It has been speculated that extreme practices of mortification of the flesh may be used to obtain an altered state of consciousness to achieve spiritual experiences or visions. In modern times, members of the Church of Body Modification believe that by manipulating and modifying their bodies (by painful processes) they can strengthen the bond between their bodies and spirits, and become more spiritually aware. This group uses rites of passage from many traditions including Hinduism, Buddhism and shamanism, to seek their aims.
