Under Swami Vivekananda’s leadership, Udbodhan ushers in a revolution in Bengali language and literature. Vivekananda, in his letters, urges his brother monks to make use of Bengali language as it is spoken (‘chalita’ Bangla) rather than the ponderous form prevalent at the time. Writings from Vivekananda himself serve to set new examples before the Bengali intelligentsia. Udbodhan, at this stage, is a fortnightly periodical, and would continue thus for the first nine years. From its tenth year onwards, it would become a monthly.
