Sri Vaishnava acharya Manava Mamunigal (also known as Varavara muni or Manavala Mahamunigal.) is always depicted to have covered with hoods of snake. The snake is Adi Shesha.
There are many idols and utsava murtis in Divya deshams which show him covered completely with Adi Shesha.
Above is the Utsavar (processional deity) of Manavala Mamunigal at Tiruvelukkai, one of Divyadeshams.
Why is Manavala Mahamunigal covered by a hood of Adi Shesha? What does this represent? Is there any story explaining his relation with Adi Shesha?
