Devendranath Tagore started the socio-religious organization "Tattvabodhini Sabha" and its appended journal 'Tattvabodhini'. Before Debendranath joined the Brahmo Samaj, he had organized a Tattvaranjini Sabha at Calcutta. The same Sabha was later known as Tattvabodhini Sabha. The objectives of Tattvabodhini Sabha were to encourage religious inquiries and disseminate the essence of Upanishads.
