Even though Advaita as a doctrine was extracted from the Upanishads by Sree Sankara, the 8th century sage and philosopher, it was Sree Narayana Guru who transformed the Advaita philosophy from an elite theoretical doctrine into a relevant principle of practical applicability. Thereby, he expanded its scope to effect phenomenal social changes, and enabled one of the most profound yet bloodless social revolutions in history. As a social reformer, Sree Narayana Guru's impact was unmatched in history. Those who had been denied basic human rights for centuries were able to experience dramatic changes in their lives due to the awakening caused by Guru's teachings on self-improvement and self-empowerment. The focus on education, organization and entrepreneurism that he insisted on to secure freedom, strength and prosperity remains an ideal and timeless model for peaceful changes in the condition of suppressed and marginalized people of any society. The defining theme of his vast philosophical writings is the oneness of human race transcending all peripheral differences. His earnest call for mutual respect and understanding among all religions is a lesson that is still to be learned. The intention of this well-researched and lucidly-written book is introduce to readers the illustrious life of the sage, Sree Narayana Guru, who emerged as the conscience of Kerala in the twentieth century.
