Jainism ke anusar, jivo ki sankhya batane wale Jineshwar Bhagwan Rishabhdev (Aadinath) hain. Rishabhdev Bhagwan, jo pehle Tirthankar hain, unhone hi sabse pehle shrishti me jivon ki vibhinn yoni, unki sankhya, aur unke gun-dharmon ka varnan kiya tha. Unhone hi "Jiv Vichar" ka vistar se prachar kiya tha.

Is prakar, Bhagwan Rishabhdev ko hi jivo ki sankhya batane wale Jineshwar mana jata hai.
