Thirusengunrur (Iruthai Vinnagaram)

Thirusengunrur, also known as Iruthai Vinnagaram (the Dark Blue Heaven or the Blue Celestial Abode), is a Divya Desam in Tiruvarur district of Tamil Nadu. The presiding deity is Trivikrama Perumal — Vishnu in the cosmic three-stride form — enshrined here on a hill (kunrur = hill town). Thirumangai Alvar celebrated this kshetra in his Periya Thirumozhi, calling it a 'vinnagaram' — a heavenly abode on earth — with the distinctive qualifier 'iruthai' (dark blue, the colour of Vishnu and of deep space), suggesting a place where the divine is palpably present. The Tiruvarur district, dominated by the enormous Tyagaraja Swami complex, is primarily Shaiva in orientation, but contains several Divya Desams attesting to the co-existence of both traditions in this delta region. The Cauvery delta's fertile landscape surrounds this temple.

The name Iruthai Vinnagaram evokes the dark blue sky at night — the colour of Vishnu, of deep water, and of the infinite cosmos. Local tradition holds that when sages performed penance seeking a vision of Vishnu's heaven (Vaikunta), Vishnu manifested at this hill and declared: 'Why journey to Vaikunta when this hill itself is my abode?' The dark blue tint of the gopuram and the sacred tank's water at certain times of day supposedly mirrors the deep blue of cosmic space.
