Sri Purushottama Perumal Temple (Thirunangur)

Along with the ten other Thirunangur shrines, this temple is traditionally held to mark one of the eleven forms Vishnu assumed to pacify Shiva's tandava, but its specific form, Purushottama, carries a distinct theological weight of its own. In Vedantic thought, Purushottama denotes Vishnu as the "Supreme Person" standing above both the perishable material world (kshara) and the individual, imperishable soul (akshara), a philosophical high point among the Thirunangur forms, reinforced here by a temple tank named directly after Vishnu's own cosmic ocean-abode, Thirupaarkadal.

Temple tradition situates this shrine within the same founding legend as its ten Thirunangur neighbours: Shiva's grief-maddened cosmic dance after Sati's death, the celestial deities' alarmed appeal to Vishnu, and Vishnu's calming presence followed by his manifestation in eleven forms at Shiva's own request. Here, that manifestation takes the form of Purushottama, understood by temple tradition as Vishnu's transcendent aspect beyond both matter and individual souls alike, a theological rather than narrative distinction among the eleven.

The temple's three-tiered vimanam over the sanctum, the Sanjeevi Vigraha Vimanam, is named for the Sanjeevi hill of medicinal herbs that Hanuman carried from the Himalayas to revive the wounded Lakshmana during the Ramayana war, a legend of healing and restoration that temple tradition ties to this particular tower's name. The sanctum and its surrounding shrines sit within rectangular enclosing walls, entered through a five-tier Rajagopuram on the east, with the complex laid out in the customary sequence of sanctum sanctorum, antarala, artha mandapam, and mukha mandapam.

This temple shares in the wider Thirunangur cluster's Thirumangai Alvar Mangalasasana Utsavam, held in the Tamil month of Thai (January–February), when all eleven temples' festival deities are brought together on Garuda mounts for a combined celebration.

Daily worship at Thirunangur-cluster temples such as this one customarily follows a four-fold rhythm (an early Ushathkalam, a mid-morning Kalasanthi, an evening Sayarakshai, and a closing Ardha Jamam) though exact timings and the number of daily poojas can vary by temple and should be confirmed locally. Archana at Purushottama Perumal's sanctum is offered beside the Thirupaarkadal Theertham, the tank named for Vishnu's own Ocean of Milk.
