Aadinath, also called Rishabhdev or Rishabhanatha, is the first Tirthankar in Jainism.

He is respected as the pioneer who showed the path of dharma, discipline, non-violence, and spiritual upliftment to humanity. In Jain tradition, he is regarded as the founder of organized life and righteous conduct in this era.

In simple words:

• Aadinath = First Tirthankar
• Also known as Rishabhdev
• Revered for teaching the path of Ahimsa, truth, and detachment

If you want, I can also explain his life story or his importance in Jain scriptures.
