Nityaniranjan Ghosh, more commonly known as Niranjan, was probably born in village Rajahat-Vishnupur ( Bengal), but lived in Calcutta with his uncle. Physically well-built and majestic in appearance, he had somehow become associated with a group of spiritualists who has found in him a very good medium. Having heard about the great spiritual power of Sri Ramakrishna, Niranjan came to Dakshineswar one day.
During this very first visit, the great Master told him, `My boy! If you think of ghosts and spooks, ghost and spook will you become! But if you think of God, divine will be your life. Which do you prefer ?' And this converted him from spiritualism to spiritual life. Though frank and open-hearted, he was subject to loosing temper and consequently all sense of proportions.
Sri Ramakrishna took special care to help him overcome this weakness. Niranjan was one of the few who served the Master day and night during his illness. After his demise he took sannyasa along with others and became `Swami Niranjananda'. He was mainly instrumental in getting the major portion of the ashes of Sri Ramakrishna, to be later interred at the new Math built by Swami Vivekananda. He has a deep devotion for the Holy Mother. Though tender at heart, he could be fiercely stern in the face of hypocrisy. He breathed his last on the 9th may 1904.
