He was a Telugu Vaidiki Brahmin from Khandrika (Upadrasta) family and a junior contemporary of Emperor Akbar. As a literary theorist or rhetorician, he is renowned for his Rasagaṅgādhara, a work on poetic theory. He was granted the title of Paṇḍitarāja by the Mughal emperor Shah Jahan, at whose court he received patronage.

"Ganga Lahari" is a composition of 52 Sanskrit Shlokas by Jagannath Pandit has historic importance. The Great man was accepted as her spiritual guide by princess Lavangika, Daughter of emperor shah jehan and the prince Dara Shukoh was friendly with him to learn more of Sanskrit and Hindu culture. Both these facts were mistaken by the citizens in Delhias an ordinary earthly love story.
The emperor asked Jagannath Pandit to accept Islam as his religion and marry his daughter which was not acceptable to Jagannath. He started fasting on the banks of river ganga and every day he would compose a shloka to pray the godly and motherly river Ganga.On completion of every shloka the waters rose by a step by step for 52 days (Jeshthha shuddha 1 to 10 are the days called "Ganga Dashahara) in Hindu calendar, and at the end, Pandit Raj offered himself into the river and ended his life nobly.(1670) The band of 52 shlokas is available now also with its meaning and is known as a very beautiful piece of poetry of the old times.
