'The Śiva Sahasranāma Stotra is a hymn recounting the 1008 names of Lord Shiva. All of the 1008 names of Lord Shiva can be found in the Śiva Purana – Kotirudra Samhita (Book IV – Chapter 35, 1-133) and in the Book 13 (Anushasana Parva) of the Mahabharata. According to the Ahirbudhanya Samhita, "Vishnu, in the form of Chakra, was held as the ideal of worship for kings desirous of obtaining universal sovereignty", a concept associated with the Bhagavata cult in the Puranas, a religious condition traceable to the Gupta period, which also led to the Chakravartin concept. The concept of universal sovereignty possibly facilitated the syncretism of Krishna and Vishnu and reciprocally reinforced their military power and heroic exploits; with the kshatriya hero, Krishna preserving order in the phenomenal world while the composite Vishnu is the creator and upholder of the universe supporting all existence. Chakra Perumal is the personified deification of Vishnu's Sudarshana Chakra.'
