Jain dharma ke anusar, Rishabh Bhagwan ke pita ka naam Nabhiraj (ya Nabhi Raja) tha. Jab Nabhiraj ka samavasaran mein updesh sunne ke baad moksha prapti ka samay aaya, tab unhone apni antim saans tyaag kar ke swarg gati prapt ki. Jain granthon ke anusar, Nabhiraj dev gati mein janm lete hain, aur unka dev naam 'Sarvarthasiddhi' hota hai.

Unki jati ki baat karein, to Nabhiraj Ikshvaku vansh ke Raja the, jo kshatriya jati se sambandhit tha. Lekin swarg me janm lene ke baad, jati ka sambandh nahi rehta; ve dev gati ke dev ban jate hain.

Is prakar, Rishabh Bhagwan ke pita Nabhiraj dev gati mein janm lekar 'Sarvarthasiddhi' dev bane.
