The practice of study circles has helped introduce large numbers of individuals to the teachings of Baha'u'llah by training tutors to lead discussions using books containing excerpts from the Writings. In India, a single cluster had two thousand individuals become Baháʼís within a six-month period. Within the following year, one thousand of them had finished Ruhi book 2. Similar trends have been observed in Mongolia, Pakistan, Malaysia, Bangladesh among others (all in relatively large numbers); and in Eastern Europe and even Britain (all in somewhat smaller numbers). Many other communities around the world have experienced increased growth and activity since 2000.
