Among Sinhalese Buddhists, Maha Sona or Maha Sohona — Mahasona in many English spellings — is one of the most widely feared yakkas, a demon of the cemetery whose name can be heard as the great sohon, the great grave. He is said to haunt graveyards, hills, and junctions where three roads meet. Accounts describe him killing by crushing the shoulders or by sending illness, leaving a hand-mark, and moving at dusk against people who walk alone. Kattadiya are called when affliction is attributed to him. He belongs to a cosmos in which demons, gods, and planetary powers share the work of explaining misfortune.

A well-known origin legend remembers him as Ritigala Jayasena, a giant warrior of King Dutugemunu's time, decapitated in a duel with Gotaimbara. In the hurry to restore him before the body cooled, a deity fixed a bear's head, and he rose as Mahasona. A. A. Perera's Sinhalese Folklore Notes already describes Maha Sohona as bear-headed, presiding over graveyards and three roads, inflicting cholera and dysentery. That is one strand. Ritual practice is another: he is a named agent in healing, not only a story-giant.

Bruce Kapferer's ethnography of Sinhalese demon ceremonies around Galle takes the Mahasona samayama as a central rite: all-night dance, music, and cosmic drama through which a patient's disorder is staged and turned. In that setting Mahasona is not a cryptid to be photographed. He is a being whose terror is made visible so that it can be commanded, mocked, and sent back. Decay, death, and hunger are the qualities the rite handles.

This archive files Mahasona as Sinhalese night-visitor and cemetery yakka, not a generic South Asian ghoul. Related names such as Riri Yaka belong to the same ritual map and should not be collapsed into him. The bear head is a remembered sign, not a zoo exhibit. Prefer Sinhalese and scholarly accounts of the rite over tourist horror. The dead ground is his, and the living still know how to call specialists when the cemetery will not stay at the cemetery.
