வரும்படி சொலிலைவந்தென் படியளவருந்திடென் நல்விதி யருணாசலா
வரும்படி சொலிலை வந்து என் படியளவு அருந்திட என் நல்விதி அருணாசலா
In plain words
You never invited me. Let us be accurate: no invitation was ever sent. You came, and you ate what there was — all of it, exactly to the measure. And that, as it turns out, is the luckiest thing that ever happened to me.
Word for word
You did not bid me come. You came, and consumed me to the full measure of my portion — that is my good fortune. O Arunachala!
