From the Nammazhvar Tiruvadi Thozhal celebration which is based on the Thiruvaimozhi’ s last two decads, it is clear how a soul reaches Emperuman. What is the reason for a similar Tirvadi Thozhal function that is conducted for Thirumangaiyazhvar?

Thirumangaiyazhvar’s Tiruvadi Thozhal is conducted with a similar intent to that of Nammazhvar Tiruvadi Thozhal – that is, it celebrates the glorious occasion when Azhvar reached the eternal abode, Paramapadam.
Thirumangaiyazhvar Tiruvadi Thozal can generally be witnessed at a select few Divya Desam-s in the south. Particularly, we can witness this at Tirukkudantai. At Tirukkudantai, after the conclusion of Azhvar Tiruvadi Thozhal, the devotees get to view a scenario where Azvhar performs Tiruvaradhanam for Emperuman. This is conducted after the recitation of “mATRamuLa” decad which is followed by Azhvar Tiruvadi Thozal, recitation of Tirukkurntandakam and Tiruneduntandakam. But at other temples, this order is different – Azhvar Tiruvadi Thozal is after Tiruneduntandakam. This is because the satrumurai pasuram of Tiruneduntandakam concludes “tankuDantai kiDanda mAlai neDyAnai aDinAyEn ninaindittEnE”;
In both, the intent and feel are the same. We celebrate the occasion when both the Azhvars reached Paramapadam. It appears that at Tirkkudantai, Thirumazhisaippiran Tiruvadi Thozhal takes place. All these Utsavam-s are for the devotees to celebrate Azhvars’ attaining Paramapadam.
