You are really delving into it, aren't you? Just the thing to do! Without bhakthas' imagination, their million ways of seeing divinity and reveling in the joy of it, music would have remained in the form of just notes (like bird song), swaras and tanam. I am letting my imagination take command here. Anyway, something to that effect.
AnDAL's words: tingaLum Adityanum ezhundARpOL
angaNiraNDum koNDengaL mEl nOkkudiyEl
As though the moon and sun have risen,
with those eyes glance at us!
As you say, moon like (soothing) to bhakthAs, and as the sun (burning) when it comes to evil doers. We may go on to say, the conch for the moon and discus for the sun and so on, until cmlover puts us in our places
