have been given as examples. In a talk, he once quoted verbatim, two or three pages from Pickwick Papers. Another incident that is given is his argument with a Swedish national where he gave reference to some details on Swedish history that the Swede originally disagreed with but later conceded. In another incident with Dr. Paul Deussen's at Kiel in Germany, Vivekananda was going over some poetical work and did not reply when the professor spoke to him. Later, he apologised to Dr. Deussen explaining that he was too absorbed in reading and hence did not hear him. The professor was not satisfied with this explanation, but Vivekananda quoted and interpreted verses from the text, leaving the professor dumbfounded about his feat of memory. Once, he requested some books written by Sir John Lubbock from a library and returned them the very next day, claiming that he had read them. The librarian refused to believe him, until cross-examination about the contents convinced him that Vivekananda was indeed being truthful. Some accounts have called Narendra a shrutidhara (a person with a prodigious memory). Initial spiritual forays In 1880, Narendra joined Keshab Chandra Sen's Nava Vidhan, which was established by Sen after meeting Ramakrishna and reconverting from Christianity to Hinduism. Narendra became a member of a Freemasonry lodge "at some point before 1884" and of the Sadharan Brahmo Samaj in his twenties, a breakaway faction of the Brahmo Samaj led by Keshab Chandra Sen and Debendranath Tagore. From 1881 to 1884, he was also active in Sen's Band of Hope, which tried to discourage youths from smoking and drinking. It was in this cultic milieu that Narendra became acquainted with Western esotericism. His initial beliefs were shaped by Brahmo concepts, which denounced polytheism and caste restrictions, and a "streamlined, rationalized, monotheistic theology strongly coloured by a selective and modernistic reading of the Upanisads and of the Vedanta." Rammohan Roy, the founder of the Brahmo Samaj who was strongly influenced by unitarianism, strove towards a universalistic interpretation of Hinduism. His ideas were "altered [...] considerably" by Debendranath Tagore, who had a romantic approach to the development of these new doctrines, and questioned central Hindu beliefs like reincarnation and karma, and rejected the authority of the Vedas. Tagore also brought this "neo-Hinduism" closer in line with western esotericism, a development which was furthered by Sen. Sen was influenced by transcendentalism, an American philosophical-religious movement
