Swami,
Has devareer heard the discussion between Azhwaan and Udayavar?
After Azhwan received permission from Periya Perumal to leave his body, Udayavar was shocked and said, he said leave before Azhwan. Azhwan said that’s not right. There is a tradition in Sri Vaikuntam that residents welcome the newcomers by washing their feet. Even there Azhwan wanted to perform kaimkariyam to Udayavar and not vice versa. Such great personality emperumAnAr himself proclaims that it was due to his connection to kUrathAzhwAn he gets mOksham.
There are other instances that adiyen is trying to recollect and will share as adiyen remembers them.
Hope this helps.
adiyen,
Badrinarayana Ramanuja Dasan.
