According to Sri Vaishnava legend, Poigai Alvar once travelled to offer his veneration to Vishnu at the Ulagalantha Perumal temple at Tirukoilur.

During an ensuing rainstorm, Poigai found some accommodation at a mandapam, and was asked by Pey if he could share some space in his room.

The trio decided that it would be most proper for an individual to lie down, two people to be seated, but the fact that there were three of them meant that it would be most suitable for all of them to stand.

[5][6] The first hymn of the Irantam Tiruvantati describes the poet-saint's thoughts when Perumal overwhelmed him with his presence:[7][8] With love as the lamp,passion as the ghee,a mind melting with joyas the wick,with my soul dissolvingI lit the blazing flame of wisdomfor Narayana.I, who desire the wisdom of Tamil.The author also references Vishnu and Lakshmi residing in their celestial abode, Vaikuntha, in this work:[9] The lord of gods in heaven is light-effulgent.

Those who worship his ocean- reclining form, strewing fresh flowers at his feet will be counted as devotees, worthy of entering his fabled celestial city.In that city, under a canopy of pearls, gems and diamonds, and strings of fresh flowers, the lord is seated with the lotus-dame Lakshmi, borne on his right.
