Manda d-Hayyi
In Mandaeism, Manda d-Hayyi or Manda ḏ-Hiia (Classical Mandaic: ࡌࡀࡍࡃࡀ ࡖࡄࡉࡉࡀ, lit. 'the 'Gnosis of Life', 'Knowledge of Life', or 'Knower of the Life'', Modern Mandaic pronunciation: [ˈmendɑtˁ ˈhejji] (mandā-ṭ-heyyī) is an uthra (angel or guardian) sent by the Great Life (Hayyi Rabbi, or the Transcendent God) as a messenger to John the Baptist. Manda d-Hayyi is considered to be the most important uthra, since he is the one bringing manda (knowledge or gnosis) to Earth (Tibil).
