After the death of his guru, Nanna Sri started undertaking routine wandering to many places alongwith his disciples to preach Jainism. Nanna S ri was a great scholar, expert speaker and gifted. Hence his gaccha made rapid progress. As Nanna S ri was born in a royal family, he was popular as R ja i and his gaccha as R ja gaccha. In this way R ja gaccha in the middle of V.N. 14 h century started shining like the sun during the middle of the day. c ryas of R ja gaccha considered themselves as belonging to Candra gaccha primarily thereby establishing R ja gaccha as a branch of Candra gaccha.
Pradyumana S ri was the disciple of Sahadeva S ri who in turn was the disciple of Ajitaya ov d S ri and who in turn was the disciple of this
c rya Nanna Sri. c rya Pradyumana S ri had from his childhood acquired deep knowledge of Vedas and Ved mgas. While acquiring knowledge of all other religions, he acquired knowledge of Jain philosophy in a comparative manner. In this way he realized that the practice of Jain principles of right belief, right knowledge, right conduct and right penance is the only and right way to achieve complete freedom from the great pains of this world of transmigration, like birth, death, old age, sickness, etc. With such feelings deeply entrenched in his mind, he took initiation in R ja gaccha by its c rya Sahadeva S ri. While serving his guru, he acquired in depth knowledge of Jain scriptures. By acquiring deep knowledge in logic, he became a great debater. He therefore had scriptural discussions with great scholars in the royal courts of Sav laka, Gwalior, Tribhuvanagiri, Cittauda etc. We find mentions in Jain literature that Pradyumanas ri won 84 such debates in his life. By defeating a Digambara crya (in the royal courts of i odiy lineage king Alla a Vikram 922-1010), he made him his disciple.
After c rya Pradyumana S ri, Abhayadeva S ri, who became famous as 'Tarka pamc nana Abhayadevas ri' became the 5th c rya of R ja gaccha. He was also a scholar of very high standard. This Abhayadeva S ri wrote a 25000 verse long kon Sanmati Tarka by crya Siddha Sena which became famous as Mah r ava later. In this text, hundreds of doctrines of Jain and other philosophies are discussed.
By coincidence, this Abhayadeva S ri also belonged to a royal family and so he was also respectfully addressed as R ja i.
