The name of the powerful and illustrious king of Khadgi town in Purva Mahavideh area was Simhavaha.  He was a very devoted and religious person.  When his son became young and capable, he handed over his kingdom to the son and took Diksha from Samvaracharya.  As a result of his vigorous penance and devotion for the Arhat, he earned the Tirthankar-nam-and-gotra-karma.  Completing his age he reincarnated in the Sarvarthasiddha dimension of gods.

From the dimension of gods he descended into the womb of Queen Shri Devi, wife of king Shursen of Hastinapur.  During her pregnancy the queen saw a heap of gemstones known as Kunthu in her dreams.  This inspired the king to name him Kunthu Kumar.  The pious deeds of earlier birth resulted in unlimited power and grandeur for Kunthu Kumar.  After Shursen became an ascetic, Kunthu Kumar ascended the throne.  Soon the disc weapon appeared in his armoury and he proceeded to conquer the world with his mighty army.  Without any confrontation all the kings accepted his sovereignty and Kunthunath became a Chakravarti.  Many mighty kings and princes used to be present in his court all the time.  After a long and peaceful reign of twenty three thousand seven hundred and fifty years he became an ascetic alongwith one thousand kings.  Immediately after Diksha he acquired Manahparyava Jnan.  He spent sixteen years as an ordinary ascetic.  Indulging in penances and other spiritual practices, he attained omniscience on the third day of the bright half of the month of Chaitra under a Tilak tree in the Sahasramra jungle outside Hastinapur.  His first discourse was on the subject of "inner purity".

As an omniscient ascetic Kunthunath wandered around and preached true religion for a very long period.  He then went to Sammetshikhar and observed a month long fast before breathing his last.  His followers were deeply devoted to him.  As such, a large crowd was present at the moment of his Nirvana and cremation ceremony.  They witnessed the ceremony with heavy hearts and tear filled eyes.  The mortal remains of Bhagavan Kunthunath were taken away by the gods for worship.
