The latter were either taken to represent the multiple facets of the same god or else were supposed to denote different forms and appellations by which the god came to be known and worshipped. [...] Siva became identified with countless local cults by the sheer suffixing of Isa or Isvara to the name of the local deity, e.g., Bhutesvara, Hatakesvara, Chandesvara.
