Sumatinatha was the fifth Jain Tirthankar of the present age (Avasarpini). According to Jain beliefs, he became a siddha, a liberated soul which has destroyed all of its karma.

Sumatinath was born to King Megh Raja and Queen Mangala Rani at Ayodhya in the Ikshvaku clan. His birth date was the eighth day of the Vaishakh shukla month of the Indian calendar.

Vijayasen was the king of Shankhpur town in the Purva Mahavideh area. He had a son named Purushasimha. While he had gone for a walk in the garden one day, the prince listened to the discourse of Acharya Vinayanandan Dev. He became detached and a turned ascetic. As a result of vigorous penance and higher spiritual practices, he earned the Tirthankar-nam-and-gotra-karma. Completing his age, he reincarnated as a god in the Vijayant dimension.

From Vijayant dimension, the soul that was Purushasimha descended into the womb of queen Mangalavati/Sumangala, wife of king Megh of Ayodhya. The news of the queen being pregnant made the atmosphere of Ayodyha live with happiness and joy.
