Followers of Ayyavazhi differ from other Hindus in that they recognize a Satan-like figure, Kroni, who is the primordial manifestation of evil and who manifests in various forms, (for example, Ravana and Duryodhana) in different ages or yugas.
Ayyavazhi அய்யாவழி (Tamil: "path of the father"), officially a TamilHindu sect, is a monistic religion that originated in South India in the mid-19th century.
