Although etymologically related to the Canaanite word yarden (Hebrew: ירדן), or the Jordan River, a yardna in Mandaeism can refer to any flowing river.[3] Traditionally, these were typically the Euphrates (Mandaic: Praš), Tigris (Mandaic: Diglat), and Karun (Mandaic: ʿUlat)[4] rivers. The Euphrates is called Praš Ziwa (ࡐࡓࡀࡔ ࡆࡉࡅࡀ; pronounced Fraš Ziwa) in the Ginza Rabba.[5] In Mandaean scriptures, the Euphrates is considered to be the earthly manifestation of the heavenly yardna or flowing river (similar to the Yazidi concept of Lalish being the earthly manifestation of its heavenly counterpart).[6]
There are two types of sacramental water used for Mandaean rituals, namely mambuha ("drinking water") and halalta ("rinsing water"). Both are drawn directly from a yardna.[3]
Uthras
Mandaean texts mention various uthras watching over yardnas.
