I seriously doubt this. There is a lot of difference between the bhakthi in
tyaagaraaja kRtis and that of other admittedly madhura bhakti poets.
tyaagaraaja's bhakti is more philosophical. Initially, it is said,
tyaagaraaja was very fascinated by 'advaitam', but later on, he matured
even beyond that, to the level of pure bhakti. My opinions only.
