The book, titled 'Beyond Reservation', will delve as much into his rich and varied experiences of life as into tribal communities across the world.
Planning to release his autobiography in September, Sangma said the book would give a message to every tribal that they should not be content with reservation. They should instead strive for making a mark on their own.
The book will also give an account of many Northeasterners who made it big in life and made the country proud as well, he said.
