[2] Mitra (aged 30) probably met Sri Ramakrishna in 1880, when he went there in company with another prominent householder disciple, Ram Chandra Datta.

Sri Ramakrishna suffered from a terminal throat cancer and had to be shifted to the city of Calcutta.

Mitra bore the entire expenditure of the Cossipore Garden House (about Rs 60 per month), where Sri Ramakrishna spent his last days.

Mitra commissioned the famous oil painting in which Sri Ramakrishna points out the harmony of religions to Keshab Chandra Sen. After the Master left his body, the young devotees of Sri Ramakrishna Paramahamsa were told to go back home.

Their spiritual practices were hindered due to lack of funding, and they had to go through a difficult phase of life.

It was in this phase that Sri Ramakrishna appeared in a vision to Mitra and scolded him for neglecting his children.

[4] According to The Gospel of Sri Ramakrishna, volume 5, Mitra had come to Narendra (Swami Vivekananda) and requested that he find a house where the monastic disciples could reside.

It was also a place where the householder disciples could come and spend some time in solitude, away from the din and bustle - "A cool haven for the unfortunate ones being roasted in the crucible of the world".

Swami Vivekananda and other young disciples began living in an old, neglected house where they focused on their spiritual practices.
