Devotee of the Master, Narendranath’s classmate, brought up at maternal uncle Ramgopal Basu’s house in Simulia, Calcutta. Swamiji, used to call him “Harmonium”. When 17 or 18 years old first met the Master at Dakshineswar. He being possessed of auspicious signs, the Master would long to see him. After he had married and set up an establishment at Nayanchand Datta Street, he was no longer welcome at Dakshineswar as before, the Master could not “even touch him” (The Gospel of Sri Ramakrishna, p. 493). He had said that worldly life had stripped him of all his good traits, he had lost all his auspicious qualities (Srima Darshan, 7.180). At Cossipore on 1.1.1886 he was one of the two whom the Master had refused to bless in his “Kalpataru” mood. Haramohan received his grace later. Retained his devotion to the Master and cordial relations with other devotees all his life, in spite of having a family. Holy Mother’s worn out bangles remade by him. Evinced much enthusiasm for the printing and publication of the Master’s life and teachings and Swamiji’s lectures. Public interest in Max Muller’s Life of Sri Ramakrishna created by his efforts. It was he who first sold the Master’s photograph to ensure wide publicity. As advised by Swamiji, published the text of the Bhagavad Gita with a translation at a very low price (first 2 annas, then 1 anna, lastly 2 paisas).
His son, Satyacharan, too, was actively engaged in disseminating the Master’s teachings. Latu Maharaj spent the night at his residence for about 5 or 6 months at a stretch from July 1902.
