Dashavatara refers to the ten principal avatars. In Vaishnava philosophy, an avatar most commonly refers to the 'descent' and daśa refers to 'ten' in number. The ten most famous incarnations of Vishnu or sometimes Krishna are collectively known as the Dashavatara. This list is included in the Garuda Purana (1.86.10-11) and denotes those avatars most prominent in terms of their influence on human society.
