Aranath(Arnath) was the eighteenth Jain Tirthankar of the present half cycle of time (Avasarpini). He was also the eighth Chakravartin and thirteenth Kamadeva. According to Jain beliefs, he was born around 16,585,000 BCE. He became a siddha i.e. a liberated soul which has destroyed all of its karmas. Aranath was born to King Sudarshana and Queen Devi (Mitra) at Hastinapur in the Ikshvaku dynasty. His birth date was the tenth day of the Migsar Krishna month of the Indian calendar.

In Jainism, a Tirthankara is a saviour and supreme spiritual teacher of the dharma. The word tirthankara signifies the founder of a tirtha, a fordable passage across saṃsāra, the sea of interminable birth and death. According to Jains, tirthankaras are the supreme preachers of dharma, who have conquered saṃsāra on their own and made a path for others to follow. After understanding the true nature of the self or soul, the Tīrthaṅkara attains kevala jnana (omniscience). A Tirthankara provides a bridge for others to follow them from saṃsāra to moksha (liberation).
