Tamil roots of sanskrit words

[rajraj]

Mala: I have the two volumes of Thyagaraja's compositions by Rangaramanuja Ayyangar and also the one by Parthasarathi.
The song you are referring to is
'maanasa sancharare raame
varamuni bhaktha loka.......' is in PunnaagavaraLi. Not a very popular composition. When people say 'maanasa sancharare' it is usually the composition by Sadasiva Brahmendrar. It goes like:

maanasa sancharare brahmaNi maanasa sancharare
sri ramNi kucha dhurga vihaare.......

The confusion is due to the popularity of the Sadasive Brahmendrar composition in Shyaama.
