Sri Jayadeva

In a place called Tindubilva, a brahmin couple lived near the temple of jaganath, since they were childless they used to pray for a child. By the grace of the Lord they got a son whom they named him as Jayadeva. They were very happy to have a child and were enjoying all the pranks and movement of the child. During his eighth year they performed "Upanayanam" for their son. Their love for their son was so intense that they didn't send to school because they thought that it would tire him. So Jayadeva used to play freely and spend his time with the friends. But Jayadeva happened to be a sharp and intelligent boy, so though he didnt go to any school, he was able to to learn and study just by listening to his friends studying. He was able to grasp everything just by listening. Hence by the time he attained sixteen years he became a great scholar
Even pundits who happened to have formal education and training were of no match to Jayadeva. The great pundits and scholars were completely dumb struck by the thoughts of Jayadeva, that they thought he was an incarnation of Sage Vyasa. Jayadeva gave importance to service to God or Lord, so he used to sing bhajans and used to compose a lot of songs on the Lord. Because all his composition came front the heart, people liked it instantly. His most popular composition was "Gita govinda". He married a pious lady by name Padmavathi, she was also a devotee of the Lord. He also sang the twenty four astapadis , these astapadis and Gita govinda are still sung by many devotees of Lord Krishna and enjoyed by everyone. Jayadeva along with his wife reached the feet of the Lord in the end.
