Synopsis If we look to the history of Dalit movement, it is as old as the birth of the concept of untouchability, which was the darkest spot in Hindu social structure.  Though, Hindu reformists tried their best to fight against this social evil right from the days untouchability was born, the real concern over it came to surface during the freedom struggle, when Mahatma Gandhi and Dr. B.R. Ambedkar fought against it in their own way.  While Gandhi wanted complete eradication of untouchability for emotional integration of Hindu society, Ambedkar was for abolition of Varnashram structure of the Hindu social order.  The book represents a radical departure from the genre of writings that deal with thoughts and works of M.K. Gandhi and B.R. Ambedkar.
