In Jainism, Ajitnatha was the second tirthankara of the present age. According to Jain beliefs, he became a siddha, a liberated soul which has destroyed all of its karma. The soul that became Ajitanatha, in its earlier incarnation, was the great King Vimalvahan of Susima city in Mahavideh area. He led a pious life in spite of the available princely grandeur. At an appropriate time, he became an ascetic under Arindam Suri. Ajitnatha was born to King Jitashatru Raja and Queen Vijaya at Ayodhya in the Ikshvaku clan.
The Yajurveda mentions the name of Ajitanatha, but the meaning is not clear. According to Jain traditions, his younger brother was Sagara. Sagara, who became the second Chakravartin, is known from the traditions of both Hindu and Jain scriptures.
From the Hindu source: Sagara is known to have had many sons. One of them was Bhagiratha, who brought the river Ganges.[which?]
From the Jain source: In his last days, Sagara adopted the life of asceticism from Ajitanatha and retired from the worldly life.
