NANAK PRAKASH, by Bhai Mahendranath Bose, is a biography of Guru Nanak in the Bengali language. The author was a follower of Keshabchandra Sen, and the followers of Sen used the word Bhai or Rev. Bhai for one another to convey a sense of close kinship and brotherhood. He had lived in the Punjab in 1871 in connection with his missionary work, and had learnt Punjabi and acquainted himself with Sikh literature. He planned to write a life sketch of Guru Nanak and began serializing his account in the Bengali journal Dharmatatva (July 1883). Interrupting the series, he started work on a book Nanak Prakdsh, the first part of which was published in 1885 and the second in 1893.
Chitta Lahu is Nanak Singh\'s first popular novel, published first in 1932, later going into dozens of subsequent editions. Rodu—a juggler—finds a forsaken child behind a bush, whom he adopts and brings up into a young beautiful girl, Sundri—the heroine—comes into contact with young Bachchan Singh—the hero—a devoted idealist very much interested in the reformation of his village. He starts a school in the Gurdwara for giving free education to the children, but due to his villagers\' conservative ideas about untouchability, Sundri is denied this facility. Bachchan Singh teaches her privately and in due course of time, they develop love for each other.
