Sutra:
22. maRRellAm pEsilum engiRapadiyE aRiyavENdum arththamellAm ithukkuLLE uNdu.

Meaning:
As in Thirumangai Azhvar's pAsuram "nin thiruvettezhuththum kaRRu maRRellAm pEsilum", this Thirumanthra has in it, all the meanings that are required for the upliftment of the soul.

Sri PBA Swami's Sarartha Deepikai:
The Thirumanthra is now being celebrated as one that contains all the meanings that one needs.

Thirumangai Azhvar sang, "maRRumOr theyvam uLathenRiruppArOdu uRRilEn uRRathum unnadiyArkkadimai, maRRellAm pEsilum nin thiruvettezhuththum kaRRu nAn thirukkaNNapurathtuRai ammAnE".

Its meaning is: O Lord of Thirukkannapuram! I will not be with those who consider attachment to gods other than You. Your divine ashtakshara manthra has in it all the meanings that one has to learn. Yet I will not consider all those meanings and instead consider that the only meaning of the Thirumanthra is bhAgavata kainkarya and learn that alone.

Here, by the phrase "maRRellAm pEsilum" it is clear that the Thirumanthra has in it all the meanings that are necessary for the upliftment of the soul to His lotus feet.
