Rishabhanatha
Rishabhanatha ( Sanskrit, lit. "bull lord"), also Ṛṣabhadeva or Rishabhadeva, is said to be the first Tirthankara (Teaching God) of the present half cycle of time. The word Tīrthankara signifies the founder of a tirtha which means a fordable passage across a sea. The Tirthankara show the 'fordable path' across the sea of interminable births and deaths ( saṃsāra). Rishabhanatha is also known as Ādinātha which translates into "First (Adi) Lord (nātha)".
