In plain words
Amutaṉār: Once I reached the feet of our Kūrattāzhvāṉ, whose great fame passes beyond all speech and who passed over the pit of the three deceitful prides [of birth, of learning and of conduct], it is no hardship at all for me now to sing of the auspicious qualities of Rāmānuja, who carries sin away, and to escape the ways that do not befit my true nature.
