In Hindu mythology, Kabandha (, , lit. "headless torso") is a Rakshasa (demon) who is killed and freed from a curse by the god Rama – an Avatar of Vishnu – and his brother Lakshmana. Kabandha's legend appears in the Hindu epics Ramayana and Mahabharata, as well as in later Ramayana adaptations.
Kabandha was a gandharva (celestial musician) named Vishvavasu or Danu, who was cursed and made into an ugly, carnivorous demon by Indra, the king of the gods, and/or a sage. In an encounter with Rama and Lakshmana, the brothers sever his arms and proceed to cremate his corpse. Upon his death, Kabandha resumes his gandharva form and directs Rama to the Rsyamukha mountain, where the exiled monkey-chief Sugriva is hiding. Kabandha advises Rama to form an alliance with Sugriva, who would be of assistance in the search for Rama's wife Sita, who had been kidnapped by Ravana, the demon-king of Lanka. Following Kabandha's instructions, Rama befriends Sugriva and rescues Sita with his help.
