The credit for Kerala's transformation from a primitive, caste-ridden society to a State that boasts of human development indices that are higher than most parts of the country must go in some measure to a reform movement that swept through the region in the 19th and the early 20th centuries. One of the most prominent faces that brought about the change was Sree Narayana Guru, a monk, an exponent of Advaita, who channelled his spiritualism into social action. Sree Narayana Guru: The Sage of Sivagiri, a special volume brought out by The Hindu, pays tribute to the enduring legacy of this great man.
