Some religions proselytise vigorously (Christianity, Islam, and HindusimVHP to hold 'ghar wapsi' for 4,000 Muslims in Ayodhya in January, Times of India, 24 December 2014 for example), others (such as Judaism  and Sikhism) do not generally encourage conversions into their ranks. Some faiths grow exponentially at first, only for their zeal to wane (note the case of Zoroastrianism). The growth of a religion can clash with factors such as persecution, entrenched rival religions (such as established religions), and religious market saturation.
