Vishnu Purana
The Vishnu Purana presents Vishnu as the central element of its cosmology, unlike some other Puranas where Shiva or Brahma or goddess Shakti are. The reverence and the worship of Vishnu is described in 22 chapters of the first part of Vishnu Purana, along with the profuse use of the synonymous names of Vishnu such as Hari, Janardana, Madhava, Achyuta, Hrishikesha and others.
