In 1830 he organized the society known as the Brahma Samaj.
The name means literally the "Church of the One God," and the word Samaj, like the word Church, bears both a local and a universal, or an individual and a collective meaning.
The Brahma Samaj maintained a bare existence till 1841, when Babu Debendra Nath Tagore, a member of a famous and wealthy Calcutta family, devoted himself to it.
He gave a printingpress to the Samaj, and established a monthly journal called the Tattwabodhini Patrikd, to which the Bengali language now owes much for its strength and elegance.
In fact the whole Samaj movement is as distinct a product of the contest of Hinduism with Christianity in the 19th century, as the Panth movement was of its contest with Islam 300 years earlier.
