The Khamnung Leipaak or Leinung is the netherworld or the land under the surface of the human world in Meitei mythology and religion. It is the kingdom ruled by Thongalel, the god of death. It is the place where the souls of the dead people used to go. According to ancient Meitei scriptures, the Khamnung kingdom is described as a generally dark and cool place, whose capital city is the "Khamnung Sawa", which remains isolated from the rest of the areas, as the "Ashi Turel" ("Ashi Tulel") (Styx river) flows encircling the charmed city of Thongalel. Unless permitted by Thongalel, no souls can enter the "Khamnung Sawa". According to His Will, souls of those who died from suicide are strictly prohibited from entry as a mark of punishment.
