He is the first Viharman Tirthankar.  He was born in the Pundarikini town of the Pushpakalavati State of the east Mahavideh area in the Jambu continent.  His father was king Shreyans and mother Satyaki.  He was considered to be a greatmen as his mother had seen the fourteen great dreams.  His symbol is bull.  He was given the name Simandhar because he followed the discipline to highest limit.

When be became young his body grew to 500 Dhanush in height and he was married to a princess named Rukmani.

After an age of 8.3 million Purvas he became an ascetic and attained omniscience.  His complete age is 8.4 million Purvas.

The twenty Viharman Tirthankars existing at present in the Mahavideh area were born at the same time just after the Nirvana of the 17^th Tirthankar of Bharat area, Kunthunath.  All of them took Diksha together just after the Nirvana of 20t^h Tirthankar Munisuvrat.  Just after one month of becoming ascetics they all attained omniscience.  They all will get liberated at the same time after the Nirvana of the seventh Tirthankar of future ascending cycle of time, Shri Udaynath.

When all these Tirthankars are liberated other future Tirthankars will attain omniscience in the other part of Mahavideh area.  This is an unbroken tradition since time immemorial and will continue for all the time to time.  The rule is that a minimum of twenty Tirthankars must always exist.  The maximum number can go upto 170.
