World of Light

In Mandaeism, the World of Light or Lightworld is the primeval, transcendental world from which Tibil and the World of Darkness emerged.

Description

 * The Great Life (Hayyi Rabbi or Supreme God/Monad) is the ruler of the World of Light.
 * Countless uthras dwell in škintas in the World of Light. (A škinta is a celestial dwelling where uthras, or benevolent celestial beings, live in the World of Light. )
 * The World of Light is the source of the Great Yardna (Jordan River) of Life, also known as Piriawis.
 * Ether/Air (ࡀࡉࡀࡓ), which can be thought of as heavenly breath or energy, permeates the World of Light.
 * The Mšunia Kušṭa is a part of the World of Light considered to be the dwelling place of heavenly or ideal counterparts (dmuta).
 * In some Mandaean texts, Tarwan is a part of the World of Light that is described as a "pure land."
 * Water flows from the World of Light to Tibil via hapiqia miia, or cosmic streams of water, also known as Hitpun.

Ascension
When a Mandaean person dies, priests perform elaborate death rituals or death masses called masiqta in order to help guide the soul (nišimta) towards the World of Light. In order to pass from Tibil (Earth) to the World of Light, the soul must go through multiple maṭarta (watch-stations, toll-stations or purgatories; see also Aerial toll house, Arcs of Descent and Ascent, and Araf) before finally being reunited with the dmuta, the soul's heavenly counterpart.

Parallels
The idea has some parallels with the Gnostic concept of pleroma.
