After the death of his wife, Manomohan returned to Calcutta and passed his days talking about the Master and giving spiritual discourses. He also helped with the management of Yogodyana, Ram’s retreat house, where a portion of the Master’s relics had been installed. Although he spent long hours at night in meditation, he would go out early in the morning to visit the devotees’ homes that had been sanctified by the blessed feet of the Master. Then he went to bathe in the Ganges. He had many visions and was in an ecstatic mood most of the time. He one day became overwhelmed when he had a vision of Sri Ramakrishna’s smiling face in the shrine of the Kankurgachi Yogodyana. Once in his meditation he saw the Holy Mother as the goddess of fortune. Another day, while walking on a street in Konnagar, he saw a flock of white cranes slowly disappear in the blue sky. His mind soared to the Infinite, beyond space and time, and he lost outward consciousness. Some of his neighbours carried him home.
Manomohan had tremendous love and respect for the monastic disciples of Sri Ramakrishna. When he heard of Swami Vivekananda’s death, he was brokenhearted, and he somehow sensed that he would not be living much longer either. In 1903, after attending the first celebration of the birth anniversary of Swami Vivekananda at Belur Math, he returned home and never again got up from his bed. The doctors said that he had apoplexy, but according to Swami Premananda, Manomohan was immersed in yoga until the end. The last three days he continuously repeated the name of Sri Ramakrishna. On the final day, 30 January 1903, he lost his voice, but the devotees noticed that his lips were moving, and they began repeating the Lord’s name for him. Immediately the hair on his body stood on end, his prana merged into the Divine, and he was gone. (Source: They Lived with God)
