Puranic scriptures contain occasional references to ansh - literally 'portion, or avatars of Shiva', but the idea of Shiva avatars is not universally accepted in Saivism. The Linga Purana mentions twenty-eight forms of Shiva which are sometimes seen as avatars, however such mention is unusual and the avatars of Shiva is relatively rare in Shaivism compared to the well emphasized concept of Vishnu avatars in Vaishnavism.
