He has written in praise of the Chola King Kulamuttratthu Thunjiya Killi Valavan (Purananuru verse 42).
[citation needed] Verse 54 of the Tiruvalluva Maalai, an encomium written on Valluvar and the Kural literature, is attributed to Idaikaadar.
The verse suggests, "Valluvar pierced a mustard and injected seven seas into it and compressed it into what we have today as Kural.
"[5] He is one of the two contributors of the Tiruvalluva Maalai who have penned the verse in the Kural venba metre, the other one being Avvaiyar.
Such is the ingenuity of its author, that he has compressed within its narrow limits all the branches of knowledge, as if he had hollowed a mustard seed, and enclosed all the waters of the seven seas in it.
