In Mandaean cosmology, Tibil () or occasionally Arqa á¸Â-Tibil (lit. "Tibil-Earth") is the Earth (World) or earthly middle realm. It is separated from the World of Light (alma á¸Â-nhà «ra) above and the World of Darkness (alma á¸Â-hà ¡uka) below by ayar (aether).
To reach the World of Light (alma á¸Â-nhà «ra) from Tibil, Mandaeans believe that need they to establish laufa (connection, union) to be reunited with the World of Light. The laufa is re-created and reconfirmed by priests through rituals such as maá¹£buta (baptism). Upon death, priests must perform masiqta rituals to help the departed soul successfully navigate from Tibil through the various maá¹Âarta (watch-stations) that lie in between, in order to reach the World of Light.
Häberl (2022) considers Tibil to be a borrowing from Hebrew tebel ().
