Ranganatha (Srirangam)

Ranganatha is the presiding deity of the Srirangam Temple in Tamil Nadu, the largest functioning temple complex in the world. This form of Vishnu is depicted reclining on the serpent Adishesha in yoga nidra (cosmic sleep), symbolizing the state of supreme consciousness that sustains the universe. The iconography shows four arms: one supports the head, while the others hold the shankha (conch), chakra (discus), and gada (mace). Lakshmi (Ranganayaki) is seated at his feet, and Brahma emerges from a lotus arising from his navel, signifying the cycle of creation.

According to the Brahmanda Purana, the deity was originally worshipped by Brahma on the banks of the Ksheera Sagara (ocean of milk) and later brought to earth by King Vibhishana, who was stopped at Srirangam by the sage Gautama, where the deity chose to remain. The temple complex is enclosed by seven concentric walls (prakarams), representing the seven layers of the cosmos. Ranganatha is the central deity of Sri Vaishnavism, and the temple is the foremost of the 108 Divya Desams, as celebrated in the Divya Prabandham, the Tamil hymns of the Alvars. The Alvars, particularly Nammalvar and Tirumangai Alvar, composed numerous verses extolling Ranganatha's grace.

The deity's posture of reclining on Adishesha represents the cosmic rest between cycles of creation, as described in the Bhagavata Purana (10.14.22), where Vishnu's yoga nidra is the source of all manifestation. Regional worship traditions include elaborate rituals such as the daily pujas, the grand Vaikuntha Ekadashi festival when the sanctum's inner door is opened, and the Ratha Saptami procession. The temple's history is deeply intertwined with the Sri Vaishnava acharyas, including Ramanuja, who established the temple's worship practices. Ranganatha's role in Hindu cosmology is that of the supreme lord who maintains the universe while remaining in a state of transcendental repose, embodying the paradox of dynamic stillness.

The deity is also known as Srirangam Perumal or Araṅgar in Tamil. The Mahabharata (Vana Parva) references the sacredness of the Kaveri river, on whose banks the temple stands, further sanctifying the site.
