In Meitei mythology (Manipuri mythology), death is personified with multiple deities, including Thongalel, the ruler of the underworld and the god of the death, along with his wives.

At these tasks, he is assisted by Thongak Lairembi and Khamnung Kikoi Louonbi. The underworld kingdom is called "Khamnung kingdom" and its capital city, "Khamnung Sawa" is in the middle of the river "Ashi Turel", which has only a single bridge made up of a thread. This should be crossed over by only those souls who do not commit suicide during their earthly life.
