Rushabhdev, also known as Rishabhanatha or Adinath, is regarded in Jainism as the first Tirthankar—the first enlightened teacher who established the path to liberation for all beings in this cosmic age.

A simple, traditional outline of his story:

• Birth and royal life: Rushabhdev is said to have been born in a royal family to King Nabhi and Queen Marudevi. He grew up as a prince and learned all the skills required of a king.
• Renunciation: After many years of ruling, he chose the path of renunciation, leaving behind royal pleasures to seek spiritual truth and liberation.
• Spiritual awakening and teaching: In deep meditation and through right conduct, he attained kevala jnana (omniscient knowledge) and began teaching others the dharma—non-violence, truth, celibacy, and ethical living as the means to liberation.
• Role in Jain tradition: He established the early Jain community and laid down the ideals and practices that later Tirthankaras would follow. His life set a pattern of renunciation, discipline, and compassion that is central to Jain ethics.
• Legacy: His son Bharata Chakravarti is often cited in Jain texts as a mighty king who ruled with righteousness, illustrating the harmony between worldly duty and spiritual aspiration that Rushabhdev exemplified.
• Path to moksha: Like other Tirthankaras, Rushabhdev ultimately achieved moksha (liberation) and is revered as a perfected soul who guides others toward the same goal.

Notes:

• There are small differences in details between Digambara and Śvetāmbara traditions about names, dates, and some events, but the core message remains the same: Rushabhdev is the first teacher who shows the path to liberation.
