations, threatening its existence. Each time it has found a leader, who rallies the masses to stay united and understand the essence of this great ethos. One such leader was Adi Sankaracharya. At a very young age, he had gained the knowledge of the Vedas, traversed the length and breadth of Bharat and wrote numerous treatise and compositions of his own. Swami Chinmayananda paints vividly the life and work of Adi Sankara, a saint, a visionary and missionary.
