Rishabh Incarnation: Lord Vishnu in his ninth incarnation as Rishabhdev was born to king Nabhi and Marudevi. He was born at Ayodhya in the Ikshvaku clan. He was the first of the 24 Tirthankaras. In Jainism, he is known from many names as such Adinatha, Rishabhanath, Rushabh, Rushabhdev, Adishwar or Kesariyaji. He lived before civilization developed. Because of this, he had the name of Adinath - the original lord.
Lord Rishabh’s mother Marudevi was the daughter of Indra, the leader of the gods. Lord Rishabh was given the title of 'Jin'. His followers are known as Jains. Following the example of lord Rishabhdev many of his subordinate rulers as well as common people got inspired to embrace the ascetic way of life. It is mentioned in scriptures that with Rishabhdev four thousand others also took Diksha.
