Dear Swamy/Periyava,
Adiyen ramanujadasan
When adiyen looked at the Mukthinath perumal this doubt came ! Sometimes perumal vigraha telling about that location speciality and regional differences and looks ?. Like this is there any research or praise or pointer about that regional perumal looks and regional people culture?.
Mukthinath temple tells about Nepal culture and people face looks?. If so every DD needs to be read for the geographical reference than the history books.
Adiyen ramanujadasan.
