What is "adbhutananda"

Adbhutananda (died 1920), born Rakhturam, was a direct monastic disciple of Ramakrishna, a mystic of nineteenth century Bengal. He is familiarly known as Latu Maharaj among the followers of Ramakrishna. Adbhutananda was the first monastic disciple to come to Ramakrishna. While most of Ramakrishna's direct disciples came from the Bengali intelligentsia, Adbhutananda's lack of formal education made him unique amongst them. He was a servant boy of a devotee of Ramakrishna, and he later became his monastic disciple. Though unlettered, Adbhutananda was considered as a monk with great spiritual insight by Ramakrishna's followers, and Vivekananda regarded him as "the greatest miracle of Ramakrishna".
