The Book of the Vishanti contains the most powerful light/order magic spells known, many of them being counterspells to other magic disciplines. It seems to have an endless number of pages, which seemingly materialize from nothing. The book itself can be used to deflect magic. In addition, its spells can never be used for offense, only for defense. The Book is marked with the Seal of the Vishanti. It also contains extensive knowledge introduced by several powerful magicians, such as the information collected by Agamotto regarding his discovery and mastery of the "Three Paths to Enlightenment", and widely detailed information about the Marvel cosmology itself, which was presumably dictated by the Vishanti to the first human authors
