Story Of Origin Of Adat Vishnu Temple
It is said that Kurooramma used to worship Guruvayoorappan in the spot where the current Adat Vishnu temple is located. An unknown boy used to appear during the puja time and help Kurooramma with the puja.
Once Kurooramma prepared naivedya for the puja and was waiting for the arrival of Vilwamangalam Swamiyar to perform the puja. But soon Kurooramma noticed that the boy who had come to help had eaten all the naivedya.
When the boy realized that Kurooramma had seen him eating naivedya he hid inside a big pot. Kurooramma closed the pot with a lid.
When Vilwamangalam Swamiyar came for puja, she narrated the incident and opened the pot to show the naughty boy. But the boy was not to be seen.
Vilwamangalam Swamiyar and Kurooramma then realized that the boy was Guruvayoorappan. Adat here refers to closed – the pot being closed.
