The nama-stotra is based on chanting a litany of names for a deity. The Sahasranama, a type of nama-stotra, is a litany of a thousand names for a particular deity. Sahasranama means 1000 names; Sahasra means 1000 and nama means names. For example, Vishnu Sahasranama means 1000 names of Vishnu. Other nama-stotras may include 100 or 108 epithets of the deity. According to Hinduism, the names of God are valuable tools for devotion.
