Shloka 1:

kshoNI koNa shatAmshapAlanakalA durvAra garvAnala
kshubhyat kshudra narendra chAtu rachanA dhanyAn na manyAmahe |
devam sevitumeva nischinumahe yosau dayAlu: purA
dhAnAmuShTimuche kuchelamunaye dattesma vitteshatAm ||

Meaning:
We do not even bother (na manyAmahe) with those who consider themselves fortunate (dhanyAn) for having praised (chAtu rachanA) the petty lords (kshudra narendra) who protect (pAlana kalA) one portion (shata amsha) of this world's land (kshoNI koNa) whose minds are confused (kshubhyan) with pride which is like fire (garva anala). We are determined (nischinumahe) to only worship (sevitum eva) that (ya: asau) merciful Lord (dayALu: devam) who once (purA) gave (datte sma) Kuchela Muni (kuchela munaye) Kubera's wealth (vitteshatAm) in exchange for one fistful of rice (dhAnA muShTi muche).

Here, Desikan is stating that not only we look to Sriyapathi for giving us Moksha, but even for things of this world we don't go to anyone else. This is a valuable lesson to people who worship anya devatas but say that they do so because it is ok to seek them for material things (after all, one does not go to a king and ask for one rupee - so the argument goes). It is indeed true that we do not go to the supreme Lord who can give the greatest benefit and ask for simple things. And that's not what Desikan is saying. What is being said is, for things big or small, we don't seek anyone else; we only worship Sriman Narayana. We leave it to Him to give us what He wishes.

The kings spoken here are not just the human kings and the world is not just this world. It also applies to anya devatas who are like small kings and who have been given small portions of this universe or small activities to rule over.

Here we can think of Azhvar's words:
unakkup paNi seydhirukkum thavam udaiyEn inippOy oruvan
thanakkup paNindhu kadaiththalai niRkai ninsAyai azhivu kaNdAy
Periyazhvar Thirumozhi 5-3-3

Azhvar's thiruvuLLam is fully reflected by Vedanta Desikan.
