Sthalapurana of Srirangam — The Cosmic Island of Raṅganātha
The Gift of Vibhīṣaṇa
In the Tretā Yuga, after the great war of the Rāmāyaṇa, Rāvaṇa's virtuous brother Vibhīṣaṇa was crowned king of Laṅkā. Though a demon by birth, Vibhīṣaṇa was a devout bhakta of Lord Viṣṇu. As a blessing for his righteousness, Lord Rāma gifted Vibhīṣaṇa a sacred Ranga-vimāna — a divine conch-shaped icon of Viṣṇu reclining on Ādiśeṣa, which Rāma himself had worshipped.
Vibhīṣaṇa carried the vimāna upon his head and began the journey south to Laṅkā. But the gods had other plans. As he rested on the banks of the Kaverī, a young boy appeared before him. "Set down the Lord for a moment," the boy said, "and I will show you the perfect place to install Him."
Vibhīṣaṇa, exhausted, placed the vimāna upon the ground. Instantly, the boy vanished — he was none other than Gaṇeśa, sent by the gods to ensure the Lord would never leave this blessed land. For once set down, the vimāna could not be lifted again. Try as he might, Vibhīṣaṇa could not move it even an inch.
The River as a Moat
Heartbroken but understanding divine will, Vibhīṣaṇa begged the Lord to at least face south, toward Laṅkā, so he could see Him from his island kingdom. Raṅganātha granted this boon — His feet point south, toward Laṅkā, blessing Vibhīṣaṇa eternally.
To protect this sacred site, the Kaverī river itself changed course, encircling the temple in seven concentric rings — the seven prakārams that make Srirangam the largest functioning temple complex in the world. Each prakāram represents a layer of the cosmic fortress, with the innermost sanctum at the very center of the universe.
The Āḻvār Connection
In the Kali Yuga, the 12 Āḻvār saints rediscovered this site through their hymns. Kulaśekhara Āḻvār (9th c.) declared Srirangam the foremost of all Divya Desams. Tirumaṅgai Āḻvār described the Lord's beauty in ecstatic verses. Āṇḍāḷ, the only female Āḻvār, composed her entire Tiruppāvai as a love-song to this very Raṅganātha.
Pilgrimage and Liberation
Devotees believe that circumambulating all seven prakārams — a walk of several kilometers — grants the same merit as circumambulating the entire cosmos. Dying within the temple's walls, or even being cremated with soil from its grounds, ensures mokṣa (liberation). The temple's south-facing deity, unique among Vishnu temples, reminds all who enter: even the most unlikely devotee — a demon king from Laṅkā — can earn the Lord's eternal grace.
