In Mandaeism, what is the name of the realm of light where the supreme deity is found?

In Mandaeism, the World of Light is the heavenly realm where the supreme deity is found.

Mandaeism is a living Gnostic religion whose traditional communities have been associated especially with southern Iraq and southwestern Iran. Its cosmology contrasts the World of Light with the material world and the World of Darkness.

The supreme being is often called Hayyi Rabbi, meaning the Great Life. Mandaean religious texts describe divine beings, or uthras, and the soul’s difficult journey through cosmic realms. Ritual purity and baptism in flowing water are central features of Mandaean religious practice.

The World of Light should not be confused with a simple version of Christian heaven. Mandaean cosmology has its own myths, terminology, and sacred literature, although scholars note historical connections with broader Near Eastern and Gnostic traditions.
