In Jain tradition, Arhat Muni—though already liberated—leads other monks in observing Chaturmas (the four-month rainy-season retreat). The focus is staying in one place, practicing intensified austerities, study, and teaching, and traveling less during this period.

Key points about the location:

• Chaturmas is observed by Jain monks in a fixed place for the entire four months, chosen each year based on suitability (temple towns, villages with sangh support, or suitable hermitages).
• It is not a fixed national location; different years can see the retreat held in different towns or regions, depending on where a sangh can gather and sustain the monastic group.
• The four-month stay usually occurs during the monsoon season, roughly aligning with the rainy period in the Indian calendar, and ends with prayers and processions marking the end of Chaturmas.

Differences between Digambar and Shwetambar:

• Both traditions observe Chaturmas, but the practical arrangements (where exactly the retreat happens, lengths of specific observances, and scripts followed) can vary by lineage and local monastic committees.
• The spiritual aim remains the same: intensified discipline, teaching, and merit through restraint and study during the season.

If you’d like, I can share more detailed notes on how each tradition approaches Chaturmas (including typical daily routines and verses recited during this period).
