In Jainism, "Adinath Bhagwan" refers to Lord Rishabhanatha, the first Tirthankara of the current time cycle (Avasarpini). The term "upsarg" (उपसर्ग) means obstacles, troubles, or afflictions faced by a Tirthankara, often instigated by celestial beings (Devas) or other beings due to jealousy or ignorance.

Adinath Bhagwan (Rishabhanatha) and Upsarg:

According to Jain scriptures, Lord Rishabhanatha faced several upsargs (afflictions) during his lifetime, especially after he renounced the world and became a monk. One of the most notable upsargs he faced was the ordeal of going without food for a long time after taking Diksha (renunciation). Because he was the first Tirthankara and there was no tradition of offering alms to monks, people did not understand how to offer food suitable for monks.

He wandered for a long period (over a year) without receiving suitable food, which was a great upsarg. Ultimately, King Shreyans, due to his past-life knowledge, offered Rishabhanatha sugarcane juice in the correct manner, allowing the Lord to break his fast.

Key Points:

• Adinath Bhagwan faced upsargs mainly in the form of prolonged fasting and lack of proper alms.
• He did not face physical violence or torture like some later Tirthankaras (e.g., Parshvanath or Mahavir Swami), but his upsarg was the severe test of hunger and lack of food.
• This episode is remembered in Jain tradition, and the day is celebrated as "Akshaya Tritiya," marking the first ahar (alms) received by any Jain monk.

Summary: Adinath Bhagwan's primary upsarg was the extended period of not receiving proper food after renunciation, which tested his endurance and set the precedent for Jain monks' alms tradition.
