Mandaeism
'Mysteries', i.e. sacraments to help and purify the soul, to ensure her rebirth into a spiritual body, and her ascent from the world of matter.  These are often adaptations of existing seasonal and traditional rites to which an esoteric interpretation is attached.  In the case of the Naoreans this interpretation is based on the Creation story (see 1 and 2), especially on the Divine Man, Adam, as crowned and anointed King-priest.
