Rishabhanatha also known as Ṛṣabhadeva, Rishabhadeva, or Ṛṣabha (which literally means "bull") is the first Tirthankara (ford maker) in Jainism. A mythical leader, he is believed in Jainism to have lived millions of years ago. He was the first of twenty four teachers in the present half cycle of time in Jain cosmology, and called a ford maker because his teachings helped one across the sea of interminable rebirths and deaths (saṃsāra). He is also known as Ādinātha of Jainism which translates into "First (Adi) Lord (nātha)", as well as Adishvara (first ishvara), Yugadideva (deva of yuga), Prathamaraja (first king), and Nebheya (son of Nabhi). Along with Mahavira, Parshvanatha and Neminatha, Rishabhanatha is one of the four Tirthankaras that attract the most devotional worship among the Jains.
According to Jain texts, Rishabhanatha was born in a king's family in the age when there was happiness all around with no one needing to do any work because of Kalpavriksha (miraculous wish-fulfilling trees). Gradually as the cycle progressed, the efficacy of these trees decreased, people rushed to their king for help.
Rishabhanatha is then said to have taught the men six main professions. These were:
(1) Asi (swordsmanship for protection),
(2) Masi (writing skills),
(3) Krishi (agriculture),
(4) Vidya (knowledge),
(5) Vanijya (trade and commerce) and
(6) Shilp (crafts)
Rishabhanatha was born to King Nabhi and Queen Marudevi in Ayodhya, on the ninth day of the dark half of the month of Chaitra-caitra krişna navamĩ. This is the second auspicious event and is known as Janma Kalyanaka. The association of Rishabhanatha to Ayodhya makes it a sacred town for Jains, as it is in Hinduism for the birth of mythical god Rama.
Marriage and children :
Rishabhanatha had two wives, Sunanda and Sumangala. Sumangala was the mother of ninety-nine sons (including Bharata) and one daughter, Brahmi. Sunanda was the mother of Bahubali and Sundari
