In Mandaeism, a dmuta (Classical Mandaic: ࡃࡌࡅࡕࡀ, lit. 'image', Modern Mandaic pronunciation: [dəˈmutæ]) or dmut is a spiritual counterpart or "mirror image" in the World of Light. People, spirits, and places are often considered to have both earthly and heavenly counterparts (dmuta) that can dynamically interact with each other. A few examples include:

A dmuta dwells in the Mshunia Kushta, a section of the World of Light.

A successful masiqta merges the incarnate soul (ࡍࡉࡔࡉࡌࡕࡀ nišimta) and spirit (ࡓࡅࡄࡀ ruha) from the Earth (Tibil) into a new merged entity in the World of Light called the ʿuṣṭuna. The ʿuṣṭuna can then reunite with its heavenly, non-incarnate counterpart (or spiritual image), the dmuta, in the World of Light, where it will reside in the world of ideal counterparts called the Mšunia Kušṭa (similar to Plato's idea of the hyperuranion).

In Qulasta prayer 43, manda (gnosis) is mentioned as having proceeded from Dmut Hiia (the dmuta of Life). Prayers 170 (the Tabahatan) and 411 in the Qulasta mention Dmut Hiia as the mother of Yushamin.

Similarly, the Qur'an (36:36, 51:49, etc.) mentions that God created everything in "pairs." Related concepts in other religions include yin and yang in Taoism, and the Yazidi belief of there being both a heavenly and earthly Lalish.

Philosophical parallels include Plato's theory of forms.

In the Scroll of Abatur, Dmut Hiia (or Dmut Hayyi) is depicted as a female uthra. The scroll also contains an illustration of Dmut Hiia.
