tamasha

In Mandaeism, tamasha or ṭamaša is an ablution ritual that does not require the assistance of a priest. Tamasha is performed by triple immersion in river (yardna) water. It is performed by women after menstruation or childbirth, men and women after sexual activity or nocturnal emission, touching a corpse, or any other type of defilement (ṭnupa). It is also performed after subsiding from unclean thoughts or anger at another person.
