Pārśvanātha , or Pārśva and Pārasanātha, was the 23rd of 24 tīrthaṅkaras ("Ford-Maker" or supreme preacher of Dharma) of Jainism. According to traditional accounts, he was born to King Aśvasena and Queen Vāmādevī of the Ikshvaku dynasty in the north west Indian city of Varanasi in 9th century BCE. Pārśvanātha is the earliest Jaina tīrthaṅkaras who is acknowledged as possibly a historical figure: with some teachings attributed to him that may be accurately recorded, and a possible historical nucleus within the legendary accounts of his life from traditional hagiographies. Historians consider that he may actually have lived between c. 8th to 6th century BCE, founding a proto-Jaina ascetic community which subsequently got revived and reformed by Mahāvīra (6th or 5th century BCE).
According to traditional Jaina sources, Pārśvanātha was born 273 years before Mahāvīra, which places him between the 9th and 8th centuries BCE. Renouncing worldly life, he founded an ascetic community. He was the spiritual successor of the 22nd Tirthankar Neminatha. He is popularly seen as a supreme propagator and reviver of Jainism. Pārśvanātha is said to have attained moksha on Mount Sammeda (Madhuban, Jharkhand) popular as Parasnath hill in the Ganges basin, an important Jaina pilgrimage site. His iconography is notable for the serpent hood over his head, and his worship often includes Dharaṇendra and Padmāvatī (Jainism's serpent Devtā and Devī).
Texts of the two major Jaina sects (Digambaras and Śvētāmbaras) differ on the teachings of Pārśvanath and Mahāvīra, and this is a foundation of the dispute between the two sects. The Digambaras believed that there was no difference between the teachings of Pārśvanātha and Mahāvīra.
Pārśvanath taught that every individual soul possesses infinite knowledge and boundless bliss, but this is obscured by ignorance, causing the soul to identify with the physical body. Through diligent practice of 'bheda-jñāna', which entails right belief and active awareness of one's true nature as a pure soul, unencumbered by the body and its passions, an individual can shed the perception-obscuring mohanīya karma. This enables the soul to experience its true essence, known as samyak darshan or self-realization, opening the pathway to liberation from the cycle of birth and rebirth. According to the Śvētāmbaras, Mahāvīra expanded Pārśvanātha's first four restraints with his ideas on ahimsa (lit. 'non-violence') and added the fifth monastic vow (celibacy). Pārśvanātha did not require celibacy and allowed monks to wear simple outer garments. Śvētāmbara texts, such as section 2.15 of the Ācārāṅga Sūtra, say that Mahāvīra's parents were followers of Pārśvanātha (linking Mahāvīra to a preexisting theology as a reformer of Jaina mendicant tradition).
