King Dhanpati of Susima City in Mahavideh area took Diksha from Samvar Muni and after acquiring Tirthankar-nam-and-gotra-karma he reincarnated in the Graiveyak dimension of gods.  From there he descended into the womb of Queen Maha Devi, wife of king Sudarshan of Hastinapur.  Besides the fourteen great dreams that precede the conception of a Tirthankar, queen Maha Devi also saw a gem studded wheel (Ara).  Accordingly, after the birth the boy was named Ara Kumar.

When Ara Kumar became young he was married to many beautiful princesses.  Later king Sudarshan gave the kingdom to Ara Kumar and became an ascetic.  For some years Arnath ruled as a regional king.  Gradually his power and glory increased and one-day the disc weapon appeared in his armoury.  He conquered the six continents and became a Chakravarti.  In his attendance were thirty two thousand kings.

After a long and successful reign, one day Emperor Arnath was thinking about the ever changing seasons.  This triggered a chain of sublime thoughts that lead to complete detachment.  He renunciated all the wealth, power and glory and became an ascetic.  He did spiritual practices and wandered around.  After three years he arrived in the Sahasramra jungle outside Hastinapur and stood in meditation under a mango tree.  With the fire of higher meditation he burnt one after another the four vitiating Karmas including illusory, knowledge obstructing, perception obstructing, and power hindering.  Consequently he attained omniscience.  His first discourse after attaining omniscience was on the subject of "how to win over the enemies like attachment and aversion". 

In this first religious assembly thousands of individuals became ascetics including his 32 chief disciples headed by Kumbh.  Spending a long period of twenty one thousand years wandering and promoting religion, he finally arrived at Sammetshikhar and attained liberation.

The sixth and seventh Vasudevas and Baldevas and the eighth Chakravarti (Subhum) were his followers.
