Summary: unique to Indian architecture, consisting of a curvilinear spire with several tiers or stories, representing the cosmic mountain or Meru, the abode of the gods. The sikhara symbolizes the upward ascent of the soul towards God, and the temple as a whole represents the universe, with the sanctum at the center. The vimana, or shrine, is like a cosmic chariot carrying the deity, and the nagara style of temple architecture developed with the sikhara as its crowning glory. Thus, the sikhara became an integral part of the Hindu temple architecture, reflecting the spiritual and cosmological beliefs of the Aryan civilization that influenced Indian art and temple design.
