There are no rituals or dogmas, nor any sort of procedures in conversion to Spiritism. The doctrine is first considered as science, then philosophy and lastly as a religion. Allan Kardec's codification of Spiritism occurred between the years 1857 and 1868. Currently there are 25 to 60 million people[citation needed] studying Spiritism in various countries, mainly in Brazil, through its essential books, which include The Spirits Book, The Book on Mediums, The Gospel According to Spiritism, Heaven and Hell and The Genesis According to Spiritism.
