Amritlal Vithaldas Thakkar, popularly known as Thakkar Bapa, was a social worker who worked for the uplift of the downtrodden and tribals. Very early in life, he gave up a lucrative job only to devote his time to the service of the oppressed. Beginning from his home state Gujarat, he soon covered the whole country in providing relief - be it flood, famine, earthquake, or just economic and social backwardness. India owes it to the tireless efforts of this man that the provisions included in the Constitution of India for safeguarding the interests of the tribals and their development could become a reality. The author of this book, Viyogi Hari, a Gandhian and a prominent Hindi writer was also a constant companion of Bapa.
