Chapter 134 of Anushasana Parva recites Vishnu sahasranama - a list of 1,000 names (sahasranama) of Vishnu. Included in the list of 1000 names for Vishnu are Shiva, Sharva, Sthanu, Ishana and Rudra. This synonymous listing of Shiva and Vishnu as one, in Mahabharata, has led to the belief that all gods mentioned in Vedic literature are one.
