Stotras are Hindu prayers that praise aspects of God, such as Devi, Siva, or Vishnu. Stotras, according to Swami Tapasyananda, are invariably uttered aloud and consist of chanting verses conveying the glory and attributes of God. The three most famous and sacred stotras in Hinduism are Lalitha Sahasranama, Shri Rudram Chamakam, and Vishnu Sahasranama.
