One Supreme Being
Some western scholars in their ignorance have dubbed Hindu religion as polytheistic. The uniqueness of our religion lies in the fact that under whichever name a devotee worships his Ishtadevata-that manifestation of God which appeals to him most-he considers Him as all-pervading Paramatama. In fact, the culmination of all conceptions of the Supreme Being is in Monism. That is Advaita Vedanta. Isvara, Narayana and Parasakti are all different aspects of the one Supreme Being. This is visibly illustrated in the divine forms of Ardhanareeswara and Sankara-Narayana. Such manifestations of the Divine are installed in many South Indian temples, such as Ardhanareeswara at Triuchengode, Sankaranarayana at sankaranarayana Koil in Triunelveli, and Harihara in Mysore. Siva and Vishnu are also found together in the temple at Tiruparkadal near Kaveripakkam.
