Other important books include the "Qolastā", the "Canonical Prayerbook of the Mandaeans," which was translated by E.S. Drower. One of the most important works of Mandaean scripture is the "Draša d-Iahia" "the Book of John the Baptist". This book is accessible to both laymen and initiates. There are also many other religious texts such as ritual commentaries, which are generally only consulted by the members of the priesthood.
