Aadinath Bhagwan, jinhen Rishabhdev bhi kaha jata hai, Jain dharm ke pratham Tirthankar hain. Jain granthon ke anusar, ve is samay ke chhati (अवसर्पिणी) kaal ke pratham Tirthankar the. Avsarpini aur Utsarpini, ye do samay-chakra (time cycles) Jain darshan mein varnit hain.

Aadinath Bhagwan ka janm Ikshvaku vansh mein, Bharat kshetra ke Ayodhya nagar mein hua tha. Unka janm bahut prachin samay mein mana jata hai, jo ki is avasarpini kaal ke pratham yug mein tha. Jain dharm ke anusar, unka janm lagbhag crodon varsh pehle hua tha, jo ki manushya ki samanya kalpana se bahut purana hai.

Is prakar, Aadinath Bhagwan ka janm avsarpini kaal ke pratham yug mein hua tha.
