Rishabhdev (Adinath Bhagwan) ko kai upsarg (upasarg/ashánt) hue the. Sabse pramukh upsarg jo kahaaniyaan mein zyada milta hai, wo hai Diksha lene ke baad anushasan ki raah par nikalne ke baad bhojan ki praapt mein mushkil. Is dauran unhe bahut samay tak sookha bhojan ya sahi bhojan na milna pada, jisse unhe tapasya ki kathin pariksha face karni padi. Isi period mein raja Shreyans ne unhe sahi tarah se bhojan pradan kiya (gane-ras ki gudiya jaisi madhur bhojan-purti). Is upsarg ko Jaina granthon mein “upasarg” ke roop mein varnit kiya gaya hai. aisa maana jaata hai ki yeh pratikriya vipaksha jeevon ki jnana aur ichha ke kaaran hoti hai, par Rishabhdev ne is pareshaani ko dhairya se paar kiya aur aage apne adharm ko tod kar spiritual path par chale.

Aur bhi kuch upasarg ki kahaniyan milti hain jo unke jeevan ke anya parirambhon se judi hui hain, jaise ki upaasanaon aur tapasya ki kathayein, lekin pramukh aur prasiddh upsarg wahi hai jo bhojan ki samasya se juda hua hai. You can read more here
