Visitors to the temple can get to worship Lord Ranganatha at close quarters in the innermost sanctum.
He rests in a reclining pose on Adisesha, the coiled serpent with five hoods. A unique feature of his idol is that it is crafted using stucco and thailam, a paste made of musk, camphor, honey, jaggery and sandal.
His sanctum is adorned with a gold-plated vimanam or crown tower and shaped like the term Om in Tamil. Its gable features Paravasudeva or the Supreme Being as well as an etching of Ramanuja, the 11th century religious scholar.
Devotees can also expect to get a darshan of other deities at each of the 81 shrines within the temple complex. These include various forms of Lord Vishnu and Goddess Lakshmi as well as religious scholars and Alwar or Bhakthi poet saints.
These include Chakkarathazhwar, Narasimha, Rama, Hayagreeva, Gopala Krishna, Sridevi, Bhudevi and Alagiyamanavalan.
